Answer:
-15 < x
Step-by-step explanation:
Since all terms are a multiple of 4, it can be convenient to start by dividing the equation by 4.
-16 < 2 + x - 3
-15 < x . . . . . . add 1 to both sides, collect terms
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!
