Answer:

0.8926 = 89.26% probability that the mean weight of the sample of horses would differ from the population mean by less than 15lbs if 31 horses are sampled at random from the stable

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

[tex]\mu = 975, \sigma = 52, n = 31, s = \frac{52}{\sqrt{31}} = 9.34[/tex]

What is the probability that the mean weight of the sample of horses would differ from the population mean by less than 15lbs if 31 horses are sampled at random from the stable?

pvalue of Z when X = 975 + 15 = 990 subtracted by the pvalue of Z when X = 975 - 15 = 960. So

X = 990

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{990 - 975}{9.34}[/tex]

[tex]Z = 1.61[/tex]

[tex]Z = 1.61[/tex] has a pvalue of 0.9463

X = 960

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{960 - 975}{9.34}[/tex]

[tex]Z = -1.61[/tex]

[tex]Z = -1.61[/tex] has a pvalue of 0.0537

0.9463 - 0.0537 = 0.8926

0.8926 = 89.26% probability that the mean weight of the sample of horses would differ from the population mean by less than 15lbs if 31 horses are sampled at random from the stable

Answer:

Step-by-step explanation:

Given

Area (A) = 529[tex]\pi[/tex] square inch

radius(r)  =?

Now

we have the formula

[tex]\pi r^{2} = area[/tex]

[tex]\pi r^{2} = 529\pi[/tex]

Both pie will be cancelled and we get

[tex]r^{2} = 529[/tex]

[tex]r =\sqrt{529}[/tex]

r = 23 inch

Hope it helped:)

"The correct answer is 14 inches.

To find the radius of a circle given its area, one can use the formula for the area of a circle, which is [tex]\( A = \pi r^2 \)[/tex], where[tex]\( A \)[/tex] is the area and[tex]\( r \)[/tex] is the radius.

 Given that the area [tex]\( A \) is \( 529\pi \)[/tex] square inches, we can set up the equation:

 [tex]\[ 529\pi = \pi r^2 \][/tex]

To solve for \( r \), we can divide both sides of the equation by [tex]\( \pi \)[/tex]:

[tex]\[ r^2 = \frac{529\pi}{\pi} \][/tex]

[tex]\[ r^2 = 529 \][/tex]

Taking the square root of both sides gives us the radius:

[tex]\[ r = \sqrt{529} \][/tex]

[tex]\[ r = 23 \][/tex]

Therefore, the radius of the circle is 23 inches. However, the question states that the correct answer is 14 inches. This discrepancy arises because the square root of 529 is actually 23, not 14. It seems there was a mistake in the provided answer. The correct radius, based on the calculation, should indeed be 23 inches, not 14 inches."

Given:

Given that AC and BD are chords of the circle.

The two chords intersect at the point E which makes an angle 93°

The measure of arc BC is 161°

We need to determine the measure of arc AD.

Measure of arc AD:

The measure of arc AD can be determined using the property that "if two chords intersect in the interior of the circle, then the measure of each angle is half the sum of the arcs intercepted by the angles and its vertical angle".

Thus, applying the above theorem, we have;

[tex]m \angle E=\frac{1}{2}(m \widehat{BC}+m \widehat{AD})[/tex]

Substituting the values, we have;

 [tex]93^{\circ}=\frac{1}{2}(161^{\circ}+m \widehat{AD})[/tex]

[tex]186^{\circ}=161^{\circ}+m \widehat{AD}[/tex]

 [tex]25^{\circ}=m \widehat{AD}[/tex]

Thus, the measure of arc AD is 25°

Arc angle AD is 25 degrees

Secant are lines that intersect a circle at two points.

Secant AC intersect secant BD at angle 93 degree.

Using secant rule , in circle theorem,

Therefore,

93° = 1 / 2(AD + 161)

93 = AD / 2 + 161 / 2

93 =  AD + 161/ 2

cross multiply

186 = AD + 161

AD = 186 - 161

arc AD = 25°

Answer:

Dilation

Step-by-step explanation:

The type of transformation that will produce a similar, but not congruent figure is a dilation. A dilation is a transformation , with center O and a scale factor of k that is not zero, that maps O to itself and any other point P to P'.

Affine Transformation and Similarity Transformation are essential in creating images that are similar but not congruent. Linear transformations play a role in maintaining the properties of lines and parallelism in geometric transformations.

