4. 225 is 75% of what number?

scoray [572]

Answer:

300

Step-by-step explanation:

$\frac{225}{x} = \frac{75}{100}$

Since 225 is 75% of a whole, write the proportion such that 225 corresponds to 75% and x, the number we're searching for, corresponds with 100%

Cross multiply to solve and divide by 75 to isolate x:

225 x 100 = 75x

22500 = 75x

300 = x

According to a recent study, 9.3% of high school dropouts are 16- to 17-year-olds. In addition, 6.4% of high school dropou

Finger [1]

Answer:

0.688 or 68.8%

Step-by-step explanation:

Percentage of high school dropouts = P(D) = 9.3% = 0.093

Percentage of high school dropouts who are white = $P(D \cap W)$ = 6.4% = 0.064

We need to find the probability that a randomly selected dropout is white, given that he or she is 16 to 17 years old. This is conditional probability which can be expressed as: P(W | D)

Using the formula of conditional probability, we ca write:

$P(W | D)=\frac{P(W \cap D)}{P(D)}$
