Answer:

0.25s + 6.2

Step-by-step explanation:

Discount on sale expression : 1/4(s + 24.80)

Retail price of shoe = s

Retail price of hats = 24.80

From expression, we can conclude that there is a ; 1/4 = 0.25 = (0.25 * 100%) = 25% discount on each item ;

Hence, discount expression could be written as :

0.25s + 0.25(24.80)

0.25s + 6.2

Answer:

Use the equation y=mx+b

Step-by-step explanation:

So you know how to get the slop, which is awesome

Now to get y all you have to do is use the equation:

y=mx+b

m being slop

b being y- intercept in this case being 2

so you have y=-2x+2

all you have to do is insert different x values and solve the equation for y and see if they match up together in any of the tables

The volumes of the solids generated by rotating the given region around the given axis of rotation are 200π, 120π, 120π, and 80π, respectively.

Pappus' Theorem states that the volume of a solid generated by rotating a planar region about an external axis is equal to the product of the area of the region and the distance traveled by the centroid of the region during the rotation.

We can apply this theorem to find the volume of the solids generated by rotating the given region around the given axis of rotation.

a. When the region R is rotated around the x-axis, the distance traveled by the centroid is 2π(5) = 10π. Therefore, the volume of the solid is 20 × 10π = 200π.

b. When the region R is rotated around the y-axis, the distance traveled by the centroid is 2π(3) = 6π. Therefore, the volume of the solid is 20 × 6π = 120π.

c. When the region R is rotated around x=2, the distance traveled by the centroid is 2π(5-2) = 6π. Therefore, the volume of the solid is 20 × 6π = 120π.

d. When the region R is rotated around y=1, the distance traveled by the centroid is 2π(3-1) = 4π. Therefore, the volume of the solid is 20 × 4π = 80π.

Therefore,the solids generated by rotating the specified region around the specified axis of rotation have volumes of 200π, 120π, 120π, and 80π,  respectively.

Step-by-step explanation:

The probability that the total is less than 11 when a 1) pair of dice is tossed is 1. 2) The number of permutations of 8 teams taken 5 at a time can be represented as P(8, 5) and can be calculated as 8!/(8-5)! = 8!/3! = (8 * 7 * 6 * 5 * 4)/(5 * 4 * 3 * 2 * 1) = 56.

When two dice are tossed, the maximum possible sum is 12 (when both dice show 6). Since we are interested in the probability that the total is less than 11, it means we are considering all the possible outcomes where the sum of the dice is less than 11.

We can analyze all the possible outcomes:

Summing up all the possible outcomes, we find that there are 36 possible outcomes when tossing a pair of dice. Since all the outcomes have a sum less than 11, the probability of getting a sum less than 11 is 1.

To find the number of different Top 5 Ranking lists possible with 8 college basketball teams, we need to calculate the number of permutations of the teams taken 5 at a time.

This can be done using the formula for permutations: P(n, r) = n!/(n-r)!, where n is the total number of items and r is the number of items being selected.

In this case, we have 8 teams and we want to select 5 teams. So, P(8, 5) = 8!/(8-5)! = 8!/3! = (8 * 7 * 6 * 5 * 4)/(5 * 4 * 3 * 2 * 1) = 56.

Therefore, there are 56 different Top 5 Ranking lists possible.

The approximate total amount Valerie will pay for her new car is $38,287.

How much will Valerie pay in total for her new car?

To calculate how much Valerie will pay in total for her new car, we need to consider several factors.

First, let's determine the trade-in value of her 2006 Hyundai Sonata. Since the car is in good condition, Valerie will receive 87.5% of the listed trade-in price for that year, which is $6,784. Therefore, the trade-in value is approximately $5,938.80 ($6,784 * 0.875).

Now, let's calculate the total cost of the new car. The list price is $32,495, and Valerie plans to make a down payment of $1,877. Thus, the remaining amount to be financed is $32,495 - $1,877 - $5,938.80 = $24,679.20.

Next, let's consider the interest on the financing. The interest rate is 8.64% per year, compounded monthly. Over five years, this amounts to 60 monthly payments. Using an amortization formula, we can determine that the monthly payment is approximately $516.27.

Additionally, Valerie will have to pay sales tax, vehicle registration fee, and documentation fee. The sales tax is 8.23% of the total cost, which is ($24,679.20 + $2,243) * 0.0823 = $2,329.48. The vehicle registration fee is $2,243, and the documentation fee is $314. The total additional fees amount to $2,329.48 + $2,243 + $314 = $4,886.48.

