The factors that cause Earth to experience seasons are:

1. the tilt of Earth’s axis

2. the directness of the Sun’s rays

Factors that result in the earth experiencing the seasons should be:

The reason why the Earth contains various seasons because it deals with the variation of the sun's rays angles and the earth titles to the 23.5 degrees on its axis. Also along with the earth rotation, the earth orbits should be around to the sun because of which various parts should be exposed to the different amount of lights

The mean of the 90 heights is 63.4 in and the mean of the 90 pulse rates is 77.9 beats per minute. Find the best predicted pulse rate of a woman who is 66 in tall. Use a significance level of alpha equals 0.01.

Answers

The best-predicted pulse rate for a woman who is 66 inches tall, using the given regression equation 18.4 + 0.930x, is approximately 79.78 beats per minute.

To predict the pulse rate of a woman who is 66 inches tall using the given regression equation, we plug in the height (x = 66) into the equation:

ModifyingAbove y with caret = 18.4 + 0.930x

Substituting x = 66:

ModifyingAbove y with caret = 18.4 + 0.930(66)

Perform the calculation:

ModifyingAbove y with caret = 18.4 + 61.38

ModifyingAbove y with caret = 79.78

Therefore, the best-predicted pulse rate for a woman who is 66 inches tall is approximately 79.78 beats per minute. This prediction assumes that the relationship between height and pulse rate holds for this particular height value.

At the Canada Open Tennis Championship, a statistician keeps track of every serve that a player hits during the tournament. The statistician reported that the mean serve speed of a particular player was 99 miles per hour (mph) and the standard deviation of the serve speeds was 15 mph.
If nothing is known about the shape of the distribution, give an interval that will contain the speeds of at least eight-ninths of the player's serves.

a) 54 mph to 144 mph
b) 39 mph to 159 mph
c) 144 mph to 189 mph
d) 69 mph to 129 mph

Answers

Answer:

a) 54 mph to 144 mph

Step-by-step explanation:

We don't know the shape of the distribution, so we use Chebyshev's Theorem to solve this question. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

At least eight-ninths of the player's serves.

8/9 is approximately 89%

So

Mean: 99, standard deviation: 15

99 - 3*15 = 54

99 + 3*15 = 144

So the correct answer is:

a) 54 mph to 144 mph

The fifth degree Taylor polynomial of g(x) is increasing around x=-1

Step-by-step explanation:

Yes, you can do the derivative of the fifth degree Taylor polynomial, but notice that its derivative evaluated at x =-1 will give zero for all its terms except for the one of first order, so the calculation becomes simple:

[tex]P_5(x)=g(-1)+g'(-1)\,(x+1)+g"(-1)\, \frac{(x+1)^2}{2!} +g^{(3)}(-1)\, \frac{(x+1)^3}{3!} + g^{(4)}(-1)\, \frac{(x+1)^4}{4!} +g^{(5)}(-1)\, \frac{(x+1)^5}{5!}[/tex]

and when you do its derivative:

1) the constant term renders zero,

2) the following term (term of order 1, the linear term) renders: [tex]g'(-1)\,(1)[/tex] since the derivative of (x+1) is one,

3) all other terms will keep at least one factor (x+1) in their derivative, and this evaluated at x = -1 will render zero

Therefore, the only term that would give you something different from zero once evaluated at x = -1 is the derivative of that linear term. and that only non-zero term is: [tex]g'(-1)= 7[/tex] as per the information given. Therefore, the function has derivative larger than zero, then it is increasing in the vicinity of x = -1

Answers

Answer:

Total no  of different ways can the 4 computers be chosen  = 70

Step-by-step explanation:

Given -

A computer retail store has 8 personal computers in stock.A buyer wants to purchase 4 of them.

(Using the combination formula)

The combination of n events taking r at a time = [tex]\mathbf{\binom{n}{r}}[/tex]

where n = 8 and r = 4

Total no  of different ways can the 4 computers be chosen = [tex]\mathbf{\binom{8}{4}}[/tex]

    =  [tex]\boldsymbol{\frac{8!}{(4!)(4!)}}[/tex]

=   70

Final answer:

The number of different ways that 4 computers can be chosen from a stock of 8 is 70.

