The percent of variation is 85.1%. If you enter the numbers into a calculator and store the regression equation, it will be the r^2 value when calculated.
hi I like ur question! like a lot!
X is the amount of months
y is the total bill
75x +30 = y
This is because 30 dollars is a one time fee so you will only add it once. 75 dollars is a recurring fee, so you pay it every month. Y is the total cost for cable.
Are there answer options??
