Which Inequality Is Represented By The Number Line Diagram Shown Below

Answers

Answer 1

I think it’s the second one, I did the test and got an A

x < 0

(Sorry I responded late hope this helped)

Answer 2

Answer:

x>-1

Step-by-step explanation:

Because the sign is going to the right so it is automatically less than, and the point is on -1 going to the right. I took the test don't worry this answer is right. :)

The table shows the test scores and the sleep averages of several students.

a. Write the least squares regression equation that models the data. Let x = hours of sleep and y = test score.

b. Use the equation to determine the approximate test score of a student who sleeps an average of 8 h a night. Show your work.

Answers

hey someone else has already answered this!

a. To find the least squares regression equation for a group of (x,y) points:

Step 1: For each point(x,y), we need to calculate x² and xy first.

Step 2: Sum all x, y, x² and xy, which gives us Σx, Σy, Σx² and Σxy

Step 3: Calculate Slope m: m = (NΣxy − Σx Σy)/ N(Σx²) − (Σx)² , here N is the number of data.

Step 4: Calculate Intercept b: b = Σy − m(Σx)/ N

Step 5: Assemble the equation as y= mx+b

Here, we have ∑x = 120, ∑y= 1379, ∑x²= 919.5, ∑xy= 10466 and N= 16

So, m= (NΣxy − Σx Σy)/ N(Σx²) − (Σx)²

=

=

=  

= 6.33

and b = Σy − m(Σx)/ N

=

=

=

= 38.71

So, the least squares regression equation is : y= mx+b ⇒ y= 6.33x +38.71

b. When x= 8, then y= (6.33×8)+38.71 = 50.64 + 38.71 =89.35

The approximate test score of a student who sleeps an average of 8 h a night is 89.35%

EVERYTHING IS FROM sicista on brainly!

Answer:

A way to write the least regression equation that models is data y = mx + b => y= 6.33x + 38.71 and as for problem B when X = 8 then y = (6.33 x 8) + 38.71 = 50.64 = 38.71 = 89.35 so the estimated test score of a student who sleeps eight hours a night is equal to 89.39%

The floor of a rectangular living room is 12 feet by 16 feet. What is the distance between
opposite corners of the living room?

Answers

Answer:

The width of Dana's living room is 16 feet.

Explanation:

Because Dana's living room is rectangular and we are given the length of one side and the length of the diagonal we can use the Pythagorean Theorem to solve this problem.

For a right triangle which the length, width and diagonal make up the Pythagorean Theorem states:

Let the length of 12 be

Answer:

6, -8

Step-by-step explanation:

You need to find out the possible values of which X cannot equal

In fractions the only way that's possible is if the denominator= 0

Because everything in the denominator is being mulitplied this is pretty simple

We need either parantheses to equal 0

so we take them and solve for 0

we have

x-6= 0

x=6

x+8=0

x= -8
