Yes, you are correct. Suppose the relationship is p=aq. Put p=10 and q=2 in, we can get p=5q. So when q=20, p=20*5=100. So the answer is D. Be confident with yourself~
Answer: A, B, and C are positive constants and that x+y= C. Show that the minimum value of +Ax%5E2%2BBy%5E2+ occurs when .
Step-by-step explanation:
;)
Find the mean of the first four test scores first.
(Add all numbers in set and divide by how many numbers there are)
81 + 87 + 71 + 89 = 328 / 4 = 82
Then, find the mean with the 85 added as the fifth term.
81 + 87 + 71 + 89 + 85 = 413 / 5 = 82.6
The impact that the 85 had on the mean test score was that the mean/average increased by 0.6.
