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.
Answer:
A
Step-by-step explanation:
10x3=30
15x2=30+10=40
15x3=45 movies for less
To find the area of each backyard, we need to multiply the length and width together.
For Branda, her yard is 35 by 90, which means the area is 35*90 which = 3150.
For Laurie, her yard is 40 by 65, which means the area is 40*65 which = 2600.
Now, we are asked to find the difference between Branda and Lauries yard areas. The difference means how much larger Branda's area is than Lauries.
This means we have to subtract Laurie's area from Branda's.
So, we do 3150 - 2600 = 550
So, our answer is 550ft^2
