Answer:
Sampling variation
Step-by-step explanation: took the quiz
2 hours = 120 minutes
120/30 = 4
1/4 of 2 hours is 30 minutes.
Answer:
45.5
Step-by-step explanation:
First you would find 1/3 third of 10.50 and it is 3.5, you would then do 10.50 x 4 since it said 10.50 per half a yard, so you would do times 4 and you would get 42, you would then add 42 + 3.5 which equals 45.5.

There's no division by zero, so x can't be a value which x - 6 = 0
x - 6 ≠ 0
x ≠ 6
Hey there! Direct variation, a concept commonly applied to linear equations.
The constant of variation is a concept which simply refers to the change in y, based on the change in x. If this change is constant, then it is a constant of variation.
You can find the constant of variation (usually referred to as 'k') by dividing any point's y-value by its x-value.
In this instance, we have the point (3.5, 14)
14 / 3.5 = 4
The constant of variation for this equation would be 4.
