Find the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given questions. Listed below are the highest amounts of net worth (in millions of dollars) of all celebrities. 1. What do the results tell us about the population of all celebrities?
2. Based on the nature of the amounts, what can be inferred about their precision?

250 200 185 175 165 165 150 150 150 150

Mean = 174

Median = 165

Mode = 150

Range = 100

Mid-range= 165-150= 15

1) only few population of the celebrities have high net-worth

2) very low precision as their is a wide range in the variation of their net worth

Step-by-step explanation:

250 200 185 175 165 165 150 150 150 150

Arranged in ascending order =

150 150 150 150 165 165 175 185 200 250

Mean = (150+ 150 +150 +150 +165 +165 +175+ 185 +200 +250)/10

Mean = 1740/10

Mean = 174

Median =( 165+165)/2

Median = 165

Mode = 150

Range = 250-150

Range = 100

Mid-range= 165-150= 15

1) only few population of the celebrities have high net-worth

2) very low precision as their is a wide range in the variation of their net worth

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130

welcome!

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
