A=Adam
m= Melissa
a+m = 32
m= 3a
Then 3a + a = 32 or 4a =32 then a = 8
Answer:
(C) Whether or not a subject attends preschool
Step-by-step explanation:
In research studies, variables are used to explain differences in another variable. The explanatory variable (also known as independent or predictor variable) is used to explain differences in the response variable (dependent or outcome variable).
<em>It is important to know that the explanatory variable is the variable that is manipulated by the researcher. </em>
The facts that are not being manipulated are the income of the children studied, and what happens after attending or not preschool program. The variable the researcher is manipulating is the assignation to groups that will or will not attend preschool. Therefore the correct answer is:
(C) Whether or not a subject attends preschool

Rates Question
12 A highway had a landslide, where 3,000 cubic yards of material fell on the road, requiring 200 dump truck loads to clear. On another highway, a slide left 40,000 cubic yards on the road. How many dump truck loads would be needed to clear this slide?
3,000 yd3 = 200 dtl
40,000 yd3 × 200 dtl = 2,667 dtl
3, 000 yd3
Answer:
Results are below.
Step-by-step explanation:
<u>We will take into account the differential costs only. Therefore, the costs of sugar beets and to crush them are irrelevant to decision making.</u>
<u>Beet fiber:</u>
Sold as is= $25
Continue processing= 57 - 16= $41
It is more convenient to process further the beet fiber.
<u>Beet juice:</u>
Sold as is= $39
Continue processing= 84 - 22= $62
It is more convenient to process further the beet juice.
