The owner of a moving company typically has his most experienced manager predict the total number of labor hours that will be re

quired to complete an upcoming move. This approach has proved useful in the past, but the owner has the business objective of developing a more accurate method of predicting labor hours. In a preliminary effort to provide a more accurate method, the owner has decided to use the number of cubic feet moved and the number of pieces of large furniture as the independent variables and has collected data for 36 moves in which the origin and destination were within the borough of Manhattan in New York City and the travel time was an insignificant portion of the hours worked. If the sum of squares Y is 2,685.9 and the sum of squares error is 123.97.

Answer:

0.9538

Step-by-step explanation:

The computation of the proportion of variation in labor hours is explained by the number of cubic feet moved is shown below:

Here the R^2 coefficient of determination, would be determined and applied the same

R^2 = 1 - SSE ÷ SST

= 1 - 123.97 ÷ 2685.9

= 0.9538

Which of the following capital letters show an example of perpendicular line segments? A)L B)N C)V D)Z
nikdorinn [45]

The capital letter that shows an example of perpendicular line segments is: A. L (see attachment).

<h3>What are Perpendicular Line Segments?</h3>

Perpendicular line segments are lines or rays that intersect at a point to form right angles (angle 90 degrees) at their point of intersection.

When two lines intersect, and at their point of intersection, the angle formed is a right angle, then both lines are perpendicular line segments just like the lines that forms letter L as shown in the diagram attached below.

Therefore, the capital letter that shows an example of perpendicular line segments is: A. L (see attachment).