Explanation:

The number of different ways that 4 computers can be chosen from a stock of 8 is determined by the concept of combinations. In this case, we want to find the number of combinations of 8 items taken 4 at a time. The formula for combinations is given by:



C(n, r) = n! / r!(n-r)!



where n is the total number of items and r is the number of items to be chosen. Applying the formula to this problem, we have:



C(8, 4) = 8! / 4!(8-4)!



Simplifying the expression, we get:



C(8, 4) = 8! / 4!4!



Using the factorial function, we can compute:



C(8, 4) = 8 × 7 × 6 × 5 / (4 × 3 × 2 × 1)



C(8, 4) = 70



Therefore, there are 70 different ways that the 4 computers can be chosen from the stock of 8.

Last month, Ginger's hotel ran an occupancy rate of 85%. Her competitive set had 150,000 room nights included within it that were available for sale during that month. During that month, the competitive set sold a total of 115,000 rooms. What was the approximate occupancy rate INDEX last month for Ginger's hotel? It's one of the following answer; 78%, 92%, 87% or 39%? Provide details.

Answers

Given Information:

Occupancy rate of Ginger’s hotel = 85%

Competitive set available rooms = 150,000

Competitive set sold rooms = 115,000

Required Information:

Occupancy rate INDEX = ?

Answer:

Occupancy rate INDEX = 111%

Step-by-step explanation:

The occupancy rate INDEX is given by

Occupancy rate INDEX = Occupancy rate of Ginger’s hotel/Occupancy  rate of competitive set

We are given the occupancy rate of Ginger’s hotel so we need to first find out occupancy  rate of competitive set which is given by

Occupancy rate of competitive set = Competitive set sold rooms/Competitive set available rooms

Occupancy rate of competitive set = 115,000/150,000

Occupancy rate of competitive set = 0.7667

Occupancy rate of competitive set ≈ 76.67%

Finally, we can now find the occupancy rate INDEX

Occupancy rate INDEX = Occupancy rate of Ginger’s hotel/Occupancy rate of competitive set

Occupancy rate INDEX = 85/76.67

Occupancy rate INDEX = 1.108

Occupancy rate INDEX = 110.8%

Occupancy rate INDEX ≈ 111%

Therefore, the approximate occupancy rate INDEX last month for Ginger's hotel is 111%

Answers

Find the given attachments for complete answer

Answer:

The 95% confidence interval for the proportion for the American adults who believed in astrology is (0.23, 0.27).

This means that we can claim with 95% confidence that the true proportion of all American adults who believed in astrology is within 0.23 and 0.27.

Step-by-step explanation:

We have to construct a 95% confidence interval for the proportion.

The sample proportion is p=0.25.

[tex]p=X/n=501/2004=0.25[/tex]

The standard deviation can be calculated as:

[tex]\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.25*0.75}{2004}}=\sqrt{ 0.000094 }=0.01[/tex]

For a 95% confidence interval, the critical value of z is z=1.96.

The margin of error can be calculated as:

[tex]E=z\cdot \sigma_p=1.96*0.01=0.0196[/tex]

Then, the lower and upper bounds of the confidence interval can be calculated as:

[tex]LL=p-E=0.25-0.0196=0.2304\approx0.23\\\\UL=p+E=0.25+0.0196=0.2696\approx 0.27[/tex]

The 95% confidence interval for the proportion for the American adults who believed in astrology is (0.23, 0.27).

This means that we can claim with 95% confidence that the true proportion of all American adults who believed in astrology is within 0.23 and 0.27.

A bottler of drinking water fills plastic bottles with a mean volume of 1,000 milliliters (mL) and standard deviation The fill volumes are normally distributed. What proportion of bottles have volumes greater than

Answers

Answer:

84.13% of bottles will have volume greater than 994 mL

Step-by-step explanation:

Mean volume = u = 1000

Standard deviation = [tex]\sigma[/tex] = 6

We need to find the proportion of bottles with volume greater than 994. So our test value is 994. i.e.

x = 994

Since the data is normally distributed we will use the concept of z-score to find the required proportion. First we convert 994 to its equivalent z-score, then using the z-table we will find the corresponding value of proportion. The formula to calculate the z score is:

[tex]z=\frac{x-u}{\sigma}[/tex]

Substituting the values, we get:

[tex]z=\frac{994-1000}{6}=-1[/tex]

This means 994 is equivalent to a z score of -1. Now we will find the proportion of z values which are greater than -1 from the z table.

i.e. P(z > -1)

From the z-table this value comes out to be:

P(z >- 1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413

Since, 994 is equivalent to a z score of -1, we can write that proportion of values which will be greater than 994 would be:

P( X > 994 ) = P( z > -1 ) = 0.8413 = 84.13%

Final answer:

To find the proportion of bottles with more than 994 mL, calculate the z-score and use a z-table. Approximately 93.32% of bottles are filled with more than 994 mL.

