<h3>HOW TO CALCULATE TOTAL FROM MEAN?</h3>
The mean of a set of data can be calculated by dividing the total sum by the number of data given.
According to this question, Sara is said to have a mean score of 62 in 5 tests and another mean score of 68 in 6 tests.
- First total score = 62 × 5 = 310
- Second total score = 68 × 6 = 408
Therefore, Sara's score in the sixth test can be calculated by subtracting 310 from 408 to give 98.

B. getting tails on a coin toss : NO, I's a simple event
C. drawing an ace from a deck of cards : NO, I's a simple event

Since perimeter means adding all 4 sides, you divide 86 divided by 4 equals = 21.5. Then do 21.5 + 21.5 which equals 43. And 43 + 43 = 86. So two sides are 21.5, and the other two sides are 43. So 21.5 < 43. 21.5 is the shortest sides. Hope this Helps!
