Compute the mean for the following test scores: 72, 86, 91, 25, 37 and 52.

Mean: Average of the numbers in a set of data

To find the mean of the test scores, we need to add up the test scores and divide the sum by the number of tests there are. First, let’s add the test scores.

72 + 86 + 91 + 25 + 37 + 52 = 363

Now, let’s divided 363 by the number of tests there are. In this case, there are six tests so we would divided 363 by 6.

363 ÷ 6 = 60.5

Therefore, the average of these test scores was 60.5.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