Explanation:

To determine the proportion of bottles with volumes greater than 994 mL, we need to use the properties of the standard normal distribution. The mean volume of a bottle is given as 1000 mL with a standard deviation of 4 mL. We first calculate the z-score for 994 mL, which is the number of standard deviations 994 mL is from the mean.

Z = (X - μ) / σ = (994 mL - 1000 mL) / 4 mL = -1.5

Using a z-table or standard normal distribution calculator, we can find the proportion of the area to the right of z = -1.5, which represents the proportion of bottles filled with more than 994 mL. The area to the right of z = -1.5 is approximately 0.9332. Therefore, about 93.32% of the bottles are expected to have volumes greater than 994 mL.

The thumb length of fully grown females of a certain type of frog is normally distributed with a mean of 8.59 mm and a standard deviation of 0.63 mm. Calculate the probability that a randomly selected frog of this type has thumb length longer than 9.08 mm.

Answers

Answer:

21.77% probability that a randomly selected frog of this type has thumb length longer than 9.08 mm.

Step-by-step explanation:

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.

In this problem, we have that:

[tex]\mu = 8.59, \sigma = 0.63[/tex]

Calculate the probability that a randomly selected frog of this type has thumb length longer than 9.08 mm.

This is 1 subtracted by the pvalue of Z when X = 9.08. So

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

[tex]Z = \frac{9.08 - 8.59}{0.63}[/tex]

[tex]Z = 0.78[/tex]

[tex]Z = 0.78[/tex] has a pvalue of 0.7823

1 - 0.7823 = 0.2177

21.77% probability that a randomly selected frog of this type has thumb length longer than 9.08 mm.

Is there enough evidence to show that the true proportion is lower than 60%? Assume that significance level of 0.05. Use the hypothesis testing template provided.'

Answers

Answer:

We accept H₀ we don´t have enough evidence to conclude that a consumer group position is correct

Step-by-step explanation:

We have a case of test of proportion, as a consumer group is suspicious of the claim and think the proportion is lower we must develop a one tail test (left tail) Then

1.- Test hypothesis:

Null hypothesis  H₀                   P = P₀

Alternative hypothesis  Hₐ       P < P₀

2.- At significance level of α  = 0,05   Critical value

z(c)  =  -1,64

3.-We compute z(s) value as:

z(s)  =  ( P - P₀ )/ √P*Q/n      where   P = 44/80     P = 0,55   and Q = 0,45

P₀ = 0,6   and  n = 80

Plugging all these values in the equation we get:

z(s)  = ( 0,55 - 0,6 ) / √(0,2475/80)

z(s)  =  - 0,05/ √0,0031

z(s)  =  - 0,05/0,056

z(s)  =  - 0,8928

4.-We compare  z(s)  and  z(c)

z(s) > z(c)      -0,8928 on the left side it means that z(s) is in the acceptance region so we accept H₀

In the data set below, what are the lower quartile, the median, and the upper quartile?

Lower Quartile: 2

Upper Quartile: 5.25

Median: 3

Final answer:

In the given data set 2, 2, 2, 4, 5, 6, the lower quartile is 2, the median is 3, and the upper quartile is 5.

Explanation:

To find the lower quartile, median, and upper quartile of the given data set 2, 2, 2, 4, 5, 6, we first need to organize it in ascending order, which is already done. Next, we compute the median, which is the middle value when the data set is listed in order. Since there are six numbers, the median will be the average of the third and fourth numbers, (2+4)/2, which is 3.

To find the first quartile (Q1) or lower quartile, we take the median of the lower half of the data set, not including the median. This would be the median of the first three numbers: 2, 2, and 2, which is simply 2. To find the third quartile (Q3) or upper quartile, we look at the upper half of the data set, again not including the median. The median of the last three numbers 4, 5, and 6 is 5.

