A car is purchased for $35,000. The owner finances the car at an interest rate of 4.6%, continuously compounded, for 6 years. What is the monthly payment on the car? Group of answer choices $640.62 $46,124.68 $35,046.00 $743.95
The monthly payment on the car is approximately $640.62. The correct option is A
To solve this problemThe formula for the monthly payment on a continuously compounded loan can be expressed as:
P = (r * A) / (1 - (1 + r)^(-n))
Where
P is the monthly payment r is the yearly interest rateA is the principal (i.e., the original amount borrowed) n is the number of payments (i.e., the number of years multiplied by 12)r is the annual interest rate (stated as a decimal and constantly compounded)Plugging in the given values, we get:
P = (0.046 * 35000) / (1 - (1 + 0.046/12)^(-6*12))
P ≈ $640.62
Therefore, the monthly payment on the car is approximately $640.62.

How many solutions does the equation 5x - 8 = 5x + 17 have?
Step-by-step explanation:
if you made no typo, then the equation is
5x - 8 = 5x + 17
subtract 5x from both sides gives us
-8 = 17
and that is never true, no matter what value we use for x.
therefore, there are 0 solutions.
make up a sample of size n = 10 for which the average is −9 (note the (−) sign). not all 10 numbers should be identical.
This sample has an average of −9: −15, −12, −10, −9, −9, −9, −9, −8, −5, −4.
To make up a sample of size n = 10 for which the average is −9, we can use the following formula:
Average = (Sum of all values) / (Number of values)
If we rearrange this formula to solve for the sum of all values, we get:
Sum of all values = Average × Number of values
Plugging in the values for the average and number of values, we get:
Sum of all values = (−9) × 10 = −90
Now, we can come up with any 10 numbers that add up to −90. Here is one possible sample:
−15, −12, −10, −9, −9, −9, −9, −8, −5, −4
To check our work, we can add up these 10 numbers and divide by 10 to find the average:
(−15 + −12 + −10 + −9 + −9 + −9 + −9 + −8 + −5 + −4) / 10 = −90 / 10 = −9
Note that there are many other possible samples that would also have an average of −9, as long as the sum of all 10 numbers is −90.

the weights of certain machine components are normally distributed with a mean of 5.12 ounces and a standard deviation of 0.07 ounces. find the two weights that separate the top 5% and the bottom 5% . these weights could serve as limits used to identify which components should be rejected. round your answer to the nearest hundredth, if necessary.
The weight that separates the bottom 5% is approximately 5.02 ounces.
To find the weights that separate the top 5% and the bottom 5%, we need to use the z-score formula and the standard normal distribution table.
First, let's find the z-score for the top 5%. Using the standard normal distribution table, we find that the z-score for the top 5% is approximately 1.645.
Next, we can use the formula z = (x - μ) / σ, where z is the z-score, x is the weight we're trying to find, μ is the mean, and σ is the standard deviation.
For the top 5%, we have:
1.645 = (x - 5.12) / 0.07
Solving for x, we get:
x = 5.12 + 1.645 * 0.07
x ≈ 5.22 ounces
Therefore, the weight that separates the top 5% is approximately 5.22 ounces.
To find the weight that separates the bottom 5%, we use the same process but with a negative z-score. The z-score for the bottom 5% is approximately -1.645.
-1.645 = (x - 5.12) / 0.07
Solving for x, we get:
x = 5.12 - 1.645 * 0.07
x ≈ 5.02 ounces
Therefore, the weight that separates the bottom 5% is approximately 5.02 ounces.
These weights could serve as limits used to identify which components should be rejected. Any component with a weight less than 5.02 ounces or greater than 5.22 ounces should be rejected.

3) A moving target at a police academy target range can be hit 88% of the time by a particular individual. Suppose that as part of a training exercise, eight shots are taken at a moving target. a) What 3 characteristics of this scenario indicate that you are working with Bernoulli trials? b) What is the probability of hitting the 6
th
target (Hint: think of this as a single trial)? c) What is the probability that the first time hitting the target is not until the 4 th shot?
a. The probability of success (hitting the target) is constant for each trial (88% or 0.88).
b. The probability of hitting the 6th target is:
P(X = 1) = C(1, 1) * 0.88^1 * (1 - 0.88)^(1 - 1) = 0.88
c. Using the binomial probability formula as before, with p = 0.88 and n = 3:
P(X = 1) = C(3, 1) * 0.88^1 * (1 - 0.88)^(3 - 1)
P(X = 2) = C(3, 2) * 0.88^2 * (1 - 0.88)^(3 - 2)
P(X = 3) = C(3, 3) * 0.88^3 * (1 - 0.88)^(3 - 3)
a) The three characteristics of this scenario that indicate we are working with Bernoulli trials are:
The experiment consists of a fixed number of trials (eight shots).
Each trial (shot) has two possible outcomes: hitting the target or missing the target.
The probability of success (hitting the target) is constant for each trial (88% or 0.88).
b) To find the probability of hitting the 6th target (considered as a single trial), we can use the binomial probability formula:
P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)
where:
P(X = k) is the probability of getting exactly k successes,
C(n, k) is the binomial coefficient or number of ways to choose k successes out of n trials,
p is the probability of success in a single trial, and
n is the total number of trials.
In this case, k = 1 (hitting the target once), p = 0.88, and n = 1. Therefore, the probability of hitting the 6th target is:
P(X = 1) = C(1, 1) * 0.88^1 * (1 - 0.88)^(1 - 1) = 0.88
c) To find the probability that the first time hitting the target is not until the 4th shot, we need to consider the complementary event. The complementary event is hitting the target before the 4th shot.
P(not hitting until the 4th shot) = P(hitting on the 4th shot or later) = 1 - P(hitting on or before the 3rd shot)
The probability of hitting on or before the 3rd shot is the sum of the probabilities of hitting on the 1st, 2nd, and 3rd shots:
P(hitting on or before the 3rd shot) = P(X ≤ 3) = P(X = 1) + P(X = 2) + P(X = 3)
Using the binomial probability formula as before, with p = 0.88 and n = 3:
P(X = 1) = C(3, 1) * 0.88^1 * (1 - 0.88)^(3 - 1)
P(X = 2) = C(3, 2) * 0.88^2 * (1 - 0.88)^(3 - 2)
P(X = 3) = C(3, 3) * 0.88^3 * (1 - 0.88)^(3 - 3)
Calculate these probabilities and sum them up to find P(hitting on or before the 3rd shot), and then subtract from 1 to find the desired probability.

