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

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