Therefore, the lower quartile is 2, the median is 3, and the upper quartile is 5.

Answers

Answer:

[tex]A(t) = 48833e^{0.0389t}[/tex]

The exponential growth rate is r = 0.0389

Step-by-step explanation:

An exponential function for the number of women graduating from​ 4-yr colleges in t years after 1930 can be given by the following equation:

[tex]A(t) = A(0)e^{rt}[/tex]

In which A(0) is the initial amount, and r is the exponential growth rate, as a decimal.

1930​, when 48,833 women earned a​ bachelor's degree

This means that [tex]A(0) = 48833[/tex]

2004​, when approximately 870,000

2004 is 74 years after 1930, which means that [tex]A(74) = 870000[/tex]

Applying to the equation:

[tex]A(t) = A(0)e^{rt}[/tex]

[tex]870000 = 48833e^{74r}[/tex]

[tex]e^{74r} = \frac{870000}{48833}[/tex]

[tex]\ln{e^{74r}} = \ln{\frac{870000}{48833}}[/tex]

[tex]74r = \ln{\frac{870000}{48833}}[/tex]

[tex]r = \frac{\ln{\frac{870000}{48833}}}{74}[/tex]

[tex]r = 0.0389[/tex]

So

[tex]A(t) = A(0)e^{rt}[/tex]

[tex]A(t) = 48833e^{0.0389t}[/tex]

Final answer:

To find an exponential function that fits the given data, determine the values of the base and the exponent. The exponential function that fits the data is y = 2.311 * 1.049^x. The exponential growth rate is approximately 1.049.

Explanation:

To find an exponential function that fits the data, we need to determine the values of the base and the exponent. Let's let the year be the input, x, and the number of women graduating be the output, y. The general form of an exponential function is y = ab^x, where a is the initial value and b is the growth rate. Substituting the given data, we have the equation:

48,833 = a * b1930

870,000 = a * b2004

By dividing the second equation by the first equation, we can eliminate a:

870,000 / 48,833 = (a * b2004) / (a * b1930)

17.821 = b2004-1930

17.821 = b74

Taking the log base b of both sides, we get:

logb 17.821 = 74

Solving for b using logarithmic properties, we find:

b = 17.8211/74

b ≈ 1.049

Now that we have the value of b, we can substitute it into one of the original equations to find a:

48,833 = a * 1.0491930

Solving for a, we get:

a ≈ 2.311

Therefore, the exponential function that fits the data is y = 2.311 * 1.049x. The exponential growth rate is approximately 1.049.

A glider begins its flight 3/4 mile above the ground. After 45 minutes, it is 3/10 mile above the ground. Find the change in height of the glider. If it continues to descend at this rate, how long does the entire descent last?

Answers

Answer:

1 hour 15 Minutes

Step-by-step explanation:

The glider begins its flight [tex]\dfrac{3}{4}[/tex] mile above the ground.

Distance above the ground after 45 minutes =[tex]\frac{3}{10} \:mile[/tex]

Change in height of the glider

[tex]=\frac{3}{4}-\frac{3}{10} \\\\=\frac{15-6}{20}\\\\=\frac{9}{20} miles[/tex]

Next, we determine how long the entire descent last.

Expressing the distance moved as a ratio of time taken

[tex]\frac{9}{20} \:miles : 45 \:minutes\\\\\frac{3}{10}\:miles:x \:minutes\\\\x=45X\frac{3}{10}\div\frac{9}{20} =30 Minutes[/tex]

Therefore: Total Time taken =45+30=75 Minutes

=1 hour 15 Minutes

You deposit $2500 in an account that pays 6 percent annual interest. Find the balance after 3
years if the interest is compounded with the given frequency.

Answers

Answer:

$2,977.54

Step-by-step explanation:

You are going to use the compound interest formula:

[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]

P = initial balance

r = interest rate

n = number of times compounded annually

t = time

First, change 6% into the decimal form:

6% -> [tex]\frac{6}{100}[/tex] -> 0.06

Next, lets plug in the values:

[tex]A=2,500(1+\frac{0.06}{1} )^{3(1)}[/tex]

[tex]A=2,977.54[/tex]

Your answer will be $2,977.54
