Answer:

I believe the correct statements are 1), 2), and 3).

The statements provided in the question are all true. The sphere has a radius of 4 cm (A), the diameter's length is twice the length of the radius (B), and the volume of the sphere is 256/3 π cm³ (C).

A) The sphere has a diameter of 8 cm, which is the distance between two points on the surface of the sphere passing through its center. By definition, the diameter is twice the length of the radius. Thus, to find the radius of the sphere, we divide the diameter by 2:

Radius = Diameter / 2

Radius = 8 cm / 2

Radius = 4 cm

B) This statement is true. As mentioned earlier, the diameter of the sphere (8 cm) is indeed twice the length of its radius (4 cm).

C) The volume of a sphere can be calculated using the formula:

Volume = (4/3) * π * Radius³

Now, let's calculate the volume using the given radius:

Volume = (4/3) * π * (4 cm)³

Volume = (4/3) * π * 64 cm³

Volume = 256/3 * π cm³

Hence the correct option is (a), (b) and (c).

Answer:

[tex]S_{1 } (x,y) = (0.333, 0.815)[/tex] (Absolute minimum) and [tex]S_{2} (x,y) = (-1, 2)[/tex] (Absolute maximum)

Step-by-step explanation:

The critical points are determined with the help of the First Derivative Test:

[tex]f'(x) = 3\cdot x ^{2} +2\cdot x -1[/tex]

[tex]3\cdot x^{2} + 2\cdot x - 1 = 0[/tex]

The critical points are:

[tex]x_{1} \approx 0.333[/tex] and [tex]x_{2} \approx -1[/tex]

The Second Derivative Test offers a criterion to decide whether critical point is an absolute maximum and whether is an absolute minimum:

[tex]f''(x) = 6\cdot x +2[/tex]

[tex]f''(x_{1}) = 3.998[/tex] (Absolute minimum)

[tex]f''(x_{2}) = -4[/tex] (Absolute maximum)

The critical points are:

[tex]S_{1 } (x,y) = (0.333, 0.815)[/tex] (Absolute minimum) and [tex]S_{2} (x,y) = (-1, 2)[/tex] (Absolute maximum)

The global maximum is at x = -1 with f(-1) = 2, and the global minimum is at x = -2 with f(-2) = -1.

To find the global and local maxima and minima of the function f(x) = [tex]x^3 + x^2[/tex] − x + 1 over the interval [-2, 1/2], follow these steps:

Find critical points: First, we need to find the derivative of the function f(x):

f'(x) = [tex]3x^2[/tex]+ 2x - 1

Solve f'(x) = 0 to find critical points within the interval:

[tex]3x^2[/tex]+ 2x - 1 = 0

Using the quadratic formula x = (-b ± √(b²-4ac)) / 2a, where a = 3, b = 2, and c = -1:

x = [-2 ± √(4 + 12)] / 6

x = [-2 ± 4] / 6

This gives two solutions:

x = 1/3 and x = -1

Both are within the interval [-2, 1/2], so we consider these as critical points.

Second Derivative Test (SDT): Find the second derivative to apply the SDT:

f''(x) = 6x + 2

Evaluate f''(x) at the critical points:

f''(-1) = 6(-1) + 2 = -4 (which is negative, indicating a local maximum)

f''(1/3) = 6(1/3) + 2 = 4 (which is positive, indicating a local minimum)

Evaluate the function at the endpoints: Compute f(x) at the bounds of the interval:

f(-2) = (-2)³ + (-2)² - (-2) + 1 = -8 + 4 + 2 + 1 = -1

f(1/2) = (1/2)³ + (1/2)² - (1/2) + 1 = 1/8 + 1/4 - 1/2 + 1 = 7/8

Additionally, compute the function at the critical points:

f(-1) = (-1)³ + (-1)² - (-1) + 1 = -1 + 1 + 1 + 1 = 2

f(1/3) = (1/3)³ + (1/3)² - (1/3) + 1 = 1/27 + 1/9 - 1/3 + 1 ≈ 0.963

Interpret the results:

The maximum and minimum values for f(x) over [-2, 1/2] are:

Local maximum at x = -1 with f(-1) = 2

Local minimum at x = 1/3 with f(1/3) ≈ 0.963

Global maximum at x = -1 with f(-1) = 2

Global minimum at x = -2 with f(-2) = -1

Answer:

Correct option: (b).