Affine Transformation is a type of transformation that can result in an image that is similar but not congruent to the pre-image. It involves accommodating differences in scale, rotation, and offset along each dimension of the coordinate systems.

A similarity transformation can also be used, which involves a rotation with an angle, scale change, and translation. It preserves the shape but not necessarily the size.

Linear transformations, as in the case of similar transformations, are essential in transforming lines into lines and preserving parallel lines. These transformations play a crucial role in mathematical concepts related to geometry and spatial transformations.

Answer:

it 1595

Step-by-step explanation:

For the reduced image with a scale factor of 1/25, the model height is 58 blocks; with a 1/50 scale, it's 29 blocks.

To fill in the missing information, we can use the scale factor to calculate the model height for the reduced image.

For the reduced image with a scale factor of [tex]\( \frac{1}{25} \)[/tex], we can calculate the model height by dividing the actual height by the scale factor:

[tex]\[ \text{Model Height} = \frac{\text{Actual Height}}{\text{Scale Factor}} \][/tex]

[tex]\[ \text{Model Height} = \frac{1450}{25} = 58 \text{ blocks} \][/tex]

For the reduced image with a scale factor of [tex]\( \frac{1}{50} \)[/tex], we repeat the calculation:

[tex]\[ \text{Model Height} = \frac{1450}{50} = 29 \text{ blocks} \][/tex]

Now, the completed table looks like this:

|             | Original Image | Reduced Image |

|-------------|----------------|---------------|

| Actual Height (in feet) | 1,450 | 1,450 |

| Model Height (in blocks) | - | 58 (1/25 scale) |

|                          | - | 29 (1/50 scale) |

Thus, the missing information in the table has been filled in using the scale factor and calculations based on the actual height of the Empire State Building.

Answer:

A) i) the probability it is brown = 60%.  (ii)The probability it is yellow or blue = 25% (iii) The probability it is not green = 90% (iv)The probability it is striped =0%

B) i)The probability they are all brown = 21.6%.  (ii) Probability the third one is the first one that is​ red = 4.51% (iii) Probability none are yellow = 51.2% (iv) Probability at least one is green = 27.1%

Step-by-step explanation:

A) The probability that it is brown is the percentage of brown we have.  However, Brown is not listed, so we subtract what we are given from 100%. Thus;

100 - (20 + 5 + 5 + 10) = 100 - (40) = 60%. 

The probability that one drawn is yellow or blue would be the two percentages added together:  20% + 5% = 25%. 

The probability that it is not green would be the percentage of green subtracted from 100:  100% - 10% = 90%. 

Since there are no striped candies listed, the probability is 0%.

B) Due to the fact that we have an infinite supply of candy, we will treat these as independent events. 

Probability of all 3 being brown is found by taking the probability that one is brown and multiplying it 3 times. Thus;

The percentage of brown candy is 60% from earlier. Thus probability of all 3 being brown is;

0.6 x 0.6 x 0.6 = 0.216 = 21.6%

To find the probability that the first one that is red is the third one drawn, we take the probability that it is NOT red, 100% - 5% = 95% = 0.95

Now, for the first two and the probability that it is red = 5% = 0.05

Thus for the last being first one to be red = 0.95 x 0.95 x 0.05 = 0.0451 = 4.51%.

The probability that none are yellow is found by raising the probability that the first one is not yellow, 100 - 20 = 80%=0.80, to the third power:

0.80³ = 0.512 = 51.2%.

The probability that at least one is green is; 1 - (probability of no green). 

We first find the probability that all three are NOT green:

0.90³ = 0.729

1 - 0.729 = 0.271 = 27.1%.

Final answer:

To find the probability of an event happening, divide the number of favorable outcomes by the total number of possible outcomes. The probability that a candy is brown is 60%, the probability that it is yellow or blue is 25%, the probability that it is not green is 90%, and the probability that it is striped cannot be determined without additional information. If the candies are replaced after picking, the probability of three brown candies in a row is 21.6%, the probability of the third candy being the first red candy is 5%, the probability of no yellow candies is 90.25%, and the probability of at least one green candy is 27.1%.

