a. Use the linear regression equation from Part C to calculate the predicted adult
weight for each birth weight. Round to the nearest hundredth. Enter these in the third
column of the table. (2.5 points)
b. Find the residual for each birth weight. Round to the nearest hundredth. Enter these
in the fourth column of the table. (2.5 points)
c. Plot the residuals. (3 points)

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
