The coefficient of variation for the final exam is higher than that for the midterm exam, indicating that the scores on the final exam are more dispersed relative to the mean than the scores on the midterm exam.

To compare the degree of dispersion in the two distributions, we can calculate the coefficient of variation (CV) for each exam:

CV = (standard deviation / mean) x 100%

For the midterm exam:

CV = (10 / 75) x 100% = 13.33%

For the final exam:

CV = (15 / 55) x 100% = 27.27%

To determine which class had the greatest amount of variation in exam scores relative to their means, we can compare the coefficient of variation for the two classes. Since the CV for the final exam is higher than that for the midterm exam, we can conclude that the final exam had a greater amount of variation in exam scores relative to the mean for the class than the midterm exam.

Answer:

To calculate the time it will take to pay off the account, we can use the formula for the future value of an annuity:

PV = PMT * ((1 - (1 + r)^(-n)) / r)

Where:

PV = Present value (current balance)

PMT = Payment amount per period

r = Interest rate per period

n = Number of periods

In this case:

PV = $14,790

PMT = $570

r = 0.0097 (0.97% expressed as a decimal)

n = ?

Plugging in the values, we can solve for n:

14,790 = 570 * ((1 - (1 + 0.0097)^(-n)) / 0.0097)

Let's solve this equation to find the value of n:

((1 + 0.0097)^(-n)) = 1 - (14,790 * 0.0097) / 570

((1 + 0.0097)^(-n)) = 0.9742105

Taking the logarithm of both sides:

-n * log(1.0097) = log(0.9742105)

n = log(0.9742105) / log(1.0097)

Using a calculator, we find that n is approximately 28.56.

Therefore, it will take approximately 28.56 months (or 28 months and 17 days) to pay off the account.

Step-by-step explanation:

The probability that a student studied for exactly 4 hours rounded to the nearest hundredth is C. 0.26.

The concept that will be used here is probability. From the question the first column of a table serves as the amount of hours a student spent studying math,  while the  second column can be seen as the total number of pupils.

We can see from the second column's total  which is  35. We can see that just only 9 of them spent 5 hours  in the process of going over their arithmetic.

Then the likelihood that a student studied for four hours  can be known which can be calculated as :

= [9/35]

a. The y-intercept of the graph is 35,000, which represents the original purchase price of the car. Therefore, the car was purchased for $35,000.

b. We can see from the graph that the car's value becomes 0 after 9 years. Therefore, the car totally depreciates after 9 years.

c. The equation of a straight line can be written as y = mx + b, where m is the slope and b is the y-intercept. The slope of the graph is the rate of depreciation, which is -4000. The y-intercept is the original price of the car, 35000.

So the equation of the straight line depreciation graph is: y = -4000x + 35000

This equation represents the value of the car, where y is the value of the car (in dollars) x is the number of years since the car was purchased and -4000 is the rate of depreciation and 35000 is the original price of the car.

Step-by-step explanation:

There are 4 cards in a deck of 52 cards that has a face value of 3. That means that the other 48 cards don't have a face value of 3. Therefore, the probability of picking a card of this deck that doesn't have a face value of 3 is

\(P =\dfrac{48}{52} = 0.92\)

The probability that the card does not have a face value of 3 is 0.92.

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that the card does not have a face value of 3 - (total cards in a deck of cards - number of cards with a face value of 3) / total cards in a deck of cards

(52 - 4) / 52

As he rolls the dough, if length is increasing at a rate of 0.5 cm/sec, the rate at which the radius is changing when the radius is 1cm and the length is 5cm will be -0.05 cm/sec using the concept of increasing or decreasing functions.

As per the question statement, if dough is in form of a cylinder and its length is increasing at a rate of 0.5 cm/sec, we have to find the rate at which the radius is changing when the radius is 1cm and the length is 5cm.

Volume V = πr^2h, where 'r' is the radius and 'h' is the length

dV/dt = πr^2*(dh/dt) + h*2πr*(dr/dt) [Derivation wrt 't']

dV/dt = 0, as quantity of dough is same.

so at r = 1cm and h = 5cm

0 = π(1^2)*(0.5) + 5*2π*1(dr/dt)

5*2π*1(dr/dt) = -π(1^2)*(0.5)

10π*(dr/dt) = -π*0.5

(dr/dt) =  -0.05 cm/sec

Hence, as he rolls the dough, if length is increasing at a rate of 0.5 cm/sec, the rate at which the radius is changing when the radius is 1cm and the length is 5cm will be -0.05 cm/sec using the concept of increasing or decreasing functions.

The maximum profit the florist will earn from selling celebration bouquets is $725.

The florist will break-even after one-dollar decreases when her profit is zero. From the graph, this occurs at x = 10. So the florist will break-even after 10 one-dollar decreases.

The interval of the number of one-dollar decreases for which the florist makes a profit from celebration bouquets is (0, 10). This is because the profit is positive for values of x between 0 and 10, and becomes negative after 10.

The scale factor of the dilation is 4.

We are given that;

The equation of line −11x=4y+4

Now,

The center of dilation is the origin (0, 0). The line given by −11x = 4y + 4 can be rewritten as y = −11/4 x − 1. This means that it passes through the points (0, −1) and (−4, 0). The image of the line after dilation is given by −11x − 4y = 16, which can be rewritten as y = −11/4 x − 4. This means that it passes through the points (0, −4) and (−16, 0).

To find the scale factor, we can use any pair of corresponding points. For example, let’s use (0, −1) and (0, −4). The distance from the center of dilation to (0, −1) is 1 unit. The distance from the center of dilation to (0, −4) is 4 units. Therefore, the scale factor is 4/1 = 4.

Using the normal distribution, it is found that the z-scores are:

a) z = -1.5

b) z = 1.9

c) z = 0

In normal distribution with mean 'μ' and the standard deviation 'σ', the z-score of a measure X is given by:

z = x-μ/σ

It measures how many standard deviations the measure is from the mean, either above the mean(positive z-score), or below(negative z-score).

For first blank: 1.5 standard deviations below the mean, hence z = -1.5.

For second blank: 1.9 standard deviations below the mean, hence z = 1.9.

The probability of snow given that the temperature is below 32°F is approximately 33.3%. Hence, the correct answer is (A) 33.3%.

To find the probability of snow given that the temperature is below 32°F, we can use conditional probability. The conditional probability of an event A given event B is denoted as P(A|B) and is calculated as the probability of both events A and B occurring divided by the probability of event B occurring.

In this case, event A represents snow and event B represents the temperature being below 32°F.

We are given the following probabilities:

P(snow) = 50%

P(temperature below 32°F) = 60%

P(snow and temperature below 32°F) = 20%

To find P(snow temperature below 32°F), we can use the formula:

P(snow temperature below 32°F) = P(snow and temperature below 32°F) / P(temperature below 32°F)

Substituting the given probabilities, we have:

P(snow temperature below 32°F) = 0.20 / 0.60

P(snow temperature below 32°F) = 1/3

Converting this fraction to a percentage, we get:

P(snow temperature below 32°F) ≈ 33.3%

Therefore, the probability of snow given that the temperature is below 32°F is approximately 33.3%. Hence, the correct answer is (A) 33.3%.
