Researchers at the University of Maryland recorded body temperatures from a random sample of 93 healthy adults. They obtained a sample mean of 98.42 ℉ and a standard deviation of 0.65℉. Use this sample data to test the hypothesis that the mean body temperature of all healthy adults is actually less than 98.6℉.

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
