Not everyone pays the same price for the same model of
a car. the figure illustrates a normal distribution for the
prices paid for a particular model of a new car. the
mean is $17,000 and the standard deviation is $500. in
questions 11 - 22 use the 68 - 95 - 99.7 rule, illustrated
in the figure to the right to find the percentage of buyer
who paid
number of car buyers
6. between $16,000 and $18,000.
7. between $17,000 and $18,000.
8. between $16,500 and $17,000.
9. between $17,000 and $18,500.
10. more than $18,000.
11. less than $16,500.

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
