Answer:

x = 39.1

Step-by-step explanation:

Points to remember

Mean of a data set is given by

Mean = (sum of data set)/Total number of data

To find the value of x

It is given a data set

31.7, 42.8, 26.4, x

Mean = 35

Sum of data set = 31.7 + 42.8 + 26.4 + x = 100.9 + x

(100.9 + x)/4 = 35

100.9 + x = 35 * 4 = 140

x = 140 - 100.9 = 39.1

Therefore x = 39.1