Step-by-step explanation:

The correlation coefficient is a statistical degree that computes the strength of the linear relationship between the relative movements of the two variables (i.e. dependent and independent). It ranges from -1 to +1.

Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa. A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.

In statistics, a perfect positive correlation is represented by +1 and -1 indicates a perfect negative correlation.

The closer the correlation value is to 1 the stronger the relationship between the two variables.

Let,

X = car weight

Y = car reliability

Z = annual maintenance cost

It is provided that:

Corr. (X, Y) = -0.30

Corr. (X, Z) = 0.20

The correlation coefficient of car weight and car reliability is negative. This implies that there is a negative relation between the two variables, i.e. as the weight of the car increases the reliability decreases and vice-versa.

And the correlation coefficient of car weight and annual maintenance cost is positive. That is, the two variables move in the same direction, i.e. as the weight of the car increases the annual maintenance cost also increases.

The correlation coefficient value of (X, Y) is closer to 1 than that of (X, Z).

This implies that the relationship between car weight and car reliability is much more stronger that the relationship between car weight and annual maintenance cost.

Thus, all the provided statement are correct.

Hence, the correct option is (b).

Final answer:

The correlations indicate that heavier cars tend to be less reliable and cost more to maintain. (option b)  I, II, and III.

Explanation:

The given correlations between car weight and car reliability (-0.30) and car weight and annual maintenance cost (0.20) can be used to determine the relationship between these variables.

I. Heavier cars tend to be less reliable.

Based on the given correlations, the following statements are true:

Therefore, the correct answer is (option b)  I, II, and III.

Answer:

95% confidence interval for the population variance of the number of tissues per box is [5043.11 , 23401.31].

Step-by-step explanation:

We are given that a consumer magazine counts the number of tissues per box in a random sample of 15 boxes of No- Rasp facial tissues. The sample standard deviation of the number of tissues per box is 97.

Firstly, the pivotal quantity for 95% confidence interval for the population variance is given by;

                         P.Q. = [tex]\frac{(n-1)s^{2} }{\sigma^{2} }[/tex]  ~ [tex]\chi^{2}__n_-_1[/tex]

where, [tex]s^{2}[/tex]  = sample variance = [tex]97^{2}[/tex] = 9409

              n = sample of boxes = 15

           [tex]\sigma^{2}[/tex]  = population variance

Here for constructing 95% confidence interval we have used chi-square test statistics.

So, 95% confidence interval for the population variance, [tex]\sigma^{2}[/tex] is ;

P(5.629 < [tex]\chi^{2}__1_4[/tex] < 26.12) = 0.95  {As the critical value of chi-square at 14

                                         degree of freedom are 5.629 & 26.12}  

P(5.629 < [tex]\frac{(n-1)s^{2} }{\sigma^{2} }[/tex] < 26.12) = 0.95

P( [tex]\frac{5.629 }{(n-1)s^{2} }[/tex] < [tex]\frac{1}{\sigma^{2} }[/tex] < [tex]\frac{26.12 }{(n-1)s^{2} }[/tex] ) = 0.95

P( [tex]\frac{(n-1)s^{2} }{26.12 }[/tex] < [tex]\sigma^{2}[/tex] < [tex]\frac{(n-1)s^{2} }{5.629 }[/tex] ) = 0.95

95% confidence interval for [tex]\sigma^{2}[/tex] = [ [tex]\frac{(n-1)s^{2} }{26.12 }[/tex] , [tex]\frac{(n-1)s^{2} }{5.629 }[/tex] ]

                                                  = [ [tex]\frac{14 \times 9409 }{26.12 }[/tex] , [tex]\frac{14 \times 9409 }{5.629 }[/tex] ]

                                                  = [5043.11 , 23401.31]

Therefore, 95% confidence interval for the population variance of the number of tissues per box is [5043.11 , 23401.31].

Answer:

Step-by-step explanation:

The correct answer is (B).

Let X = the number of people that are displeased in a random sample of 25 people selected from a population of which 4.5% will be displeased regardless of the situation. Then X is a binomial random variable with n = 25 and p = 0.045.

P(X ≥ 2) = 1 – P(X ≤ 1) = 1 – binomcdf(n: 25, p: 0.045, x-value: 1) = 0.311.

P(X ≥ 2) = 1 – [P(X = 0) + P(X = 1)] = 1 – 0C25(0.045)0(1 – 0.045)25 – 25C1(0.045)1(1 – 0.045)24 = 0.311.

