HELP NOW Each of three friends flips a coin 36 times 36 times. Angel records tail 20 times Michael records tails 17 times Fernada records tails 23 times a. Find the relative frequency with which each friend record "Tails"

b. Which friend has a relative frequency that is closest to the theoretical probability of flipping "tails" 36 times

A.) 60

B.) Fernada

Step-by-step explanation:

A.) you would add up all the friends records (20 + 17 = 37, 37+ 23 = 60).

B.) you would see if anybody was close to 36 and Fernada counted 23 and they would be the closes.

the answer is d

step-by-step explanation:

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
