morgan has 42 inches of rope, Malcolm has 4 feet of rope and Roberto has 2 yards of rope express the total length of rope the three friends have in inches, feet, and yards.

1) Total length in inches = 162 inches

Step-by-step explanation:

express the total length of rope the three friends have in inches, feet, and yards.

2) Total length in Feet = 13.5 feet

3)Total length in yard = 4.5 yard

a) Total length in inches

Morgan has 42 inches of rope

Malcolm has 4 feet of rope

Convert to inches

1 foot = 12 inches

4 feet = 4 × 12 inches

= 48 inches

Roberto has 2 yards of rope

Convert to inches

1 yard = 36 inches

2 yards = 2 × 36 inches

= 72 inches

Hence, the total length of rope in inches

= (42 + 48 + 72)inches

= 162 inches

2) Total length in Feet

1 inch = 0.0833 feet

162 inches = 162 × 0.0833 feet

= 13.5 feet

2) Total length in yard

1 inch = 0.0278 yard

162 inches = 162 × 0.0278 yard

= 4.5 yard

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.
