a. multiple regression model
b. a least squares regression model
c. quadratic regression model
d. a simple regression model

Option C) Quadratic regression model

Step-by-step explanation:

Quadratic regression model

where x is the independent variable and is the dependent variable.

Thus, the correct answer is

Option C) Quadratic regression model

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.

the answer will be b x² +x-1
