Solution :
1). The cost of the formula is given as :
$ 19,350 + $12 x
2). 95% 
for the prediction is :
(rounding off)
3). r = 0.92
Therefore, 
That is 84.64 % of the variability in the moving cost is best explained by the number of moves.
In order to determine which subset it belongs, we must rewrite
as
All these three numbers are irrational numbers, hence their product is also irrational

Answer:
x=28
Step-by-step explanation:
We can use similar triangles and proportions to solve this problem. Put the side of the small triangle over the same side of the larger triangle.
x 42
---------- = ----------
x+10 42+15
Simplify
x 42
---------- = ----------
x+10 57
Using cross products
57x = 42 (x+10)
Distribute
57x = 42x+420
Subtract 42x from each side
57x-42x = 42x-42x +420
15x = 420
Divide each side by 15
15x/15 = 420/15
x=28
900 because 9 is greater than 5 so it rounds to my answer.
A + s = 456........a = 456 - s
3.5a + s = 1131
3.5(456 - s) + s = 1131
1596 - 3.5s + s = 1131
-3.5s + s = 1131 - 1596
-2.5s = - 465
s = -465/-2.5
s = 186 <====== student tickets sold
a + s = 456
a + 186 = 456
a = 456 - 186
a = 270 <==== adult tickets sold
