Answer:
The Pearson product-moment correlation coefficient is
Step-by-step explanation:
The Pearson product-moment correlation coefficient (PMCC) is a numerical value between -1 and 1 that expresses the strength of the linear relationship between two variables.When r is closer to 1 it indicates a strong positive relationship. A value of 0 indicates that there is no relationship. Values close to -1 signal a strong negative relationship between the two variables.
To find the PMCC of the following data, you must:
Step 1: Find ,
and
as it was done in the table below.
Step 2: Find the sum of every column to get
Step 3: Use the following formula to find the PMCC.
Answer:
The lengths of three sides are <u>6 m, 6 m and 9 m</u>.
Step-by-step explanation:
Given:
Two sides of a triangle have the same length.
The third side measures 3 m less than twice that length.
The perimeter of the triangle is 21 m.
Now, to find the lengths of all three sides.
So, naming the three sides of triangle a, b, and c.
As given two sides of a triangle have the same length.
So, let the first side of triangle(a) be
And the other side(b) be same
Now, the third side(c) be
Perimeter = 21 m.
Now, putting formula to get the sides:
<em>Adding both sides by 3 we get:</em>
Dividing both sides by 4 we get:
Now, getting the sides of triangle by putting the value of :
a = 6 m.
b = 6 m.
c =
Therefore, the lengths of three sides are 6 m, 6 m and 9 m.
