Data on first test: 50, 50, 50, 50, 50
Mean = 250 / 5 = 50
In the next test, Data is: 50, 50, 50, 50, 100
Mean = sum of data / number of data
Mean = 50 + 50 + 50 + 50 + 100 / 5
M = 300 / 5
M = 60
In short, Your Answer would be 60
If You're looking for combined progress (average of class then, it would be: 50 + 60 /2 = 110/2 = 55
Hope this helps!

Answer:
The width is 10 inches.
x(x + 3) = 70
x² + 3x = 70
Subtract 70 from both sides.
x² + 3x - 70 = 0
Factor the trinomial
(x - 7)(x + 10) = 0
Set each equal to zero.
x = - 7, - 10
Distance can't be negative so x = 7 is the right one. Now we plug in for the length (x + 3)
x + 3
7 + 3
10
