inna [77]

Answer:

5/24 or 20.8%

Step-by-step explanation:

 

Probability that the 7th grader is a boy = number of boys/(total kids) = 4/(4+4) = 1/2

 

Probability that the 8th grader is a boy = 5/(5+7) = 5/12

 

Probability that both are boys = 1/2*(5/12) = 5/24 or 20.8%

A soccer team won only 10 of their first 30 games. How many of their remaining 20 games will they have to win to have a .500 rec
jeka94

Answer: 5 games

Step-by-step explanation: A .500 record means that the soccer team won half of their games ( that's how I interpret it). Since they are going to play 30 games, they need to win half of 30 or 15 games to have that record. 15-10 = 5. So, they need to win 5 more games to have a .500 record.

Four times the number of coins in my pocket plus five more is twenty-nine. Write an equation for the number of coins in my pocke
Lynna [10]
There are six coins already in pocket, but let’s say we don’t know it.

We would figure it out by reversing the problem. Let’s start with twenty-nine. We would subtract 5, because we are reversing. Now we have 24. Now, let’s divide by four. We would get 6.

A simpler answer would be 29 - 5 [divided by] 4 = [answer]
