To find the range of these scores, we must take the largest scores and subtract the smallest from it.
The largest score is 99, and the smallest score is 80.
99 - 80 = 19
I think the answer is C.
First start by factoring, you should get (2n-3)(n-2)=0
Then start to solve for n.
2n-3=0
n-2=0
n=2, n= 3/2
I hope that helps.
I guess the mean is always
this question is not clear.
No, because they're in the same place value.
X = 59, y = 44
2x + 18 + x - 15 = 180
3x + 3 = 180
3x = 177
x = 59
x - 15 = y
59 - 15 = y
44 = y
