If you and a friend get a job painting houses for a summer job. You can paint a room twice as fast as your friend. If you can paint a room in 4 hours, how many hours
would it take for your friend to paint a room alone?

8 hrs

Step-by-step explanation:

4*2=8 i think

Scenario 1: Assume that you paint a room by yourself in four hours.

Then your friend would take eight hours.

Scenario 2: If it took both you and your friend 4 hours to paint a room, then that means that you would have taken approximately 1.3 hours and your friend approximately 2.6 hours to paint that specific room.

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.
