Respuesta :

Answer:

86.86

Step-by-step explanation:

Another word for mean is average.  To find the mean or average, we add up all the numbers and then divide by the number of numbers

There are 7 scores

Mean = (88+91+89+94+90+64+ 92)/7

         = 608/7

         =86.85714286

To 2 decimal places ( we have to round to be accurate to 2 decimal places)

         86.86
