Final Grade An instructor grades exams,20% ; term paper,10% ; and final exam,70% . A student had grades of 73, 83, and 92, respectively, for exams, term paper, and final exam. Find the student's final average. Use the weighted mean. Use a graphing calculator.

Step-by-step explanation:

Exams:                         20% times 73  =        14.60

Term papers:               10% times 83              8,3

Final:                            70% times 92           64.4

Final Grade (Weighted Average) =               87.3

All the grades were figured as follows

Final 92 * 70/100  = 6440/100 = 64.4

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
