Answer:
52
Step-by-step explanation:
14+13= 27+2=29+23=52
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.
Suggestion: tell me that you want answer of all or anyone.
7,15,19,34 are not multiples of four. to find this answer out just divide four into them.
