A class tracked the number of hours each student plays video games in a week. Answer the questions below.

Based on the data in the line plot, calculate and show work for questions a-e.

a) Find the mean. (3 points)

b) Find the median (3 points)

c) Find the mode. (2 points)

d) Find the range. (2 points)

e) What percentage of the students play video games for more than 4 hours (round to the nearest tenth)? (4 points)

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

32

step-by-step explanation:

it is 10.6 according to my calculations
