The scatter plot shows the number of minutes Guya practiced the flute each day in a given week What is Guyas mean practice time per day during the given week Ro class=

Respuesta :

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]

The mean practice time spent by Guya is 35.7 minutes

From the graph ; we can obtain the values of each point ;

  • 10 mins, 30 mins, 20 mins, 40 mins, 50 mins, 40 mins, 60 mins

The value of the mean can be obtained using the relation :

  • ΣX/ n
  • Where, n = frequency

The mean = (10 + 30 + 20 + 40 + 50 + 40 + 60) ÷ 7

The mean = 250 ÷ 7

The mean = 35.714 minutes

The mean practice time rounded to the nearest tenth is 35.7 minutes
