Answer: A. 18
Step-by-step explanation:
Let the smallest number be x
Hence,
x+(x+2)+(x+4)+(x+6)=60
x+x+2+x+4+x+6=60
4x+12=60
4x+12-12=60-12
4x=48
Divide both parts of the equation by 4:

A sample from a population with μ = 40 and σ = 10 has a mean of M = 44. If the sample mean corresponds to a z = 2.00, then how many scores are in the sample?
The number of scores that are in the sample will be 25.
How to calculate the value?From the information, the sample from a population with μ = 40 and σ = 10 has a mean of M = 44 and tthe sample mean corresponds to a z = 2.00.
The number of scores that are in the sample will be:
z = 4 / (10 / ✓n)
2.00 = 4✓n / 10.
4✓n = 20
✓n = 20/4
✓n = 5
n = 5²
n = 25
Therefore, the number of scores that are in the sample will be 25.

If I drove is 357.5 miles in 5 hours and 30 minutes how fast was I driving?
Answer:
65 Miles Per Hour
Step-by-step explanation:
357.5 divided by 5 1/2 equals 357 1/2 divided by 11/2, or 715/2 times 2/11 using reciprocals. Multiply and you get 1430/22 which simplifies down to 65. Therefore you were driving at 65 miles per hour
2. Error Analysis For the figure below, Adam was asked to draw all lines of reflection. His work is shown. What error did Adam make?
The vertical line is correct, but the horizontal line is not.
This is because we can reflect the left half over the vertical line to have it produce the right half, and vice versa.
Unfortunately, the top half is not the same as the bottom half. For instance, the metal part at the bottom is not found at the top. Also the top and bottom shapes don't perfectly match.
what is solve for A K=AP/2
LITERAL EQUATION
The solution for A is given as A = 2K/P
According to the question we have been the formula to find the value of K which is given as follows:
K = AP/2
We need to find the formula to find the value of A from the given above formula. To find the formula we will solve the equation for A which is :
K = AP/2
multiplying both the sides by 2 we get,
K*2 = AP/2 *2
2K = AP
Now dividing both the sides by P we get,
2K/P = AP/P
2k/P = A
or, A = 2K/P
Hence the solution for A is given as A = 2K/P

The costs are as follows: Wheel alignment: $110 Transmission fluid flush: $75 Cabin air filter: $23 What is her total estimate for the repairs?
The total estimate for the repairs when Pam takes her truck in for basic service is $200.
How to illustrate the information?Based on the information given, the costs are as follows:
Wheel alignment: $110 = $100
Transmission fluid flush: $75 = $80
Cabin air filter: $23 = $20
Therefore, the total estimate for the repairs will be:
= $100 + $80 + $20
= $200
Therefore, the total estimate for the repairs when Pam takes her truck in for basic service is $200.

A car bought for £36000 depreciates in
value by 8% each year. Write down a
formula for the value of the car v, after t
years
The value of the car after t years is 36000*0.92^t
A car bought for 36000 euro depreciates in value by 8% each year
we have to find the formula for the value of the car V ,after t years
The Car Depreciation Calculator uses the following formulae
:V = P * (1 - R/100)^n
Where,
V is the value of the car after n years,
P is the purchase amount,
R is the percentage rate of depreciation per annum,
n is the number of years after the purchase.
P = 36000,
R =8%,
n = t
The value of the car after n years, V = P * (1 - R/100)^n
= 36000 * (1 - 8/100)^t
= 36000 * (1 - 0.08)^t
= 36000 * (0.92)^t
= 36000 * 0.92^t
Hence, The value of the car after t years is 36000*0.92^t

Janet just graduated from college, has a job she's scheduled to begin in 3 months and has decided to treat herself to 6 weeks of travel across South America before she buckles down and starts working full-time. To do the trip, she's thinking of applying for a personal loan of $3500, and the bank she uses for her checking and savings account has offered her an interest rate of 24%. She has a goal of paying off the trip within two years. PLEASE HELP ASAP!!
3) By the time Janet pays off the loan, the total interest she would have paid is D. $941.17.
4) By the time Jane pays off the loan, the total cost of her tip is B. $4,441.17.
5) The equation to find the new balance after each month's payment is D. New balance = Previous balance - Total monthly payment.
How is the monthly payment computed?The monthly payments can be computed by first computing the total payments (future value of the loan). Then, the above figure is divided by the number of periods.
For instance, the total cost of Janet's trip is $4,441.17. The payments are made for 24 months. Dividing $4,441.17 by 24 gives $941.17.
Data and Calculations:N (# of periods) = 24 months (2 x 12)
I/Y (Interest per year) = 24%
PV (Present Value) = $3,500
FV (Future Value) = $0
Results:
PMT = $185.05
Sum of all periodic payments = $4,441.17 ($3,500 + $941.17)
Total Interest = $941.17
Thus, Janet would have spent $4,441.17 to obtain a loan of $3,500 for her trip at 24% interest with 24 months for repayment.

Scaling is a resizing process. To draw a scaled size of a figure, we need to multiply all of the lengths by a scale factor. When drawing scale copies, we need to remember to the aspect ratio.
What is scaling?
Scaling process defines the resizing the image by increasing or decreasing the size of the image. It enhanced the image by the method called magnification. The magnification of the image depends on the resolution which defines the aspect ratio.
This process makes the image smaller by scaling down or bigger by scaling up. It play a vital role in computer graphics as well as vision based algorithms.

Frank camped and hiked for three days. He hiked around three of the lakes.
He estimated his hiking distance to be more than 35 miles but less than 40
miles. Which three lakes did Frank hike? explain your answer
a = 6.51
b = 8.74
c = 21.25
d = 18.68
e = 15.33
The three lakes that Frank walked were Lakes A, B, and C. This may be deduced from the distances between the lakes as well as the total distance that Frank traveled, which was more than 35 miles but less than 40 miles.
How do locate the lakes when hiking?You may determine which lakes Frank walked to by combining a total of three lakes from the set of lakes provided in the puzzle.
Assuming Frank hiked Lakes A, B, and C, the distance is;
= 6.51 + 8.74 + 21.25
= 36.5 miles
Lakes A, B, and D:
= 6.51 + 8.74 + 18.68
= 33.93 miles
Lakes A, B, and E:
= 6.51 + 8.74 + 15.33
= 30.58 miles
It can be observed that Lakes A, B, and C are the only ones that meet the requirement of having a distance of fewer than 40 miles but more than 35 miles.
The following questions should be asked next:
Lakes: a = 6.51
b = 8.74
c = 21.25
d = 18.68
