Answer:
There is no basis for comparison because the effect of the other variables that are not being studied are not minimized
Step-by-step explanation:
The rate at which each type of ball bounce are;
Tennis balls;
The height to which the ball is must rebounds ≈ 111 cm
The height from which the ball is dropped = 200 cm
Surface = Steel plate
Basketballs;
The height to which the ball must rebounds ≈ 5.35 inches
The height from which the ball is dropped = 72 inches
Surface = Wooden floor
Squash balls
The height to which the ball must rebounds ≈ 29.5 inches
The height from which the ball is dropped = 100 inches
Steel plate at 70°
Therefore, given that the experimental are performed with different variables of height from which each type of ball is dropped, the surface to which the ball is dropped, the angle of the surface to which the ball is dropped, there is no controlled variable to provide a basis for comparison

Answer:
C
Step-by-step explanation:
The function f(x) = -1/3x - 5 will be verbally described using the words for the operations of multiplication and subtraction. These words would include difference, product, decrease, subtracted, less than and times. The options include:
A. The function value is the difference between x times -1/3 and 5.
This is the equation since it separates the -1/3x and 5 terms using the word and.
B. The function value is 5 less than the product of x and 1/3.
This is the equation since it separates the -1/3x and 5 terms using the word and.
C. The function value is -1/3 of x subtracted from 5.
This is NOT the equation since it DOES NOT separate the -1/3x and 5 terms using the word and. It also suggests 5 - 1/3x by subtracting from 5.
D. The function value is -1/3 of x decreased by 5.
Though this doesn't use the word and, it separates the -1/3 and 5 terms by the order and still subtracts 5.
