Find the total points for each group:
31 students averaged 82, so the total points were 31 x 82 = 2542
2 students averaged 88, so the total points were 2 x 88 = 176
Now add the total points and divide by 33 students (31 +2):
2542 + 176 = 2718
2718 / 33 = 82.36
The average is 82.36 ( Round as needed).
Answer:
7 is median, 1 is minimum, 12 is maximum, 11 is upper quartile, 2 is lower quartile
<h3>
Answer: C) integers and rational numbers</h3>
Explanation:
The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} basically any number that does not have a decimal or fractional part to it. We can say that this set is composed of positive and negative whole numbers along with 0. So this is why -3 is in the set of integers.
The value -3 is not in the set of whole numbers because the set of whole numbers is {0, 1, 2, 3, 4, 5, 6, ...}, so this rules out choice D.
Choice B is also eliminated because -3 is a rational number. We can write -3 as a fraction of two integers, example: -3 = -3/1. Any rational number is not irrational, and vice versa.
Choice A is ruled out because it's not the most complete answer (though its technically true).
Answer:
8
Step-by-step explanation:
AB^2 = AD * AC
we got the answer
Your answer D. 8 is right; this is
64, which we know is 3 because 4^3 is 64.