The probability that at least two people will be displeased in a random sample of 25 people is approximately 0.202.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

This problem can be solved using the binomial distribution since we have a fixed number of trials (selecting 25 people) and each trial has two possible outcomes (displeased or not displeased).

Let p be the probability of an individual being displeased, which is given as 0.045 (or 4.5% as a decimal).

Then, the probability of an individual not being displeased is:

1 - p = 0.955.

Let X be the number of displeased people in a random sample of 25.

We want to find the probability that at least two people are displeased, which can be expressed as:

P(X ≥ 2) = 1 - P(X < 2)

To calculate P(X < 2), we can use the binomial distribution formula:

[tex]P(X = k) = (^n C_k) \times p^k \times (1 - p)^{n-k}[/tex]

where n is the sample size (25), k is the number of displeased people, and (n choose k) is the binomial coefficient which represents the number of ways to choose k items from a set of n items.

For k = 0, we have:

[tex]P(X = 0) = (^{25}C_ 0) \times 0.045^0 \times 0.955^{25}[/tex]

≈ 0.378

For k = 1, we have:

[tex]P(X = 1) = (^{25}C_1) \times 0.045^1 \times 0.955^{24}[/tex]

≈ 0.42

Therefore,

P(X < 2) = P(X = 0) + P(X = 1) ≈ 0.798.

Finally, we can calculate,

P(X ≥ 2) = 1 - P(X < 2)

= 1 - 0.798

= 0.202.

Thus,

The probability that at least two people will be displeased in a random sample of 25 people is approximately 0.202.

Answer:

The distance across the lake from A to B = 690.7 ft

Step-by-step explanation:

Points A and B are separated by a lake. To find the distance between them, a surveyor locates a point C on land such that

∠CAB=46.5∘. He also measures CA as 312 ft and CB as 527 ft. Find the distance between A and B.

Given

A = 46.5°

a = 527 ft

b = 312 ft

To find; c = ?

Using the sine rule

[a/sin A] = [b/sin B] = [c/sin C]

We first obtain angle B, that is, ∠ABC

[a/sin A] = [b/sin B]

[527/sin 46.5°] = [312/sin B]

sin B = 0.4294

B = 25.43°

Note that: The sum of angles in a triangle = 180°

A + B + C = 180°

46.5° + 25.43° + C = 108.07°

C = 108.07°

We then solve for c now,

[b/sin B] = [c/sin C]

[312/sin 25.43°] = [c/sin 108.07°]

c = 690.745 ft

Hope this Helps!!!

To find the distance across the lake from A to B, use trigonometry and the length of side AC and angle CAB to find the length of side AB.

To find the distance across the lake from point A to point B, we can use trigonometry.

Given that ∠CAB = 46.5°, we can find the distance across the lake by finding the length of side AB in triangle CAB.

Since we know the length of side AC (53 m) and the angle CAB (46.5°), we can use the sine function to find side AB:

AB = AC * sin(CAB) = 53 m * sin(46.5°) = 39.6 m

Therefore, the distance across the lake from point A to point B is approximately 39.6 meters.

Step-by-step explanation:

A given criteria for geometric series of the form [tex]\sum_{n=0}^{\infty} r^n[/tex] is that [tex]|r|<1[/tex]. Other wise, the series diverges. When it converges, we know that

[tex] \sum_{n=0}^\infty r^n = \frac{1}{1-r}[/tex].

So,

a)[tex]\sum_{n=0}^\infty (\frac{3}{2})^n[/tex] diverges since [tex]\frac{3}{2}>1[/tex]

b)[tex]\sum_{n=0}^\infty (\frac{1}{2})^n [/tex]converges since [tex]\frac{1}{2}<1[/tex], and

[tex]\sum_{n=0}^\infty (\frac{1}{2})^n= \frac{1}{1-\frac{1}{2}} = \frac{2}{2-1} = 2[/tex]

c)We can use the series in b) but starting at n=1 instead of n=0. Since they differ only on one term, we know it also converges and

[tex]\sum_{n=1}^{\infty}(\frac{1}{2})^n = \sum_{n=0}^{\infty}(\frac{1}{2})^n-(\frac{1}{2})^0 = 2-1 = 1[/tex].

d)Based on point c, we can easily generalize that if we consider the following difference

[tex]\sum_{n=1}^\infty r^n-\sum_{n=0}^\infty r^n = r^0 = 1[/tex]

So, they differ only by 1 if the series converges.

