Answer:
Randomization removes lurking variables and biases.
Step-by-step explanation:
In case of an experimental design the groups are divided randomly.
Randomization is important so that there are no bias present in the study and to control any lurking variables. The controlling of the lurking variables provides an accurate result.
Lurking variables have a significant effect on the response variable. Presence of lurking variables can indicate a strong relation between variables or conceal any true relation between the variables.
Randomization thus gets rid of lurking variables and biases.
Also if randomization is used then each of the groups are similar in every way other than the fact that each group is provided with different treatment.

Hi! The correct answer is A. 80 Miles!
Step-by-step explanation:
Answer:
the line through the points negative 6 comma 0 and 0 comma negative 2
Step-by-step explanation:
Rewrite the equation to something you are familiar with such as the slope intercept form; y = mx + b. This means you need to solve for y.
3x + 9y = -18 --- divide everything by 3.
x + 3y = -6
3y = -6 - x
y = -2 - 1/3x
your slope is -1/3 and your y intercept is - 2.
remember, y-intercept is when x = 0. therefore, when x = 0, y = -2.
write as an ordered pair (0, -2). the only option that has (0, -2) is the second one.
Therefore, the line through the points negative 6 comma 0 and 0 comma negative 2.
10 because 8 squares plus 6 squared equals 100 and the root of 100 is ten
