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:

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

Using the values, we get:

P( W | D) = $\frac{0.064}{0.093} = 0.688$

Therefore, the probability that a randomly selected dropout is white, given that he or she is 16 to 17 years old is 0.688 or 68.8%

Jacks mother gave him 50 chocolates to give to his friends at his birthday party. He gave 3 chocolates to each of his friends an

nevsk [136]

16

Explanation:

Okay so Jack started with 50 chocolates, and ended with 2.
The simple way to calculate it would be by realising that Jack only distributed 48 chocolates. We can find how many times 3 fits into 48 by dividing 48÷3=16.

Using algebra, we substitute the value we want to find with x. Here what we want to find is the number of friends that were at Jack's party.

We know that he started with 50 chocolates, then distributed 3× the number of friends present (which is x).
We write that down as 50−3x
(It's minus because when chocolates are distributed, Jack is taking away from what he has.)

We know that after this, there were only 2 chocolates left, so it's
50−3x=2

Then we proceed by moving all the numbers to the right until only x is left:

−3x=2−50
−3x=−48

x=−48−3

x=16

Conclusion: The number of people that attended the party was 16

What value of x is in the solution set of 3(x – 4) ≥ 5x 2?

Andrej [43]

Hope there are

3(x-4) >= 5x^2 or this 2 from the end what mean ?

3x-12 >=5x^2

0>=5xˇ2 -3x +12

5x^2 -3x +12 =0
