The amount of variance for y that is predicted by its relationship with x is 64%.
<h3>
How much variance is predicted?</h3>
Variance measures the rate of dispersion of a data point around the dataset. It can be calculated by finding the square of the standard deviation of a dataset. Variance measures the variation of a data set.
Correlation is a statistical measure used to measure the linear relationship that exists between two variables. The greater the correlation coefficient is closer to one, the greater the linear relationship that exists between the two variables. A positive correlation occurs when the two variables move in the same direction.
Variance = (correlation coefficient²) x 100
(0.80²) x 100
0.64 x 100 = 64%

Answer:
16
Step-by-step explanation:
First. for you to find the radius of the circle you must know the steps/formula to find the area.
the radius of the circle times pie 3.14.
so x times 3.14 will give you 50.24
the opposite of multiplication is division
so 50.24 divided by 3.14 is 16
because 16 times 3.14 is 50.24 sq in.
Answer:
The matrix that represents the system of equations is:
Step-by-step explanation:
We will use the first column for x, the second to y and the last for the independent term.
We have:
Then, we can write the matrix to represent the system of equations as:
Answer:
A = a^2.....the Area (A) of a square = a^2...where a = one side
79 = a^2...now take the sqrt of both sides, this eliminates the ^2
sqrt 79 = a
8.888 rounded = 8.89 = a......so one side = 8.89 ft
Step-by-step explanation:
