Answer: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%

Step-by-step explanation:

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%

L.) How do you construct congruent segments, segment bisectors, angles, and angle bisectors using tools such as a compass and a
kondor19780726 [428]

Answer:  

Construction of congruent segment: First we take the measurement of the line segment with help of marked scale or a compass, then by pointing the measurements we can get the congruent line segment.

Construction of congruent angle:

Step 1: Make two congruent segments,

Step 2: Adjust compass in a fixed length.

Step 3: Make an angle on any side of one segments with help of compass,

Step 4 : Again, make an angle on any side of the another segment with the same adjusted compass.

Construction of segment bisector,

Step 1: First place the compass on the one end of the segment,

Step 2: Adjust the compass approx to the half length of the segment,

Step 3: Draw arc above and below to the segment,

Step 4: Now, go the other end and by the same length draw two arcs by crossing the previous arcs.

Step 5: join the above and below crossed marks.

Construction of angle bisector:

Step 1: Place the compass on the vertex of the angle,

Step 2: Adjust the compass in any length,

Step 3: Make an arc in one segment of the angle and from that arc again Make an arc above the angle

Step 4: Make an arc of the same length in the another segment by the same vertex and crossed the arc made above the vertex.

Step 5: join the point of crossing and the vertex of the angle.
