In Exercises 3-6, think of each segment in the diagram as part of a line. All the angles are right angles. Which
line(s) or plane(s) contain point B and appear to fit the
description? (See Example 1.)
B
D
A
G
H
E
3. line(s) parallel to CD
4. line(s) perpendicular to CD
5. line(s) skew to CD
6. plane(8) parallel to plane CDH

What is the equation of the line in point-slope form? y+ 4 = 1/2(x+4) y-4 = 1/2(x + 4) y-0 = 2(x - 4) y-4 = 2(8-0)

Quadrilateral abcd in the figure below represents a scaled-down model of a walkway around a historic site. quadrilateral efgh represents the actual walkway. abcd is similar to efgh. what is the total length, in feet of the actual walkway?

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
