For which data set is a linear regression most reasonable? A. A set of nine data pairs with a correlation coefficient r = –0.4 B. A set of five data pairs with a correlation coefficient r = 0.3 C. A set of four data pairs with a correlation coefficient r = –0.8 D. A set of six data pairs with a correlation coefficient r = 0.6
Answer:
Set of four data pairs with correlation coefficient r= -0.8 reasonable linear regression data set.
Step-by-step explanation:
Linear regression is a primary type of predictive analysis. It describes does a variable does a useful job. Which variable is significant.
Set of nine data pairs with correlation coefficient r = -0.4
Set of five data pairs with correlation coefficient r= 0.3
Set of four data pairs with correlation coefficient r= -0.8
Setoff six data pairs with correlation coefficient r = 0.6
A setoff four data pair with correlation coefficient r = -0.8 is the valid data set.
Because
r = -0.8
r2 = 0.64,
This is very close to 1 as compared to any other data pair.
Hence, Set of four data pairs with correlation coefficient r= -0.8 reasonable linear regression data set.
Answer:
C "a set of four data pairs with a correlation coefficient r = –0.8"

Solve y/-4 + 5 = 15. 80 -80 40 -40
Answer:
y = -40
Step-by-step explanation:
y/-4 + 5 = 15
y/-4 = 10
y = -40
Hey there!☺
[tex]Answer:\boxed{y=-40}[/tex]
[tex]Explanation:[/tex]
[tex]\frac{y}{-4}+5=15[/tex]
In our first step, we will simplify both sides of the equation:
[tex]\frac{x-1}{4}y+5=15[/tex]
Now we will subtract 5 from both sides:
[tex]\frac{-1}{4}y+5-5=15-5\\\frac{-1}{4}y=10[/tex]
Now in our last step, we will multiply both sides by 4/(-1):
[tex](\frac{4}{-1})\times(\frac{-1}{4}y)=(\frac{4}{-1})*(10)\\ y=-40[/tex]
y=-40 is your answer.
Hope this helps!☺

C 0.0450
d 0.0500
ed a Hint
Answer:
0.0520
Step-by-step explanation:
In this expression, we conclude that 1 is the least significant figures after decimal in this problem. The answer will be 0.0520.
What is Significant figures?Significant figures is the figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the multiplication and division is that the least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The rule apply for the addition and subtraction is that the least precise number present after the decimal point determines the number of significant figures in the answer.
The given expression is: 0.0702 - 1.35
0.0702 - 1.35
= 0.0520
In this expression, we conclude that 1 is the least significant figures after decimal in this problem.
The answer will be 0.0520.

A marathon runner ran 15 miles in 120 minutes. What is the ratio of minutes per mile?
Answer:
Step-by-step explanation:
Answer: So that means it would take him 7.9 minutes to run a mile
Step-by-step explanation:
Divide your run distance by your run time.
If you ran 2.5 miles and you ran for 20 minutes: 2.5 mi ÷ 20 min = 0.125 miles per minute. So the answer would be
15 miles= 79200
79200 divided by 120=660

2/3
units from B
Given :
A point x whose distance from A is 5 1/3 units.
distance between x and B is 2/3 units.
To Find :
Distance between A and B if they both are on left side of straight line from x.
Solution :
Let distance between A and B is d :
[tex]d=|A-B|\\\\d=|5\dfrac{1}{3}-\dfrac{2}{3}|\\\\d=|\dfrac{16}{3}-\dfrac{2}{3}|\\\\d=\dfrac{14}{3}\\\\d=4\dfrac{2}{3}\ units[/tex]
Therefore, distance between A and B is 4 2/3 units.
Hence, this is the required solution.
PLEASE HURRY which of the following points on the number line below best approximates the value of negative square root of 7.
Answer:
C
Step-by-step explanation:
The value of negative square root of 7 can be determined by either using a calculator or even just solely thinking about it. If we think about, negative square root of 4 is -2 and negative square root of 9 is -3. Therefore, the answer is C. We can also use a calculator to confirm the answer. -√7 is approximately -2.65 and therefore is a value between -2 and -3 which is point C.
The point C (-2.4) best approximates the value of negative square root of 7 on the given number line.
What is Number system?A number system is defined as a system of writing to express numbers.
The square root of 7 is approximately 2.65, so the negative square root of 7 is approximately -2.65.
Among the given points on the number line, the point that is closest to -2.65 is point C, which is at -2.4.
Therefore, point C (-2.4) best approximates the value of negative square root of 7 on the given number line.
