Please Help!! I will give 50 points and brainliest for the correct answer The question is attached below

B

Step-by-step explanation:

Using the rules of logarithms

logx + logy = log(xy)

x = n ⇒ x =

Given

5 + 12 = 7 , then

(5 × 12) = 7 , that is

60 = 7 , thus

= 60 → B

true

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