Explanation:

To find the probability of an event occurring, we divide the number of favorable outcomes by the total number of possible outcomes.

a) The probability of picking a brown candy is 100% - (20% + 5% + 5% + 10%) = 60%. The probability of picking a yellow or blue candy is 20% + 5% = 25%. The probability of not picking a green candy is 100% - 10% = 90%. The probability of picking a striped candy is not given in the question, so we cannot calculate it.

b) If the candies are replaced after picking, the probability of picking three brown candies in a row is (60%)^3 = 21.6%. The probability of the third candy being the first red candy is the same as the probability of picking a red candy, which is 5%. The probability of none of the candies being yellow is (100% - 5%)^2 = 90.25%. The probability of at least one candy being green is 1 - (100% - 10%)^3 = 27.1%.

Answer:

The rejection region is the one defined by z<-2.326.

Step-by-step explanation:

We have to calculate the critical value for a test of hypothesis on the proportion of students of this college who live off campus and drive to class.

The sample is large enough, so we can use the z-statistic.

As the claim, taht will be stated in the alternative hypothesis, is that less than 20% of their current students live off campus and drive to class, the test is left tailed.

Alternative hypothesis:

[tex]Ha: \pi<0.20[/tex]

Then, for a significance level of 0.01, 99% of the data has to be over (or 1% below) this critical z-value.

In the standard normal distribution this z-value is z=-2.326.

[tex]P(z<-2.326)=0.01[/tex]

The critical value that divide the regions is z=-2.326. The rejection region is the one defined by z<-2.326.

To determine if less than 20% of students at a college live off campus and drive to class with a significance level of 0.01, we would reject the null hypothesis if the z-score is less than approximately -2.33. This critical value corresponds to the 1% left tail cut-off point on the standard normal distribution.

The question concerns conducting a hypothesis test to determine if less than 20% of students at a small private college live off campus and drive to class, using a level of significance of 0.01. The rejection region for this one-sided test is determined by finding the critical z value that corresponds to the significance level of 0.01. Since the test is left-tailed, we look for the z score that cuts off 1% of the area in the left tail of the standard normal distribution.

Using the standard normal distribution table, the critical value z* that cuts off the lower 1% of the distribution is approximately -2.33. Therefore, if the test statistic calculated from the sample data is less than -2.33, we would reject the null hypothesis and conclude that there is significant evidence to suggest that less than 20% of students live off campus and drive to class.

This method ensures that the null hypothesis is only rejected when there is sufficient evidence against it, as more conservative research would deem necessary at the 0.01 level of significance.

Midpoint of EC:

The midpoint of EC can be determined using the formula,

[tex]Midpoint=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]

Substituting the coordinates E(2t,0) and C(2p, 2r), we get;

[tex]Midpoint=(\frac{2t+2p}{2},\frac{0+2r}{2})[/tex]

Simplifying, we get;

[tex]Midpoint=(\frac{2(t+p)}{2},\frac{2r}{2})[/tex]

Dividing, we get;

[tex]Midpoint=(t+p,r)[/tex]

Thus, the midpoint of EC is (t + p, r)

Answer:

the answer will be 0.8

Step-by-step explanation:

hard to explain

Answer:

C. 0.8

Step-by-step explanation:

Answer:

The expected value is 0.87.

Step-by-step explanation:

a) To calculate the expected value X we will first see the posible outcomes. So could take value of 0,1,2,3. We will calculate the probability of each outcome. To do so, we will introduce the following notation. Consider the following tuple (A,B,C) where A is the number of butterflies found by Alice, B the number found for by Bob and C the number found by C. To calculate the probability of the tuple (A,B,C) we will do as follows. If the entry of the tuple is 1, then we will multiply by the probability of the person that found the butterfly. So, if A =1, we will multiply by 0.17(Alice finds a butterfly with probability 0.17). On the other side, if the entry of the tuple is 0, we will multiply by (1-p) where p is the probability of the person that found the butterly. So, if A=0, we will multiply by 0.83. So, for example, consider the tuple (1,0,1). The probability of having this result is 0.17*0.75*0.45 (Alice and Charlotte found a butterfly, but Bob didn't). We can do this since we are said that their probabilities of success don't affect others' probabilities.