Final answer:

A divergent geometric series has a common ratio (r) greater than 1. A convergent geometric series has a common ratio (r) between -1 and 1. The sums of geometric series that start at n = 0 and n = 1 are different because the first term is included or omitted.

Explanation:

The questions can be answered as -

(a) A geometric series that diverges is an example where the common ratio (r) is greater than 1. An example of a divergent geometric series is: 2 + 4 + 8 + 16 + ...

(b) A geometric series that converges is an example where the common ratio (r) is between -1 and 1. An example of a convergent geometric series starting at n = 0 is: 1 - 1/2 + 1/4 - 1/8 + ... To find its sum, we can use the formula for the sum of a geometric series: S = a / (1 - r), where S is the sum, a is the first term, and r is the common ratio. Plugging in the values, the sum of this series is 2/3.

(c) A geometric series that starts at n = 1 and converges can have a different sum since the first term is omitted from the calculation. An example of such a series is: 1/2 + 1/4 + 1/8 + 1/16 + ... To find its sum, we use the same formula as in part (b) but with a different first term. In this case, the sum of the series is 1/2.

(d) The sums for a geometric series that starts at n = 0 and n = 1 are different because the first term is included in the sum for n = 0 but omitted in the sum for n = 1.

Answer:

49.5 square feet.

Step-by-step explanation:

6 by 7.5 means 6 x 7.5.

6 x 7.5 = 45

She wants to by 10% extra.

45 is 100% so multiply 45 by 1.1.

45 x 1.1 = 49.5

Olivia's room area is 45 square feet. Considering a 10% extra for waste, she should buy 49.5 square feet of carpet.

To calculate how much carpet Olivia should buy including waste, we first need to figure out the area of her room. The area of a rectangle is found by multiplying the length by the width, so in this case, we multiply 6 feet by 7.5 feet, which equals 45 square feet. Then we factor in the 10 percent extra for waste - which is 4.5 square feet (10% of 45). Adding these together, we get a total of 49.5 square feet. Therefore, Olivia should buy 49.5 square feet of carpet. The correct answer is B. 49.5 square feet.

And we can find this probability using the complement rule and the normal standard distribution and we got:

[tex]P(z>6.302)=1-P(z<6.302)=1-0.99999 \approx 0[/tex]

Given the mean and standard deviation for the number of hacking attacks, the z-score for 600 attacks is about 6.30.

The question asks for the likelihood that the group will suffer an average of more than 600 hacking attacks per year over the next 10 years, given that over the past decade the mean number of hacking attacks experienced by members is 510 per year with a standard deviation of 14.28 attacks. Considering the normal distribution of these hacking attacks, we can calculate this probability by finding the z-score corresponding to 600 attacks and then using the standard normal distribution table to find the probability of exceeding this value.

To calculate the z-score for 600 attacks, we use the formula:

Z = (X - μ) / σ

Where X is the value in question (600 attacks), μ (mu) is the mean (510 attacks), and σ (sigma) is the standard deviation (14.28 attacks). Substituting the given values:

Z = (600 - 510) / 14.28 ≈ 6.30

Looking up a z-score of 6.30 in the standard normal distribution table, we find that the area to the left of this z-score is almost 1, meaning the probability of experiencing more than 600 attacks is extremely small, approaching 0. Thus, it is incredibly unlikely that this group will suffer an average of more than 600 attacks in the next 10 years if nothing changes in their environment.

Answer:

Step-by-step explanation:

You need to subtract the prices of the medium and large from the total

Small = 46.24 - medium -  large

17.50 + 15.75 = 33.75

S = 46.24 - 33.75

S = 12.99

Answer:

x=8

Step-by-step explanation:

We can use the Pythagorean theorem to solve

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

6^2 + x^2 = 10^2

36 + x^2 = 100

Subtract 36 from each side

36-36 +x^2 = 100-36

x^2 = 64

Take the square root of each side

sqrt(x^2) = sqrt(64)

x = 8

Answer:

x = 8

Step-by-step explanation:

According to Pythagorean Theorem

[tex]AB {}^{2} + BC {}^{2} = AC {}^{2} [/tex]

here

[tex]AB = x \\ BC = 6 \\ AC = 10[/tex]

Now,

[tex] {x}^{2} + {6}^{2} = 10 {}^{2} \\ {x}^{2} = {10}^{2} - {6}^{2} \\ x {}^{2} = 100 - 36 \\ {x}^{2} = 64 \\ x = \sqrt{64} \\ x = 8[/tex]

AB = x = 8
