Consider the following statements about a particular traditional class of statistics students at state u related to discrete and continuous variables. which of the following is a true statement? check all that apply. the number of students in the class is a discrete variable. the average age of the students in the class is a continuous variable. the room number of the class is a continuous variable variable. the average weight of the students is a discrete variable. a student's gpa is a continuous variable.

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
