(2j+7)(2j−7)
=(2j+7)(2j+−7)
=(2j)(2j)+(2j)(−7)+(7)(2j)+(7)(−7)
=4j2−14j+14j−49
=4j2−49
The probability of the black sock is 6/26 for the white is 16/26 and for the brown is 4/26
Answer:
The equation of the regression line is:

Step-by-step explanation:
The Least Squares Regression Line is the line that makes the vertical distance from the data points to the regression line as small as possible. It’s called a “least squares” because the best line of fit is one that minimizes the variance.
We have the following data:

To find the line of best fit for the points:
Step 1: Find
and
as it was done in the table
Step 2: Find the sum of every column:

Step 3: Use the following equations to find a and b:

Step 4: Assemble the equation of a line

The graph of the regression line is:
You put .875 over the number 1 to make it a fraction so
Answer:
Step-by-step explanation:
You first times the width by the height than divide by 2