a photo dimensions are 9 inches by 12 inches, what is the new dimensions with a scale factor of 3/4?
Let's suppose the original length and width of the photo is L and W, respectively. As given, the original dimensions are 9 inches by 12 inches. L = 9 inches and W = 12 inches
The given scale factor is 3/4 and we have to find the new dimensions of the photo.So, the new length of the photo will be 3/4 of the original length and the new width will be 3/4 of the original width.New length of the photo = (3/4)LNew width of the photo = (3/4)W
Substituting the given values of L and W, we get;
New length of the photo = (3/4)(9) inches = 6.75 inches
New width of the photo = (3/4)(12) inches = 9 inches
Therefore, the new dimensions of the photo with a scale factor of 3/4 are 6.75 inches by 9 inches
Thus, the dimensions of the photo with a scale factor of 3/4 are 6.75 inches by 9 inches.

Solve the following using Substitution method
2x – 5y = -13
3x + 4y = 15
\( \huge \boxed{\mathfrak{Question} \downarrow}\)
Solve the following using Substitution method
2x – 5y = -13
3x + 4y = 15
\( \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}\)
\(\left. \begin{array} { l } { 2 x - 5 y = - 13 } \\ { 3 x + 4 y = 15 } \end{array} \right.\)
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.\(2x-5y=-13, \: 3x+4y=15 \)
Choose one of the equations and solve it for x by isolating x on the left-hand side of the equal sign. I'm choosing the 1st equation for now.\(2x-5y=-13 \)
Add 5y to both sides of the equation.\(2x=5y-13 \)
Divide both sides by 2.\(x=\frac{1}{2}\left(5y-13\right) \\ \)
Multiply \(\frac{1}{2}\\\) times 5y - 13.\(x=\frac{5}{2}y-\frac{13}{2} \\ \)
Substitute \(\frac{5y-13}{2}\\\) for x in the other equation, 3x + 4y = 15.\(3\left(\frac{5}{2}y-\frac{13}{2}\right)+4y=15 \\ \)
Multiply 3 times \(\frac{5y-13}{2}\\\).\(\frac{15}{2}y-\frac{39}{2}+4y=15 \\ \)
Add \(\frac{15y}{2} \\\) to 4y.\(\frac{23}{2}y-\frac{39}{2}=15 \\ \)
Add \(\frac{39}{2}\\\) to both sides of the equation.\(\frac{23}{2}y=\frac{69}{2} \\ \)
Divide both sides of the equation by 23/2, which is the same as multiplying both sides by the reciprocal of the fraction.\(\large \underline{ \underline{ \sf \: y=3 }}\)
Substitute 3 for y in \(x=\frac{5}{2}y-\frac{13}{2}\\\). Because the resulting equation contains only one variable, you can solve for x directly.\(x=\frac{5}{2}\times 3-\frac{13}{2} \\ \)
Multiply 5/2 times 3.\(x=\frac{15-13}{2} \\ \)
Add \(-\frac{13}{2}\\\) to \(\frac{15}{2}\\\) by finding a common denominator and adding the numerators. Then reduce the fraction to its lowest terms if possible.\( \large\underline{ \underline{ \sf \: x=1 }}\)
The system is now solved. The value of x & y will be 1 & 3 respectively.\( \huge\boxed{ \boxed{\bf \: x=1, \: y=3 }}\)

The arc measures x, y and z which subtends angles at the circle center are 20°, 180° and 160° respectively.
What is angle subtended by an arcThe angle subtended by an arc of a circle at it's center is twice the angle it substends anywhere on the circles circumference. Also the arc measure and the angle it subtends at the center of the circle are directly proportional.
arc x subtends the angle 20° at the center of the circle so x = 20°
arc y subtends the half of the circle angle at the center which is 180° so y = 180°
arc z subtends the angle 180° - 20° at the circle center, so z = 160°

eight children sit together at story time. seven children sit in a circle and one child sits in the middle to tell the story. in how many different ways can the children sit? (two seatings are considered identical if the same child is in the middle in both and each child on the outside has the same child on his or her right in both seatings.)
There are 8208 different ways that the children can sit.
There are 8 children in total, so we first need to choose one of them to sit in the middle. This can be done in 8 ways.
Once the child in the middle has been chosen, the remaining 7 children can sit in a circle around them. There are (7-1)! = 6! = 720 ways to arrange 7 children in a circle. However, due to the condition that "two seatings are considered identical if the same child is in the middle in both and each child on the outside has the same child on his or her right in both seatings", we need to divide by 7 to account for the fact that there are 7 equivalent circular arrangements.
Therefore, the total number of different ways that the children can sit is:
