Hello from MrBillDoesMath!
Answer:
x = 12
Discussion:
From the diagram, the two triangles appear to be similiar. Then
28/7 = (6x + 28) /25
as the ratio of corresponding parts of similar triangle are the same.
28/7 = (6x +28)/25 => simplify. 28/7 = 4
4 = (6x + 28)/25 => multiply both sides by 25
4*25 = 6x + 28 => simplify, 4 * 25 = 100
100 = 6x + 28 => subtract 28 from both sides
100 -28 = 6x => simplify. 100 - 28 - 72
72 = 6x => divide both sides by 6
72/6 = 12 = x
Thank you,

Piece(1)=36+9= 45 in
45 in > 44 in
so, piece(1)>piece(2)
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.
