Your cousin bought a used car. He paid a total of $12,755 for the car. The total cost includes: • The list price of the car, x • A 7% sales tax on the list price . Plus $450 in additional fees.
What is the price of the car your cousin bought?
List price:
Answers
Let's use the variable x to represent the list price of the car.
The total cost your cousin paid for the car is the list price plus a 7% sales tax on the list price, plus $450 in additional fees.
We can write this as an equation:
Total cost = List price + 0.07(List price) + 450
We know that the total cost your cousin paid was $12,755, so we can substitute that into the equation:
12,755 = x + 0.07x + 450
Simplifying the right side:
12,755 = 1.07x + 450
Subtracting 450 from both sides:
12,305 = 1.07x
Dividing both sides by 1.07:
x = 11,500
Therefore, the list price of the car your cousin bought was $11,500.
The list price of the car your cousin bought was $11,500.

Let's start by setting up an equation to represent the total cost of the car:
Total cost = List price + 7% of List price + $450
We know that the total cost is $12,755, so we can substitute that in:
$12,755 = List price + 0.07(List price) + $450
Simplifying this equation, we get:
$12,755 = 1.07(List price) + $450
Subtracting $450 from both sides, we get:
$12,305 = 1.07(List price)
Dividing both sides by 1.07, we get:
List price = $11,500
Therefore,
The list price of the car your cousin bought was $11,500.

Callie owns a business and wants to know if the majority of her customers are satisfied. She surveys a random sample of 25 customers, and 17 customers report being satisfied. In a second random sample of 25 customers, 12 customers report being satisfied. The results of the third and fourth surveys of random samples of 25 customers finds 14 and 9 satisfied customers, respectively. Which statement BEST describes the sample mean absolute deviation for this data set?
Answers
Therefore, the statement "The sample mean absolute deviation is likely to be higher for the samples with lower satisfaction rates" would be the BEST description of the MAD for this data set.
To calculate the mean absolute deviation (MAD), we first need to find the mean of each sample.
Sample 1:[tex]17/25 = 0.68[/tex]
Sample 2: [tex]12/25 = 0.48[/tex]
Sample 3: [tex]14/25 = 0.56[/tex]
Sample 4: [tex]9/25 = 0.36[/tex]
Next, we calculate the deviation of each observation from its respective sample mean:
Sample 1: |0.68 - x1|, |0.68 - x2|, ..., |0.68 - x25|
Sample 2: |0.48 - x1|, |0.48 - x2|, ..., |0.48 - x25|
Sample 3: |0.56 - x1|, |0.56 - x2|, ..., |0.56 - x25|
Sample 4: |0.36 - x1|, |0.36 - x2|, ..., |0.36 - x25|
where xi is the satisfaction rating (0 or 1) of the Ith customer in the sample.
The MAD is the average of these deviations:
MAD = (|0.68 - x1| + |0.68 - x2| + ... + |0.36 - x25|)/100
Since we don't know the actual ratings of the customers, we cannot calculate the MAD exactly. However, we can say that the MAD is likely to be higher for samples 2 and 4, which have lower satisfaction rates, compared to samples 1 and 3, which have higher satisfaction rates. Therefore, the statement "The sample mean absolute deviation is likely to be higher for the samples with lower satisfaction rates" would be the BEST description of the MAD for this data set.

