Answer 2

Guya's mean practice time per day during the given week = 35.7 mins

Step-by-step explanation:

Look at the attached picture:

The plot tells us that Guya practiced 10 minutes on Sunday, 30 minutes on Monday, 20 minutes on Tuesday and so on

So, in the whole week she practice minutes.

10+30+20+40+50+40+60 = 250 minutes

The mean of a set of numbers is defined as the sum of the numbers divided by the number of given terms. So, we have seven numbers adding up to 250, and the mean is thus

250/7 = 35.714285

By rounding off we get:

35.7

Guya's mean practice time per day during the given week = 35.7 mins
