Which of the following equations has no real solutions?
a. 3(x − 4) = 3x − 12
b. 3x − 4 = 3x − 4
c. 3x − 4 = 12x − 4
d. 3(x + 4) = 3(x + 11)

D

Step-by-step explanation: this is because when you simplify D you get 3x+12=3x+33

This is not equal so there is no solution

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

the answer is 5/14.

hope this .
