What is the means-to-MAD ratio of the two data sets, expressed as a decimal?Data set Mean Mean absolute deviation (MAD)
1 10.7 2.4
2 13.7 2.5

Answers

You have to calculate two separate measures, one for each set.The mean-to-MAD ratio is the mean divided by the MAD, i. e. mean / MAD. For the set 1, mean = 10.7 and MAD = 2.4, then mean / MAD = 10.7 / 2.4 = 4.4583. For the set 2, mean = 13.7 and MAD is 2.5, so mean/ MAD = 13.7 / 2.5 = 5.480.

Keith has $500 in a savings account at the bank at the begging of the summer. He wants to have at least $200 in the account by the end of summer. He withdraws $25 each week for food, clothes, and movie tickets. How many weeks can Keith withdraw money from his account?

Answers

Answer: 12 weeks

Step-by-step explanation:

If Keith wants tgo have at least 200 in his account at the end of summer you need to minus it from the original 500 to make a new total.  

Now you will have $300 to work with.  

Since Keith needs $25 a week you will divide your new total ($300) by 25 and it will give you the number of weeks he can sustain this budget.

300/25=12
