Hannah biked the following number of miles in four days. How many miles would she need to bike on the fifth day to have a mean of 5.2 miles per day?

6, 3, 4, 3

mean*5= sum of days

5.2*5=6+3+4+3+X

To find the answer, you will need to calculate the total number of miles Hannah biked in four days and then determine how many miles she would need to bike on the fifth day to achieve an average of 5.2 miles per day.

To calculate the total number of miles Hannah biked in four days, simply add up the given numbers:

6 + 3 + 4 + 3 = 16

Hannah biked a total of 16 miles in four days.

To find out how many miles she would need to bike on the fifth day to have a mean of 5.2 miles per day, you need to consider the total number of days and the desired average.

Since Hannah has biked for four days already, she will have a total of 5 days when including the fifth day. The desired average is 5.2 miles per day.

To find out how many miles Hannah would need to bike on the fifth day, you can use the formula:

Total miles = Average miles per day * Total number of days

Let's plug in the given information:

Total miles = 5.2 * 5

Total miles = 26

Hannah would need to bike a total of 26 miles in the five days to have a mean of 5.2 miles per day.

To find the number of miles she would need to bike on the fifth day, subtract the total miles she has already biked from the desired total miles:

26 - 16 = 10

Hannah would need to bike 10 miles on the fifth day to have a mean of 5.2 miles per day.
