Question

A group of five students have a mean test score of "34.2." Another student has a score of 50. What is the mean average of all "six" students?

Answer 1

Answer:

The mean average of all "six" students is 36.83.

Step-by-step explanation:

Mean:

The mean is the sum of all scores divided by the number of scores.

A group of five students have a mean test score of "34.2." Another student has a score of 50.

This means that the sum is given by:

$S = 5*34.2 + 50 = 171 + 50 = 221$

What is the mean average of all "six" students?

Sum of 6 students is 221. So

$M = \frac{221}{6} = 36.83$

The mean average of all "six" students is 36.83.