Jaxon made 5% of his free throws over the season. If he shot 220 free throws, how many did he make?
Answers
Answer:
Jaxon made 11 free throws over the season.
Step-by-step explanation:
If he made 5% of his free throws, we know that he will make 5% of the total number of free throws he took, which is 220:
We multiply 220 by 0.05, or 5% to find out how many free throws he made:
220*0.05 = 11
After that, we now know that Jaxon made 11 of his free throws out of 220 over the course of the season, or 5%.
suppose the customers arrive at a starbucks shop at an average rate of 1/min. use a poisson process to model the arrival of customers. what is the probability that at least one customer arrives at the shop during a one-minute interval? 0.736 0.368 0.632 0.264
Answers
The probability that at least one customer arrives at the shop during a one-minute interval is 0.632.
Since the arrival of customers at a Starbucks shop can be modeled as a Poisson process with an average rate of 1/min, the probability of exactly k customers arriving in a one-minute interval is given by the Poisson probability mass function:
P(k arrivals) = (λ^k * e^(-λ)) / k!
where λ is the average rate of arrivals (in this case, 1/min), e is the mathematical constant e, and k! is the factorial of k.
To find the probability that at least one customer arrives during a one-minute interval, we can use the complement of the probability that zero customers arrive (i.e., the probability of at least one arrival is 1 minus the probability of zero arrivals).
Thus, the probability of at least one customer arriving during a one-minute interval is:
P(at least one arrival) = 1 - P(0 arrivals)
P(at least one arrival) = 1 - [([tex]1^{0}[/tex] * [tex]e^{-1}[/tex]) / 0!] = 1 - [tex]e^{-1}[/tex] = 0.632
Therefore, the probability that at least one customer arrives at the shop during a one-minute interval is 0.632.

if x is a matrix of centered data with a column for each field in the data and a row for each sample, how can we use matrix operations to compute the covariance matrix of the variables in the data, up to a scalar multiple?
Answers
To compute the covariance matrix of the variables in the data, the "matrix-operation" which should be used is ([tex]X^{t}[/tex] × X)/n.
The "Covariance" matrix is defined as a symmetric and positive semi-definite, with the entries representing the covariance between pairs of variables in the data.
The "diagonal-entries" represent the variances of individual variables, and the off-diagonal entries represent the covariances between pairs of variables.
Step(1) : Compute the transpose of the centered data matrix X, denoted as [tex]X^{t}[/tex]. The "transpose" of a matrix is found by inter-changing its rows and columns.
Step(2) : Compute the "dot-product" of [tex]X^{t}[/tex] with itself, denoted as [tex]X^{t}[/tex] × X.
The dot product of two matrices is computed by multiplying corresponding entries of the matrices and summing them up.
Step(3) : Divide the result obtained in step(2) by the number of samples in the data, denoted as "n", to get the covariance matrix.
This step scales the sum of the products by 1/n, which is equivalent to taking the average.
So, the covariance matrix "C" of variables in "centered-data" matrix X can be expressed as: C = ([tex]X^{t}[/tex] × X)/n.

hat is the maximum speed of a point on the outside of the wheel, 15 cm from the axle?
Answers
It depends on the rotational speed of the wheel. To calculate this speed, we need to know the angular velocity of the wheel.
The maximum speed of a point on the outside of the wheel, 15 cm from the axle, if we assume that the wheel is rotating at a constant rate, we can use the formula v = rω, where v is the speed of the point on the outside of the wheel, r is the radius of the wheel (15 cm in this case), and ω is the angular velocity of the wheel. Therefore, the maximum speed of a point on the outside of the wheel would be directly proportional to the angular velocity of the wheel.
The formula to calculate the maximum linear speed (v) is:
v = ω × r
where v is the linear speed, ω is the angular velocity in radians per second, and r is the distance from the axle (15 cm, or 0.15 meters in this case).
Once you have the angular velocity (ω) of the wheel, you can plug it into the formula and find the maximum speed of a point on the outside of the wheel.

Closure under addition: For any (x₁, x₂) and (y₁, y₂) in S, their sum (x₁ + y₁, 0) is also in S. This axiom holds.Commutativity of addition: For any (x₁, x₂) and (y₁, y₂) in S, (x₁ + y₁, 0) = (y₁ + x₁, 0).

