Find p(-4) if p(x) = 3x2 - 4x + 7

p (-4) = 71

Step-by-step explanation:

From the question, x = -4

Therefore, we substitute -4 with x

p(-4) = 3(-4)2 - 4(-4) + 7

3 (-4 × -4) + 4 x 4 + 7 - times - equals +

P(-4)= 3(16) + 16 +7

P(-4)= 48 + 16 +7

P (-4) = 71

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
