Answer: A Yes, because the balls are randomly selected, the distances of the new ball can be compared to the distances of the original ball.
B Yes, because the original ball type is included in this experiment, the distances the different balls travel can be accurately compared.
Step-by-step explanation:
C No, because a placebo ball was not used, a comparison cannot be made to determine if the new ball travels significantly farther.
D No, because all of the new type of balls are not hit first, the distances they travel cannot be compared to the distances of the original ball.

The length of rectangular pool is 6 ft and width of rectangular pool is 2 ft.
Step-by-step explanation:
Given,
Area of rectangular pool = 12 square feet
Let,
Width of pool = w
Length of pool = l = 2w+2
Area = Length * Width
Dividing each term by 2;
Either,
w+3 = 0 => w=-3
Or,
w-2=0 =>w=2
As width cannot be negative, therefore,
Width of rectangular pool = 2 ft
Length of rectangular pool = 2w+2 = 2(2)+2 = 4+2 = 6 ft
The length of rectangular pool is 6 ft and width of rectangular pool is 2 ft.

The numbers are "x" and "y",
we suggest this system of equations.
x+y=24
x-y=15
solve by reduction method.
x+y=24
x-y=15
-----------------
2x=39 ⇒x=39/2=19.5
x+y=24
-(x-y=15)
-------------------
2y=9 ⇒y=9/2=4.5
The numbers are 19.5 and 4.5
To check
19.5+4.5=24
19.5-4.5=15