This axiom holds.The Identity element of addition: There exists an element (0, 0) in S such that for any (x₁, x₂) in S, (x₁, x₂) ⊕ (0, 0) = (x₁, x₂). This axiom fails because (x₁, x₂) ⊕ (0, 0) = (x₁, 0) ≠ (x₁, x₂) unless x₂ = 0.Closure under scalar multiplication: For any α in the field of real numbers and (x₁, x₂) in S, α(x₁, x₂) = (αx₁, αx₂) is also in S. This axiom holds.Inverse elements of addition: For any (x₁, x₂) in S, there exists an element (-x₁, 0) in S such that (x₁, x₂) ⊕ (-x₁, 0) = (0, 0). This axiom fails because (-x₁, 0) is not well-defined as the inverse of (x₁, x₂) because (x₁, x₂) ⊕ (-x₁, 0) = (0, 0) holds only if x₂=0.Distributivity of scalar multiplication over vector addition: For any α in the field of real numbers and (x₁, x₂), (y₁, y₂) in S, α ((x₁, x₂) ⊕ (y₁, y₂)) = α(x₁ + y₁, 0) = (αx₁ + αy₁, 0) = α(x₁, x₂) ⊕ α(y₁, y₂).

Label the net for the cylinder. Then find the surface area of the cylinder. Give your answer in terms of π and as a decimal number rounded to the nearest tenth.
Answers
The surface area of the cylinder is approximately 94.2 ft².
What is surface area?Surface area refers to the total area of the external or outer part of an object. It is the sum of the areas of all the individual surfaces or faces of the object. Surface area is typically measured in square units, such as square inches (in²), square feet (ft²), or square meters (m²), depending on the unit of measurement used.
According to the given information:
The surface area of a cylinder is the sum of the lateral surface area (the curved surface) and the area of the two circular bases.
The formula for the lateral surface area of a cylinder is given:
Lateral Surface Area = 2πrh
where r is the radius of the cylinder and h is the height of the cylinder.
Plugging in the given values for the radius (r = 3 ft) and height (h = 2 ft), we can calculate the lateral surface area:
Lateral Surface Area = 2π * 3 * 2 = 12π ft²
The formula for the area of a circle (which represents the bases of the cylinder) is given:
Circle Area = πr²
Plugging in the given value for the radius (r = 3 ft), we can calculate the area of each circular base:
Circle Area = π * 3² = 9π ft²
Since there are two bases in a cylinder, we multiply this by 2 to account for both bases:
2 * Circle Area = 2 * 9π = 18π ft²
Now, we can add the lateral surface area and the area of the two bases to find the total surface area of the cylinder:
Total Surface Area = Lateral Surface Area + 2 * Circle Area
= 12π + 18π
= 30π ft²
As a decimal rounded to the nearest tenth, the surface area of the cylinder is approximately 94.2 ft²

John buys new baseball equipment for $2000. The purchase made is with a credit card that has a 19% APR. John makes a $150 payment monthly. How many months will it take John to pay off the balance?
Answers
It will take John approximately 17 months to pay off the balance.
What is simple interest?
Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
Assuming that John does not use the credit card for any other purchases and that the credit card company uses a simple interest calculation method, we can use the following steps to calculate the number of months it will take John to pay off the balance:
Calculate the monthly interest rate by dividing the annual percentage rate (APR) by 12:
Monthly interest rate = 19% / 12 = 0.01583
Calculate the monthly finance charge by multiplying the outstanding balance by the monthly interest rate:
Monthly finance charge = $2000 x 0.01583 = $31.66
Subtract the monthly payment from the monthly finance charge to get the amount that will be applied to the outstanding balance:
Payment applied to balance = $150 - $31.66 = $118.34
Divide the outstanding balance by the payment applied to balance to get the number of months it will take to pay off the balance:
Number of months to pay off balance = $2000 / $118.34 = 16.9
(rounded up to the nearest whole number)
Therefore, it will take John approximately 17 months to pay off the balance.

