Please help me with this homework equation I don’t understand and need help someone please do step by step

Step-by-step explanation:

f'(x) = 6x-12

in vertex : f'(x) = 0

6x-12 =0 => x=2

f(2) = 3 ( 2² ) -12 (2 ) +1 = -11

vertex ( 2 , -11 )

2? if not the correct answer you might need to provide more information

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
