805 because 3220 divided 4 equals that
It's just one, if there isn't any other number attached to the x^2 you can just assume the leading coefficient is 1
She eats 180 kg of popcorn every month.
Step-by-step explanation:
Since Ms. Louis' daughter eats 9 bags a month and every bag weighs 20 kg you will just need to multiply the number of bags (9) × the weight of the bags (20) to figure out how many kilograms she eats. In this case she eats 180 kilograms of popcorn a month.
Answer: 31%
Step-by-step explanation:
Formula : Percent of the variability = 
, where
= Coefficient of Determination.
SSR = sum of squares of regression
SST = total sum of squares
is the proportion of the variation of Y that can be attributed to the variation of x.
As per given , we have
SSR = 14.55
SST= 46.8
Then, the percent of the variability in y that can be explained by variability in the regression model =
Hence, the percent of the variability in y that can be explained by variability in the regression model = 31%
180 x 0.06 = 10.80; $10.80.
