the linear function f(x) = 0.2 + 79 represents the average test score in your math class where x is the number of test taken. The linear function represents the average test score in your science class where x is the number of test taken x | g(x) 1 | 86 2 | 84 3 | 82 Part a: determine the test average for you math class after completing test 2 part b: determine the test average for your science class after completing test 2 part c : which class had the higher average after completing test 4 show work to support your answer

A) f(2) = 79.4

B) g(2) = 84

C) Science class had higher average

Step-by-step explanation:

The average score in your math class is given by the equation:

f(x) = 0.2x + 79

where x represents the number of tests taken.

For 2 test, substitute x=2 into the given equation.

f(2) = 0.2(2) + 79

f(2) = 0.4 +79

f(2) = 79.4

Average score of science class can simplify be determined by seeing the table. We can see that for after taking 2 tests, the average score is 84.

g(2) = 84

For Math class, average score after 4 classes is:

f(4) = 0.2(4) + 79

f(4) = 0.8 + 79

f(4) = 79.8

As the average score of science class is decreasing by 2 after increasing taking each test, average score after 4 test will be 80.

g(4) = 80

Science class had higher average

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.
