Given data ,
Maria plans to purchase a new work truck. The dealer requires a 10% down payment on the $47,000 vehicle
Maria will finance the rest of the cost with a fixed-rate amortized auto loan at 8.5% annual interest with monthly payments over 5 years
(a)
The required down payment is 10% of $47,000, which is:
Down payment = 0.1 x $47,000 = $4,700
(b)
The amount of the auto loan is the total cost of the truck minus the down payment, which is:
Auto loan = $47,000 - $4,700 = $42,300
(c)
To find the monthly payment, we can use the formula for a fixed-rate amortized loan:
PMT = r(PV) / [1 - (1 + r)^(-n)]
where PMT is the monthly payment, r is the monthly interest rate (which is the annual interest rate divided by 12), PV is the present value of the loan (which is the auto loan amount), and n is the total number of payments (which is the number of years multiplied by 12).
Substituting the given values, we get:
r = 0.085 / 12 = 0.00708333 (monthly interest rate)
PV = $42,300
n = 5 x 12 = 60 (total number of payments)
PMT = 0.00708333($42,300) / [1 - (1 + 0.00708333)^(-60)] = $864.97
Hence , the monthly payment is $864.97

#95141404393
Answer:
3. 255
4. -70
Step-by-step explanation:
3.
For the arithmetic sequence 8, 21, 34, 47, 60, ...
The common difference between consecutive terms is d =(21-8)= 13. Therefore, the nth term of the sequence can be expressed as:
[tex]\bold{a_n = a_1 + (n - 1) * d}[/tex]
where [tex]\bold{a_1}[/tex] is the first term of the sequence,
n is the term number, and d is the common difference.
Substituting [tex]a_1 = 8[/tex] and d = 13, we get:
[tex]a_n = 8 + (n - 1) * 13\\a_n = 13n - 5[/tex]
To find [tex]a_{20}[/tex], substitute n = 20 in the above formula:
[tex]a_{20} = 13(20) - 5\\a_{20}= 255[/tex]
4.
For the arithmetic sequence 6, 2, -2, -6, -10, ...
The common difference between consecutive terms is d =(2-6)= -4. Therefore, the nth term of the sequence can be expressed as:
[tex]\bold{a_n = a_1 + (n - 1) * d}[/tex]
where [tex]a_1[/tex] is the first term of the sequence,
n is the term number, and
d is a common difference.
Substituting [tex]a_1[/tex]= 6 and d = -4, we get:
[tex]a_n = 6 + (n - 1) * (-4)\\a_n = 10 - 4n[/tex]
To find [tex]a_{20}[/tex], substitute n = 20 in the above formula:
[tex]a_{20} = 10 - 4(20)\\a_{20}= -70[/tex]

ANSWER ASAP PLEASE!! THANKS
Answer:
A. If you moved the students from the top 25% in Class 1 into Class 2, the Class 2 median would increase.
Step-by-step explanation:
You want to know the effect of changing or combining class data, given the box plots show two classes with the same median.
We can consider the choices:
A. C2 median would increaseThe medians of the two classes are the same. The maximum value of Class 1 is in the third quartile of Class 2, so the top 25% of Class 1 would be added to the data values currently in the 3rd quartile of Class 2.
In general, one might expect that adding data values above the median will raise the median. Whether this is actually true depends on the details of the distribution and the number of data points added.
It is probably true that the Class 2 median would increase.
B. C1 IQR would increaseThe students who did no homework in Class 1 are the reason for the whisker extending to 0. Removing those from the data set will increase the minimum, likely increasing the value of Q1. This will cause the IQR to be reduced, not increased.
C. Range to 105The range of the combined data sets will be the difference of the largest maximum (70) and the smallest minimum (0). The combined range will be 70, not 105.
D. MedianCombining two data sets with the same median will result in a set of data with the same median. The median will not change, as half the combined data will be above it, and half the combined data will be below it.
Choice A is the only one that makes sense.

A line has a slope of 0 and includes the points (3, t) and (5, -7). What is the value of t?
t =
Answer:
-7
(If you like this answer i would appreciate if u give brainliest but otherwise, i hope this helped ^^)
Step-by-step explanation:
To find the value of t, we can use the formula for the slope of a line:
m = (y2 - y1) / (x2 - x1)
Given that the slope of the line is 0, we have:
0 = (-7 - t) / (5 - 3)
To solve for t, we can cross-multiply:
0 * (5 - 3) = -7 - t
0 = -7 - t
To isolate t, we can add 7 to both sides:
7 = -t
Dividing both sides by -1, we get:
t = -7
Therefore, the value of t is -7.

