PLZ HELP ME ITS DUE TODAY What is the quadratic regression equation for the data set?

yˆ=−0.175x2−3.786x+121.119

​yˆ=−0.175x2+3.786x−121.119​

​yˆ=−0.175x2+3.786x+121.119​

​ ​ ​yˆ=−0.175x2−3.786x−121.119​ ​ ​
x y
6 100
3 110
10 50
3 90
5 120
15 30
9 70

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
