Answer:

C.) each treatment is thought of as a value of the explanatory variable

Step-by-step explanation:

The main purpose for using randomization in an experiment is to control the lurking variable and establish a cause and effect relationship.

If we do not control lurking, or confounding, variables, we cannot accurately establish a cause and effect relationship; this means we cannot ensure that each treatment is a value of the explanatory variable.

Answer:

Point B

Step-by-step explanation:

Lines given:

y= 2/5x - 1/2
y= -1/3x +2/3

x coordinate of intersection of given lines is:

2/5x - 1/2= -1/3x+2/3
2/5x+1/3x= 2/3 +1/2
6/15x+5/15x= 4/6+3/6
11/15x=7/6
x= 7*15/11*6
x= 35/22

For this value of x, the value of y is:

y= 2/5*35/22 - 1/2
y=14/22- 1/2
y= 3/22

As per graph point (35/22, 3/22) is point B

In a basketball game Elena scored twice as many points as Tyler Tyler scores four points fewer than Noah and Noah scores three p

Full question:

In a basketball game, Elena scores twice as many points as Tyler. Tyler scores four points fewer than Noah, and Noah scores three times as many points as Mai. If Mai scores 5 points, how many points did Elena score? Explain your reasoning

Answer and explanation:

We start from known to unknown. We know that Mai scored 5 points and so we work from here.

Since Mai scored 5 points and Noah scored three times as many points then Noah's score = 3×5= 15 points

Since Tyler scored four points less than Noah, Noah's score= 15-4= 11 points

Finally Elena's score is twice that of Tyler hence Elena's score =2×11= 22 points
