Which value of a correlation coefficient represents the strongest relationship between the two variables in a given linear regression model? a) -0.94
b) 0
c) 0.5
d) 0.91
Answers
Answer: a) -0.94
Explanation:
The closer r gets to +1 or -1, the stronger the linear relationship will be.
If r is really close to +1, then we have a strong positive linear relationship. If r is close to -1, then we have a strong negative linear relationship.
Of the four choices given, we see that r = -0.94 is the closest to either endpoint mentioned. The next closest is r = 0.91
Put another way, we're looking for the r value that is furthest way from 0, but also that makes the inequality true. Choice A fits that description best.
Final answer:
The value of -0.94 represents the strongest relationship between the two variables in a given linear regression model.
Explanation:
The value of a correlation coefficient ranges from -1 to 1. The closer the value is to -1 or 1, the stronger the relationship between the two variables in a linear regression model. Therefore, the value of "-0.94" represents the strongest relationship among the given options. A negative correlation coefficient indicates an inverse relationship, meaning that as one variable increases, the other variable decreases.

Let x = solution with 32% sodium
y = solution with 12% sodium
Overall balance
x + y = 50
Component balance
.32x + .12y = 50(.20) =10
Solving simultaneously,
x = 20
y = 30

We take the information from the text given, to find the number of pieces.
We have that:
- One piece is 1/4 of the entire pie.
- The other n pieces are each 1/8 of the pie.
Doing this, we get that the number of pieces is 7 pieces, option D.
Sum:
The entire fraction pie is:
The entire fraction is 1, so:
How many pieces of pie are there?
We have to solve the equation for n, so:
6 pieces at 1/8, and the 7th at 1/4. Thus, there are 7 pieces, and the correct answer is given by option D.

Answer:
D
Step-by-step explanation:
1/4 of the pie is one piece. This leaves 3/4 of the pie. Each remaining piece is 1/2 of the larger quarter piece. The smaller pieces are 1/8 of the pie.
The fraction 3/4 = 6/8.
This makes 6 smaller pieces. each of 3 quarters is split in half.
6 + 1 = 7.
7 pieces in all.
If you do not like arithmetic, draw a picture. Split the pie in quarters. Cut all except for one of them in half. This gives 7 pieces.
