Respuesta :

Using the mean concept, it is found that you need at least 40 active minutes on Sunday to achieve your goal.

What is the mean?

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

In a week, there will be 7 observations, and a bar graph can represent each observation(time in minutes). They are given as follows:

15, 45, 20, 0, 60, 30 and x.

We want the mean to be of 30, hence:

30 = (15 + 45 + 20 + 0 + 60 + 30 + x)/7

170 + x = 210

x = 210 - 170

x = 40.

You need at least 40 active minutes on Sunday to achieve your goal.
