What's the value for x makes this equation true 3/5 X-0.5=19

what's the value for x makes this equation true 3/5 X-0.5=19  HERE YOU GO!!

Step-by-step explanation:

-5x - (-7 - 4x) = -2(3x - 4)

-5x + 7+ 4x = -6x + 8

-x + 7= -6x + 8

5x = 8 - 7

5x = 1

x = 1/5

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