Prior to June 30, a company has never had any treasury stock transactions. The company repurchased 185 shares of its $1 par common stock on June 30 for $42 per share. On July 20, it reissued 90 of these shares at $46 per share. On August 1, it reissued 70 of the shares at $40 per share. What is the journal entry necessary to record the reissuance of treasury stock on July 20?
On July 20, the company recorded a journal entry debiting cash for $4,140, crediting treasury stock for $3,780, and crediting paid-in capital from treasury stock for $360.
To record the reissuance of treasury stock on July 20, the following journal entry should be made:
Date: July 20
Debit: Cash ($46 * 90) $4,140
Credit: Treasury Stock ($42 * 90) $3,780
Credit: Paid-In Capital from Treasury Stock $360
Explanation:
The debit to Cash represents the amount received from the reissuance of 90 shares at $46 per share, totaling $4,140.
The credit to Treasury Stock reduces the balance of the treasury stock account by the cost of the 90 shares, which is $42 per share, totaling $3,780.
The credit to Paid-In Capital from Treasury Stock accounts for the difference between the cost of the treasury stock and the amount received from its reissuance, which is $46 - $42 = $4 per share, totaling $360.
This journal entry properly reflects the increase in cash from the reissuance of the shares, reduces the treasury stock account balance, and recognizes the gain in paid-in capital resulting from the reissuance at a higher price than the repurchase cost.

Which shows the equation of the line containing the point (3, -2) and having a slope of 2 in slope-intercept form
The equation of the line is y = 2x - 8.
The equation of a line in slope-intercept form (y = mx + b) is determined by the slope (m) and the y-intercept (b).
Given that the point (3, -2) lies on the line and the slope is 2, we can substitute these values into the slope-intercept form to find the y-intercept.
Using the point-slope formula:
y - y1 = m(x - x1)
Substituting (3, -2) and m = 2:
y - (-2) = 2(x - 3)
Simplifying:
y + 2 = 2x - 6
Rearranging to slope-intercept form:
y = 2x - 8
The equation of the line containing the point (3, -2) with a slope of 2 in slope-intercept form is y = 2x - 8.

Correct distribution.
b. With 95% confidence the population mean number of visits per physical therapy patient is between
and
visits.
c. If many groups of 11 randomly selected physical therapy patients are studied, then a different confidence interval would be produced from each group. About
percent of these confidence intervals will contain the true population mean number of visits per patient and about
percent will not contain the true population mean number of visits per patient.
For finding a 95% confidence interval:
a. To compute the confidence interval, use a t distribution with 10 degrees of freedom.b. With 95% confidence, the population mean number of visits per physical therapy patient is between 13.011 and 19.249 visits.c. About 95% of these confidence intervals will contain the true population mean number of visits per patient and about 5% will not contain the true population mean number of visits per patient.How to solve confidence interval?a) The sample mean is x = 16.13.
The sample standard deviation is s = 6.948.
The degrees of freedom are df = 10.
The critical value of t for a 95% confidence interval is t = 2.228.
The margin of error is ME = t × s/√n = 2.228(6.948)/√11 = 4.263.
The 95% confidence interval is x ± ME = 16.13 ± 4.263 = (11.867, 20.393).
b) The 95% confidence interval is (11.867, 20.393).
This means that we are 95% confident that the true population mean number of visits per physical therapy patient is between 11.867 and 20.393 visits.
c) This is because the confidence interval is a range of values that is likely to contain the true population mean. If many samples of the same size are taken from the same population, then about 95% of the confidence intervals from these samples will contain the true population mean.

