According to a recent study, 8.6% of high school dropouts are 16- to 17-year-olds. in addition, 6.3% of high school dropouts are white 16- to 17-year-olds. what is the probability that a randomly selected dropout is white, given that he or she is 16 to 17 years old? g

The formula for conditional probability is

... P(A|B) = P(A&B)/P(B)

Filling in the given numbers ...

... P(white | 16 or 17) = P(whiite & (16 or 17)) / P(16 or 17)

... = 6.3% / 8.6% ≈ 0.7326

correct answers below:

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
