Use graphing technology (TI calculator or Desmos) to find the linear regression equation that models the data. Let x equal the hours of sleep and y equal test score. Explain the steps you use. Use the equation to determine the approximate test score of a student who sleeps an average of 7.5 hours a night. Show your work.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

are ya tryin to ask something or is this a statement

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