30 POINTS. Given ABC with coordinates A(-6,1), B(4,1), and C(4,-3). the ordered pair (9,y) is on the line ac. Enter the value of y for this ordered pair.
Answer:
The value of y is -5, so the ordered pair is (9, -5).
Step-by-step explanation:
To determine the value of y for the ordered pair (9, y) on the line AC, we first need to find the equation of the line AC.
To find the slope of the line AC, substitute the points A and C into the slope formula:
[tex]\textsf{Slope}\;(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{y_C-y_A}{x_C-x_A}=\dfrac{-3-1}{4-(-6)}=\dfrac{-4}{10}=-\dfrac{2}{5}[/tex]
To determine the equation of line AC, substitute the found slope and one of the points into the point-slope formula:
[tex]\begin{aligned}y-y_1&=m(x-x_1)\\\\y-1&=-\dfrac{2}{5}(x-(-6)\\\\y-1&=-\dfrac{2}{5}x-\dfrac{12}{5}\\\\y&=-\dfrac{2}{5}x-\dfrac{7}{5} \end{aligned}[/tex]
Now we have found the equation of the line AC, to determine the value of y for the ordered pair (9, y), substitute x = 9 into the equation:
[tex]\begin{aligned}y&=-\dfrac{2}{5}(9)-\dfrac{7}{5}\\\\&=-\dfrac{18}{5}-\dfrac{7}{5}\\\\&=\dfrac{-18-7}{5}\\\\&=\dfrac{-25}{5}\\\\&=-5\end{aligned}[/tex]
Therefore, the value of y for the ordered pair is y = -5.
So the ordered pair is (9, -5).

A contradiction in the given clues and it is not possible to find a valid code with the given information.
The code to open the treasure chest can be determined using a few simple steps.
Firstly, we know that the last digit is half of 18, which is 9.
This means that the code ends with the number 9.
Next, we are given the information that the sum of the two middle digits is 10.
This tells us that the two middle digits must be 4 and 6, as they add up to 10.
Thirdly, we know that the third and fourth digits are the same.
Since we already know that the last digit is 9, this means that the third digit must also be 9.
Finally, we are told that the first digit is double the second digit.
Since we know that the second digit is 4, we can determine that the first digit must be 8.
Therefore, the code to open the treasure chest is 8469.

Find the new balance in each problem.
19. Your balance on May 20 was $189.75,
and you made a $112.45 deposit on
May 22. On May 29, you wrote a $75.68
check, and on June 1, you made an
ATM withdrawal of $50.00.
Answer:
To find the new balance, we'll start with the initial balance on May 20 and then perform the transactions in chronological order.
Step-by-step explanation:
Initial balance on May 20: $189.75
Deposit on May 22: +$112.45
To calculate the balance after the deposit, we add the deposit amount to the initial balance:
New balance after deposit = $189.75 + $112.45 = $302.20
Check written on May 29: -$75.68
To calculate the balance after writing the check, we subtract the check amount from the previous balance:
New balance after check = $302.20 - $75.68 = $226.52
ATM withdrawal on June 1: -$50.00
To calculate the final balance after the ATM withdrawal, we subtract the withdrawal amount from the previous balance:
Final balance after ATM withdrawal = $226.52 - $50.00 = $176.52
Therefore, the new balance after all the transactions is $176.52.

A small rectangular prism has a length of 5 inches, a width of 4 inches, and a volume of 100 cubic inches. A large rectangular prism also has a length of 5 inches and a width of 4 inches, but its volume is 200 cubic inches.
How much taller is the large prism than the small prism?
Write your answer as a whole number or decimal. Do not round.
Answer:
The large prism is 5 inches taller than the small prism
Step-by-step explanation:
We know that the formula for volume of a rectangular prism is
V = lwh, where
V is the volume in cubic unitsl is the length,w is the width,and h is the heightStep 1: We're given the volume, length, and width for both rectangular prisms, but not the height. We can find the height of each rectangular prism by rewriting the volume formula in terms of h (i.e., isolate h), which gives us:
V / (lw) = h
Step 2: To find the height of the small prism, we plug in 100 for V, 5 for l, and 4 for w in the volume formula (in terms of h) and simplify:
100 / (5 * 4) = h
100 / 20 = h
5 inches = height
Optional Confirmation of Step 2:
We can check that our height is correct by plugging in 5 for h in the regular volume formula, with 100 for V, 5 for l, and 4 for w;
100 = 5 * 4 * 5
100 = 20 * 5
100 = 100
Step 3: To find the height of the large prism, we plug in 200 for V, 5 for l, and 4 for w in the volume formula (in terms of h) and simplify:
200 / (5 * 4) = h
200 / 20 = h
10 inches = height
Optional Confirmation of Step 3:
We can check that our height is correct by plugging in 5 for h in the regular volume formula, with 200 for V, 5 for l, and 4 for w;
200 = 5 * 4 * 10
200 = 20 * 10
200 = 200
Step 5:
We now know that the heights of the small and large prism are 5 inches and 10 inches respectivelyWe subtract the small prism's height (5 inches) from the large prism's height (10 inches)This will show how much taller is the large prism than the small prism:10 - 5 = 5 inches taller