Finally, to calculate the total amount Valerie will pay, we add the down payment, monthly payments, trade-in value reduction, and additional fees: $1,877 + (60 * $516.27) + $5,938.80 + $4,886.48 = $38,285.88.

Rounding to the nearest cent, Valerie will pay approximately $38,286 for her new car. Thus, the correct answer is option c: $38,287.

In statistics, the mean is a measure of central tendency and is calculated by adding up all the values in a data set and dividing the sum by the number of values. It is also known as the arithmetic average.

To determine whether the fourth album's data set is very different from each of the others, we need to compare its mean and mean absolute deviation to those of the other data sets.

If the mean length of the fourth album is significantly different from the mean length of the other albums, then the data sets are different. If the mean absolute deviation of the fourth album is significantly different from the mean absolute deviation of the other albums, then the data sets are also different.

what is  absolute deviation?

In statistics, the absolute deviation is a measure of how much the data values deviate from the mean. It is the absolute value of the difference between each data value and the mean.

The formula for the absolute deviation is:

Absolute deviation = | x - mean |

Random variables that can take on any value in some interval are called continuous random variables.

A continuous random variable is defined over a continuous range of values and can take on any value within that range. This is in contrast to discrete random variables, which can only take on a finite or countably infinite set of distinct values.

The probability distribution of a continuous random variable is described by a probability density function (PDF), which specifies the likelihood of the random variable taking on different values. The area under the PDF curve within a given interval represents the probability of the random variable falling within that interval.

Examples of continuous random variables include the height of a person, the time it takes for an event to occur, or the temperature at a specific location.

The principal of $56,300 invested at a 4% simple interest rate would be worth more than the principal itself in approximately 20.7 years.

On the other hand, the principal of $6,300 invested at a 4% simple interest rate would be worth more than the annual interest in approximately 23.1 years.

For the first scenario, we need to calculate the time it takes for the principal to accumulate an amount greater than itself. With a 4% simple interest rate, the interest earned each year is 4% of the principal. So, the interest earned per year can be calculated as 0.04 multiplied by $56,300, which is $2,252. To find the number of years it takes for the interest to exceed the principal, we divide the principal by the annual interest: $56,300 divided by $2,252 equals approximately 24.999. Therefore, it would take approximately 20.7 years for the principal of $56,300 to be worth more than itself.

For the second scenario, we want to determine when the annual interest earned exceeds the principal of $6,300. Again, the interest earned per year is 4% of the principal, which is $252. To find the number of years it takes for the annual interest to surpass the principal, we divide the principal by the annual interest: $6,300 divided by $252 equals approximately 25. Therefore, it would take approximately 23.1 years for the annual interest of the principal of $6,300 to be worth more than the principal itself.

The proportion of a normal distribution located between z = .50 and z = -.50 will be 38.2%.

We have,

A normal distribution located between z = 0.50 and z = -0.50,

So,

Now,

From the Z-score table,

We get,

The Probability corresponding to the Z score of -0.50,

i.e.

P(-0.50 < X < 0) = 0.191,

And,

The Probability corresponding to the Z score of -0.50,

i.e.

P(0 < X < 0.50) = 0.191,

Now,

The proportion of a normal distribution,

P(Z₁ < X < Z₂) = P(Z₁ < X < 0) + P(0 < X < Z₂)

Now,

Putting values,

i.e.

P(-0.50 < X < 0.50) = P(-0.50 < X < 0) + P(0 < X < 0.50)

Now,

Again putting values,

We get,

P(-0.50 < X < 0.50) = 0.191 + 0.191

On solving we get,

P(-0.50 < X < 0.50) = 0.382

So,

We can write as,

P(-0.50 < X < 0.50) = 38.2%

The correct answer is False because, If the sample size is large enough (n greater than or equal to 30) the sampling distribution is approximately normal regardless of the shape of the population.

The sample fraction, often called the "p-hat", is the ratio of the number of sample successes to the size of the sample. The standard deviation of (p) decreases as the sample size n increases. This is because n is included in the denominator of the standard deviation formula. That is, (p has) has fewer variables for larger samples. The P-hat (must be a lowercase p with a caret (^) circumflex) indicates the percentage of the sample (this is the x-bar, the average of the samples).

A p-hat (proportion) sampling distribution is a collection of equal-sized repeated sample proportions drawn from the same population to represent it. According to the central limit theorem, the sampling distribution of p-hat is approximately normally distributed for large sample sizes.
