Cole's Computer Company charges $50 for a service call to your home to repair your computer system, and he charges $12 per hour, h, for labor for any repair. Cole uses this formula to calculate the total cost, t. 50 + 12h = t

Mr. Greene paid Cole a total of $86 for a repair. How many hours did it take to finish the job?

Group of answer choices

a. 3

b. 7

c. 5

d. 4

3 hours

Step-by-step explanation:

50+12h=86

-50 on both sides

12h=36

divide by 12 on both sides

h=3

3 hours

Step-by-step explanation:

50 + 12h = 86

12h = 36

h = 3

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.  

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
