Percentage of students with GPA between 1.5 and 3.5 is 75% and Percentage of students that don't belong to freshmen is 73.9%.

<h3>How to Calculate the Percentage?</h3>

1) Total number of households with computer = 111,804

Percentage of Cincinnati households with computer =  82.1%

Thus;

Number of Cincinnati households with computer = 82.1% * 111804 ≈ 91791

2) Total number of students = 854

Percentage of students with GPA between 1.5 and 3.5 = 100 - (11 + 14) = 75%

3)  Total number of students = 854

Number of freshmen = 223

Thus;

Percentage of students that don't belong to freshmen = 1 - (223/854) = 1 - 0.2611 = 0.7389 ≈ 73.9%

4) We are given;

17% of the 198 seniors are on Academic Watch

10% of 223 freshmen are on Academic watch

Thus;

a) seniors on academic watch = 17% * 198 ≈ 34

b) freshmen on academic watch = 10% * 223 ≈ 22

c) Number of more seniors that freshmen on academic watch = 34 - 22 = 12

Which expression makes the equation true?
N76 [4]
1. C. 

The rule of powers is that when a parenthesis is raised to a power, you multiply the two numbers. Since it is being raised to the second power, it needs to have a 10 in the parenthesis. That would make 20. 

2. B

Firstly 10^2 = 100, so we know that the number must be 10. That leaves us with just A and B. Then we know the same thing from the previous equation, that they need to be multiplied together.
