Step-by-step explanation:
5% increase is 105% or 1.05
12000×(1.05)¹²
= 21,550.275912
The mean of the scores to the nearest 10th digit will be 74.9.
<h3>What is Mean?</h3>
The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean.
Then the mean is given as,
Mean = (Total score) / (total student)
The total score will be
Total score = 65 x 8 + 70 x 7 + 75 x 3 + 80 x 8 + 85 x 3 + 90 x 2 + 95 x 2
Total score = 520 + 490 + 225 + 640 + 225 + 180 + 190
Total score = 2470
The total number of students will be
Total student = 8 + 7 + 3 + 8 + 3 + 2 + 2
Total student = 33
Then the mean will be
Mean = 2470 / 33
Mean = 74.85 ≈ 74.9
