1.) A group of students took a Final Exam. Their scores are as follow 18, 10, 12, 8, 16, 18, 20, 6, 16, 12, 15, 7.
(Round your answers to one decimal place). Gl6
a.) Find the Average:
b.) Find the Standard Deviation:
c.) Create the Normal Distribution Graph.

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

hey there : ) your answer would be a.
