Answer (all) will mark 1) if a plane is flying at 40 mph while another plane is flying at 100 mph and they are 200 miles apart, how long will it take them to collide? 2) ivan and kate live 40 miles apart. if ivan started pedaling towards kate at 8: 00 a. m. at a steady 12 mph while kate left to meet ivan at 9: 30 a. m. but rode at 16 mph, at what time will they meet? 3) a truck with a heavy load drove from boston to new york at 40 mph. after unloading, it returned from new york to boston at a speed of 60 mph. what was its average speed for the whole trip?

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.
