it would be something like this:
f(x) = 12 + x(4%)
but if you want it in y format then:
y = 12 + x(4%)
Answer:
13/3
Step-by-step explanation:
ON=LM
8X-8 = 7X+4
let's find "x"
8x - 7x = 4 + 8
x = 12
now NM = OL
X-5 = 3Y-6
then
(12) - 5 = 3y - 6
7 = 3y - 6
3y = 7+6
y = 13/3
Finding the difference is the same as subtracting the smaller from the larger
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!
