Zach and warren both leave the coffee shop at the same time, but in opposite directions. if warren travels 7 mph faster than zach and after 7 hours they are 161 miles apart, how fast is each traveling?

Speed of Zach = 16 mph

Sspeed of Warren = 16+7=23 mph

Step-by-step explanation:

Let x be the speed of Zach in mph , the speed of Warren will be x+7 mph.

Formula to find distance :-

Then, distance covered by  Zach in 7 hours =

Distance covered by Warren =  

Then, according to the question, we have

Hence, the speed of Zach = 16 mph

The speed of Warren = 16+7=23 mph

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.