All of these ratios are equal to b, and we have shown that there is a constant ratio between consecutive output values.
What is ratio between consecutive output?The common ratio is the ratio that remains constant between successive function output values. The behaviour of a geometric sequence, which is a series of numbers where each term is produced by multiplying the one before it by a set number (the common ratio), depends on the common ratio. The sequence is rising exponentially if the common ratio is bigger than 1. The sequence decreases exponentially if the common ratio is between 0 and 1.
To show that the function form shows a constant ratio we take:
[tex](x+1) / f(x) = (ab^{(x+1)}) / (ab^x) = b[/tex]
Similarly, we have:
[tex]f(x+2) / f(x+1) = (ab^{(x+2)}) / (ab^{(x+1)}) = b[/tex]
Hence, all of these ratios are equal to b, and we have shown that there is a constant ratio between consecutive output values.

in order to maintain accuracy, political polling groups must maintain a certain degree of confidence with a small margin of error. fivethirtyeight is a polling company that wishes to survey a population of people, but maintain a margin of error of 0.05 or less with a 99% confidence level. what is the smallest number of consumers they should survey to guarantee this?
Answers
A minimum sample size of 665 consumers that FiveThirtyEight should survey to guarantee a margin of error of 0.05 or less with a 99% confidence level.
What is the sample size?Sample size refers to the number of observations or individuals included in a study or experiment. It is the number of subjects or units that are selected from a population to be studied. The sample size is an important consideration in statistical analysis, as it can affect the accuracy and generalizability of the results. A larger sample size generally leads to more precise estimates and stronger statistical power, but it can also be more costly and time-consuming to collect and analyze.
According to the given informationTo calculate the minimum sample size required to maintain a margin of error of 0.05 or less with a 99% confidence level, we can use the formula:
n = (Z² * p * (1-p)) / E²
where n is the sample size, Z is the Z-score for the desired confidence level (2.576 for 99% confidence level), p is the estimated proportion of the population that has a certain characteristic (we can use 0.5 for maximum variability), and E is the margin of error.
Plugging in the values, we get:
n = (2.576² * 0.5 * (1-0.5)) / 0.05²
n = 664.3
Rounding up to the nearest whole number, we get a minimum sample size of 665 consumers that FiveThirtyEight should survey to guarantee a margin of error of 0.05 or less with a 99% confidence level.

do less republicans (group a) than democrats (group b) favor the government investing billions of dollars to improve the country's train system? one thousand republicans and one thousand democrats were asked if they favored spending billions to improve the country's train system. how would we write the alternative hypothesis?
Answers
The alternative hypothesis can be written as H₁: pA < pB.
The alternative hypothesis would be that there is a difference in the proportion of Republicans (Group A) and Democrats (Group B) who favor the government investing billions of dollars to improve the country's train system. Expressly, it would state that the proportion of Republicans who favor this investment is less than the proportion of Democrats who favor it:
H₁: pA < pB
where pA denotes the proportion of Republicans who favor the investment and pB denotes the proportion of Democrats who favor the investment.
In the alternative hypothesis, we actually create the relationship between the variables which are being tested in that situation. According to these, we come across the comparison among the variables and how much they differ from each other. The alternative hypothesis is the statement the researcher tries to prove by conducting a statistical analysis.

Answers
The area of Habib's diagram when s = 1/2 is 7.
What is circle?
A circle is a geometric shape that consists of all points in a plane that are equidistant from a fixed point called the center. It can also be defined as the set of points that are a fixed distance (called the radius) away from the center point. The distance around the circle is called its circumference, and the distance across the circle passing through the center is called its diameter.
To find the area of Habib's diagram when s = 1/2, we just need to substitute s = 1/2 into the expression for the area:
Area = 6 + 4s²
Area = 6 + 4(1/2)²
Area = 6 + 4(1/4)
Area = 6 + 1
Area = 7
Therefore, the area of Habib's diagram when s = 1/2 is 7.
