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

Let the length of 12 be

and because the diagonal is the hypotenuse of the triangle (the side opposite the right angle) we let

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.
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%