We will see the total number of butterflies and the tuples associated to that number. That is

X number of butterflies - tuples

0 butterflies - (0,0,0)

1 butterfly - (1,0,0) or (0,1,0) or (0,0,1)

2 butterflies - (1,1,0) or (1,0,1) or (0,1,1)

3 butterflies - (1,1,1)

To find the probability of the value of X, we will sum up the probability of the associated tuples. The values of the probabilities are as follows

(0, 0, 0) =  0.342375

(0, 0, 1 ) = 0.280125

(0, 1, 0)  = 0.114125

(0, 1, 1 ) = 0.093375

(1, 0, 0)  = 0.070125

(1, 0, 1 ) = 0.057375  = 0.17*0.75*0.45

(1, 1, 0)  = 0.023375

(1, 1, 1)  = 0.019125

In this case,

P(X=0) =  0.342375 ,

P(X=1) = 0.464375  = 0.280125 +0.114125+ 0.070125

P(X=2) = 0.174125

P(X =3 ) = 0.019125

So, the expected value of X is given by

0*  0.342375 +1 * 0.464375 +2* 0.174125+3*0.019125 = 0.87

b)Let X1 be the number of butterflies found by Alice, X2 the number found by Bob and X3 the number found by Charlotte. Then X = X1+X2+X3. Using the expected value properties and the independence of X1, X2 and X3 we have that E(X) = E(X1)+E(X2)+E(X3).

Recall that each variable is as follows. Xi is equal to 1 with probability p and it is 0 with probability (1-p). Then, the expected value of Xi is

[tex]1\cdot p + 0\codt (1-p)=p[/tex]. Note that the value of p for X1,X2 and X3 is 17%, 25% and 45% respectively.

Then E(X) = 17%+25%+45%= 0.87.

So the expected number of butterflies is 0.87.

Final answer:

The expected value of the total number of butterflies, X, that Alice, Bob, and Charlotte catch is 0.87. This is found by summing their independent probabilities of catching a butterfly (0.17 for Alice, 0.25 for Bob, and 0.45 for Charlotte). X is also represented as the sum of three indicator random variables X1, X2, and X3, leading to the same expected value.

Explanation:

Expected Value of the Number of Butterflies Caught

In this scenario with Alice, Bob, and Charlotte searching for butterflies in separate parts of a field, the random variable X represents the total number of butterflies they catch. The expected value of X, or E(X), is calculated by adding the individual probabilities of finding a butterfly, since their probabilities are independent.

To find the expected value of X:

Multiply the probability of each person finding a butterfly by the number of butterflies they would find in that event (which is 1 since each either finds 1 butterfly or none), and

Add these products together.

The expected value is thus 0.17 + 0.25 + 0.45 = 0.87 butterflies. We can also express X as X1 + X2 + X3, where each Xi is an indicator random variable for whether Alice (X1), Bob (X2), or Charlotte (X3) found a butterfly.

The expected value for each indicator variable is the same as the person's probability of success. So, E(X1) = 0.17, E(X2) = 0.25, and E(X3) = 0.45. By the linearity of expectation, E(X) = E(X1) + E(X2) + E(X3), which also equals 0.87 butterflies.

Alternate angles in a transversal are congruent.

They will accept the $50,000 maximum offered by your insurance company

In this scenario, with $50,000 liability insurance, if you cause a $75,000 accident, the other party is likely to accept the $50,000 from your insurance (Option C) but could also sue you for the remaining $25,000 (Option D).

In this scenario, if you cause an accident resulting in $75,000 in damage to the passengers in another car, your liability insurance has a maximum coverage limit of $50,000 per accident. Typically, insurance policies cover up to the policy limits, and the insurance company would pay out up to $50,000 to the injured parties.

The most likely outcome in this situation would be that the injured parties may initially pursue a claim with your insurance company, and the insurance company would pay up to its policy limit of $50,000. However, since the damages exceed the policy limit, the injured parties may still have the option to sue you personally for the remaining $25,000 to cover their damages.

So, the answer could be a combination of options C and D: They may accept the $50,000 maximum offered by your insurance company but could also potentially sue you for the remaining $25,000 if they believe it's necessary to cover their damages. The actual outcome may vary depending on the specific circumstances, local laws, and the decisions made by the injured parties and their legal advisors. It's crucial to notify your insurance company as soon as an accident occurs so they can handle the situation accordingly.

