An employee spilled coffee making the entry for hour 2 unreadable. the employee knows the mean for the data in the table is 21 how many prescriptions were filled during hour two

13

Step-by-step explanation:

We have been given that mean = 21 and total number of hours = 8

Let the number of prescriptions filled during hour two be x

Multiply both sides by 8

Cancel out the 8's on the top and bottom of the right side

Subtract 155 from both side

168-155=155+x-155

Cancel out +155 and -155 from the right side

13 = x

Flip the sides

x = 13

So, the number of prescriptions filled during hour two = 13

-4

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
