6) 9x - 7y = -4
18x - 14 y = 10
A) (8, -1)
C) (-8,-8)
B) (-8,-1)
D) No solution

D). No solution

Step-by-step explanation:

9x - 7y = -4

18x - 14 y = 10

9x - 7y = 5

9x - 7y = -4

9x - 7y = 5

--

0 = -9

the naturalist literary movement was an extension of the realist literary movement, a movement that strove to portray life as it really was hope it

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
