Question

Use the table to find the number of miles x you need to bike on friday so that the mean number of miles biked per day is 5

Answer 1

Friday needs 11 bikes

Explanation:

Mean = (summation of all the numbers)/the total number of the given data

(summation of all the numbers)

= 3.5+5.5+0+5+x

(summation of all the numbers)

= 14+x

the total number of the given data

=5

Mean= 5

Mean= (summation of all the numbers)/the total number of the given data

5= (14+x)/5

25= 14+x

25-14=x

11= x
