Question

QUESTION 1 What is the mean of 21, 23, 35, 40)? o A. 27 B. 31.75 e C. 19 D.29.75

Answer 1

Answer:

D. 29.75

Step-by-step explanation:

To determine the mean, you must add up all the numbers and then divide that number by how many numbers you added.

Here,

21 + 23 + 35 + 40

= 119

You added 4 numbers (21, 23, 35, 40),

so, 119 / 4

= 29.75
