This is about knowledge between Correlation and Regression.
Option A and E are correct.
Option A; Under different types of correlation coefficient they tend to make use of different range for their definitions but it is always between minimum of -1 and maximum of 1. Thus, the statement is correct.
Option B; It must not be positive because as stated in option A above negative values can be used.
Option C; No, it doesn't indicate percentage of points because in the definition i gave earlier, there is nothing like that. Besides, this is in regression and not correlation.
Option D; This is incorrect as the definition doesn't support it.
Option E; This is correct because positive correlation means that the two variables increase at the same time or decrease at the same time. Thus, it means the regression line will be positive as long as correlation is positive.

Answer:
What he said ⬆️
Step-by-step explanation:
Ta-Da
Answer:
He worked 8 hours overtime.
Step-by-step explanation:
A man was paid per hour up to 40 hours = $3.00
He was paid for 40 hours = 40 × 3 = $120
He did overtime, for which he was paid twice of the regular payment = 2(3)
= $6.00
He was paid for his overtime = 168 - 120 = $48.00
His overtime payment per hour = $6.00
He did overtime = 48 ÷ 6 = 8 hours
He worked 8 hours overtime.
Step-by-step explanation:
4x -2 = -18
to solve for x
4x = -16
x = -4
Answer:x=5
Step-by-step explanation:
First we do the parenthesis
-4(7+2x)=-7x-33
To get
-28+-8x=7x+-33
and
-8x-28=-7x-33
Then we Add 7x to both sides.
-8x-28+7x=-7-33+7x
-x-28=-33
Then we Add 28 to both sides.
-x-28+28=-33+28
-x=-5
Lastly Divide both sides by -1.
-x/-1=-5/-1
X=5
Answer:
see below
Step-by-step explanation:
You solve an equation by undoing what is done to the variable. When the variable is squared, as here, you undo the squaring by taking the square root. Any operation you do on one side of the equation must also be done on the other side. Hence, you take the square root of both sides of the equation.
