Answer:
17.11%
Step-by-step explanation:
since 43.2 months is the mean, and the standard deviation is 7.7 months
that means if we take the z score:
z=(36-43.2)/7.7
now that we know how many standard deviations you are away from the mean: -0.9351
using the zscore table you can find the proportion, or you can use the calculator if you have one that can do that.
you get 0.1711 which in percentages is 17.11%

Compound interest</h3>
Compound interest is given by:
where A is the amount after t years, P is initial amount, r is the rate and n is the times compounded per period
Given that n = 1, r = 9% = 0.09, A = $7500 t = 11. Hence:
Mr. and Mrs. Bailey need to invest $2906.50 so as to send their son to college.

Answer:
6 x 4 = 24, 24 divided by 2 = 12(area of 1 triangle)
12 x 2(two triangles) = 24
5 x 6 = 30(area of 1 slanted rectangle)
30 x 2(two rectangles) = 60
6 x 6 = 36(area of bottom square)
Add all given AREAS:
24 + 60 + 60 = 144 mm2 is your answer.
