Ruth, Daisy, and Martin share £750 in the ratio of 3:5:7. Determine how much money Ruth receives.

Answers

Answer:

Ruth receives £150

Step-by-step explanation:

sum the parts of the ratio, 3 + 5 + 7 = 15 parts

divide the total £750 by 15 to find the value of one part of the ratio

£750 ÷ 15 = £50 ← value of 1 part of the ratio

Then

3 parts = 3 × £50 = £150 ← amount Ruth receives

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 $-1 \le r \le 1$ 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.
