2 step equation -6+ x/4 = -5

x=4

Step-by-step explanation:

−6+

x

4

=−5

−6+

1

4

x=−5

1

4

x−6=−5

Step 2: Add 6 to both sides.

1/4x−6+6=−5+6

1/4x=1

Step 3: Multiply both sides by 4.

4*(1/4x)=(4)*(1)

x=4

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
