It takes hank 40 minutes (2/3 hours) to mow a lawn. penny can mow the same size lawn in 30 minutes (1/2 hour). hank and penny form a small lawn care company and have contracts for 7 lawns of the same size previously mentioned. how long should it take both of them working together to mow the 7 lawns? (hint: find a combined hourly rate of ""lawns per hour"" for hank and penny

2 hours

Step-by-step explanation:

Given: It takes Hank minutes hours to mow a lawn. Penny can mow the same size lawn in minutes hours. Hank and Penny form a small lawn care company and have contracts for lawns of the same size previously mentioned.

To Find: How long should it take both of them working together to mow the   lawns.

Solution:

Time taken by Hank to mow the lawn

Time taken by Penny to mow the lawn

Total lawns to be mowed

Let time taken by Hank and Penny to mow one lawn

time taken to mow lawns

Hence it will take  by Hank and Penny to mow lawns

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.
