Solve each equation for y.
2. 38x + 4y = 12

y=  -19/2 x+3

Step-by-step explanation:

38x+4y=12

Step 1: Add -38x to both sides.

38x+4y+−38x=12+−38x

4y=−38x+12

Step 2: Divide both sides by 4

c) yes, because of asa or aas

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
