QUESTION 1<br> What is the mean of 21, 23, 35, 40)?<br> o A. 27<br> B. 31.75<br> e C. 19<br> D.29.75
tangare [24]

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

Hope this helps and a thank won't hurt! :)
