Question

what is the mean? if the answer is a decimal, round it to the nearest tenth. 50 57 40 44 42

Explanation:

Step1: Sum the numbers

We have the numbers 50, 57, 40, 44, and 42. First, we find their sum.
\(50 + 57 + 40 + 44 + 42\)
\(= 107 + 40 + 44 + 42\)
\(= 147 + 44 + 42\)
\(= 191 + 42\)
\(= 233\)

Step2: Divide by the number of terms

There are 5 numbers. So we divide the sum by 5 to find the mean.
\(\text{Mean} = \frac{233}{5}\)
\(= 46.6\)

Answer:

46.6
