Accepted Solution

A:

The plot tells us that Guya practiced 10 minutes on Sunday, 30 minutes on Monday, etc.So, in the whole week she practiced[tex] 10+30+20+40+50+40+60 = 250 [/tex] minutes. The mean of a set of numbers is defined as the sum of the numbers divided by the cardinality of the set. So, we have seven numbers adding up to 250, and the mean is thus[tex] \dfrac{250}{7} = 35.\overline{714285} \approx 35.7 [/tex]
