Find the value of x such that the data set 31.7, 42.8, 26.4, x has a mean of 35

Solution:

Given,

Mean = 35.

To find the mean of a data set, we need to add all the values together and divide by the number of values in the set.

The sum of the values in the given data,

31.7 + 42.8 + 26.4 + x

= 100.9 + x.

Mean of the data [100.9 + x]/4 = 35.

100.9 + x = 140

x = 140 - 100.9

x = 39.1

Therefore, the value of x is 39.1

Find the value of x such that the data set 31.7, 42.8, 26.4, x has a mean of 35

Summary:

The value of x when the data set is 31.7, 42.8, 26.4, x has a mean of 35 is 39.1
