Hello there! The answer to question 1:
A. 520,563
The answer to question 2:
D. 95
To solve question one, we need to find the average of these three numbers. To do so, we add all three first:
479,459 + 715,230 + 367,000 = 1,561,689
Then, after adding, we can divide our result by three because that is how many numbers were used.
1,561,689 divided by 3 = 520,563
Therefore, the average population of Ohio’s three largest cities is 520,563.
To find the answer to question two, we can start by adding the three numbers we have:
84 + 93 + 88 = 265
Because Horace had two tests where he scored in the eighties, we know that in order to average at least a 90, Horace will need to score either a 92 or a 95. When calculating, we will find that if Horace scores a 92, he will be at an average of 89.25. That means that our only reasonable answer is 95 because we can calculate that:
84 + 93 + 88 + 95 = 360
360 divided by 4 equals 90.
Therefore, scoring a 95 on Horace’s final test will put him right on the dot for an average of 90.
Your final answer is D, or 95. Horace will need to score a 95 on his final test to average out to a 90. If you need any extra help, let me know and I will gladly assist you.