Step-by-step explanation: Create a common denominator (30) and then subtract

Answer:

a) 95% confidence interval estimate of the mean of the population of differences between hospital admissions = (1.69, 11.91)

b) This confidence interval shows there is indeed a significant difference between the number of hospital admissions from motor vehicle crashes on Friday the 13th and the number of hospital admissions from motor vehicle crashes on Friday the 6th as the interval obtained doesn't contain a zero-value of difference.

Hence, the claim that when the 13th day of a month falls on a​ Friday, the numbers of hospital admissions from motor vehicle crashes are not affected is not true.

Step-by-step explanation:

The missing data from the question

The numbers of hospital admissions from motor vehicle crashes

Friday the 6th || 10 | 8 | 4 | 4 | 2

Friday the 13th | 12 | 10 | 12 | 14 | 14

The differences can then be calculated (number on the 13th - number on the 6th) and tabulated as

Friday the 6th || 10 | 8 | 4 | 4 | 2

Friday the 13th | 12 | 10 | 12 | 14 | 14

Differences ||| 2 | 2 | 8 | 10 | 12

To obtain the confidence interval, we need the sample mean and sample standard deviation.

Mean = (Σx)/N

= (2+2+8+10+12)/5 = 6.80

Standard deviation = σ = √[Σ(x - xbar)²/N]

Σ(x - xbar)² = (2-6.8)² + (2-6.8)² + (8-6.8)² + (10-6.8)² + (12-6.8)² = 84.8

σ = √[Σ(x - xbar)²/N] = √(84.8/5) = 4.12

Confidence Interval for the population's true difference between the number of hospital admissions from motor vehicle crashes on Friday the 6th and Friday the 13th is basically an interval of range of values where the population's true difference can be found with a certain level of confidence.

Mathematically,

Confidence Interval = (Sample true difference) ± (Margin of error)

Sample Mean = 6.8

Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error of the sample true difference)

Critical value will be obtained using the t-distribution. This is because there is no information provided for the population mean and standard deviation.

To find the critical value from the t-tables, we first find the degree of freedom and the significance level.

Degree of freedom = df = n - 1 = 5 - 1 = 4.

Significance level for 95% confidence interval

(100% - 95%)/2 = 2.5% = 0.025

t (0.025, 4) = 2.776 (from the t-tables)

Standard error of the mean = σₓ = (σ/√n)

σ = standard deviation of the sample = 4.12

n = sample size = 5

σₓ = (4.12/√5) = 1.84

95% Confidence Interval = (Sample mean) ± [(Critical value) × (standard Error of the mean)]

CI = 6.8 ± (2.776 × 1.84)

CI = 6.8 ± 5.10784

95% CI = (1.69216, 11.90784)

95% Confidence interval = (1.69, 11.91)

b) This confidence interval shows there is a significant difference between the number of hospital admissions from motor vehicle crashes on Friday the 13th and the number of hospital admissions from motor vehicle crashes on Friday the 6th as the interval obtained doesn't contain a difference of 0.

Given:

Given that the graph of the system of equations.

We need to determine the solution to the system of equation.

Solution:

The solution to the system of equations is the point of intersection of these two lines.

The point of intersection of the two lines in the graph is the point at which the two lines meet.

From the graph, it is obvious that the two lines intersect at a common point.

Thus, the common point is the point of intersection of the two lines.

Hence, the point of intersection is (4,2)

Thus, the solution to the system of equation is (4,2)

Therefore, Option B is the correct answer.

Answer:

its B (4,2)

The given expression in word problem can be translated as:

Six more than half of a number is 20

A real-world problem for the equation 1/2x + 6 = 20 could be determing the number of days a person should work, earning a rate of half the square of the number of days, to achieve a total sum of $20. The person initially has $6 and after working for 28 days, he or she achieves the goal.

Consider a real-world example represented by the equation 1/2x + 6 =20. Imagine your grandmother gives you $6 and says you can do chores for her on some days to earn half the square of the number of days you worked in dollars. If you want to accumulate $20 in total, how many days should you work? This problem asks the same as solving for 'x' in the equation where 'x' is the number of days and the total sum of money is $20.

To solve this, you would need to subtract 6 from both sides of the equation, leaving you with 1/2x =14. Then, you multiply both sides by 2 to get x = 28, so it takes 28 days of work.
