Parking at a large university has become a very big problem. University administrators are interested in determining the average

parking time (e.g. the time it takes a student to find a parking spot) of its students. An administrator inconspicuously followed 300 students and carefully recorded their parking times. Identify the population of interest to the university administration.
a. The 250 students that data was collected from.
b. The entire set of students that park at the university.
c. The entire set of students, faculty and staff that park at the university.
d. The students that park between 9 and 10 A.M on wednesday.

Answer:

b. The entire set of students that park at the university.

Step-by-step explanation:

Since the University is interested in determining the average parking time of its students, the population of interest is the entire set of students that park at the university.

The correct option is B.

Note that the 300 students whose parking time was recorded forms a sample of the population under study.

5. In the diagram shown below, BC is drawn tangent
Tatiana [17]

9514 1404 393

Answer:

 (2)  72°

Step-by-step explanation:

In this geometry, the angle at the tangent is half the measure of the intercepted arc.

  ∠CBD = (arc BD)/2 = 144°/2

  ∠CBD = 72°

__

<em>Additional comment</em>

Consider a point X anywhere on long arc BD. The inscribed angle at X will have half the measure of short arc BD, so will be 144°/2 = 72°. This is true regardless of the position of X on long arc BD. Now, consider that X might be arbitrarily close to point B. The angle at X is still 72°.

As X approaches B, the chord XB approaches a tangent to the circle at B. Effectively, this tangent geometry is a limiting case of inscribed angle geometry.

Consider the plot created from the residuals of a line of best fit for a set of data.
Naddika [18.5K]

Answer:

No, the points are in a linear pattern.

Step-by-step explanation:

Residual plot is a graph that shows the residuals on the vertices. The y-axis has residual values and x-axis has independent variables. The horizontal axis shows the independent variables to determine the best fit for a set. The graph given is in a linear pattern. The random pattern shows that linear model is good fit.

1. A resident lot has the shape of a parallelogram. Its base measures 20 meters. The distance between the
castortr0y [4]

Answer:

160 m²

Step-by-step explanation:

Given :

A parallelogram shaped lot :

Base of lot = 20 m

Distance between parallel sides, = height of lot = 8 m

The area of the lot can be obtained using the area formula of a parallelogram :

Area = base * height

Area = 20 m * 8 m

Area = 160 m²
