Chitchat wireless charged 0.30 per minute plus a monthly base fee in September Maggie used 120 minutes and her bill was $51 write and solve an equation to find the cost of Maggie uses 165 minutes in October

$64.50

Step-by-step explanation:

First you need to find how much the fee is from the information on the month of September:

1.) Find out how much the minutes cost so you can subtract that number from the total of the bill to find how much the fee was

$36

$51 - $36 = $15

This means the monthly base fee is $15

Now all you have to do is figure out how much 165 minutes cost then add the monthly fee of $15

$49.50

$49.50+$15= $64.50

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
