Answer:
The total number of U.S. high school students that played on a sports team that year can be estimated to be 7,950,000.
Step-by-step explanation:
From the random sample, we can expect that 
of all students played on a sports team that year. So in the bigger sample of 15900000 high school students, we can expect 
students to have played on a sports team that year.
Step-by-step explanation:
By cross multiplication,
→ 83(5) = 4x(7)
→ 415 = 28x
<h3>→ 415/28 = x</h3>
2(4z - 6 - 6) = 170 - 46
2(4z - 12) = 124 |use distributive property: a(b - c) = ab - ac
8z - 24 = 124 |add 24 to both sides
8z = 148 |divide both sides by 8
z = 18.5
