Answer:
provides information about the strength of a relationship
Step-by-step explanation:
A numerical measure of strength in the linear relationship between any two variables is called the Pearson's product moment correlation coefficient.
The co efficient of correlation is a pure number denoted by r , independent of the units in which the variables are measured that can range from+1 to -1 .
The sign of r indicates the direction of the cor relation.
When r= 0 it does not mean that there is no relationship . For example if the observed values lie exactly on a circle , there is a relationship between variables but r = 0 as r only measure linear cor relation.
The 2nd statement given is the correct answer.
It is not related to ordinal or nominal properties and it does show direction.
The midpoint is just the average of the coordinates of the endpoints.
((-8+2)/2, (-3-5)/2)
(-6/2, -8/2)
(-3,-4)
The statement that line segments that have the same length are called similar segments is false
<h3>How to determine the true statement?</h3>
The statement is given as:
Line segments that have the same length are called similar segments.
As a general rule:
Line segments that have the same length are similar segments.
However, line segments that have the same length are not called similar segments
Instead, line segments that have the same length are called congruent lines
This means that the the statement that line segments that have the same length are called similar segments is false
Hence, the statement that line segments that have the same length are called similar segments is false

Answer:
Discounted amount = $10
Sales price = $40
Step-by-step explanation:
Given:
Phone cost = $50
Discount rate = 20%
Find:
Discounted amount and sales price
Computation:
Discounted amount = Phone cost x Discount rate
Discounted amount = 50 x 20%
Discounted amount = $10
Sales price = Phone cost - Discounted amount
Sales price = $50 - $10
Sales price = $40
Answer:
y=-5
