Mathematics
1 answer:
ANEK [815]1 year ago
3 0

Answer:

<u><em>-29/15</em></u>

Step-by-step explanation:

  • <u><em>Multiply 2 and 3 to get 6</em></u>
  • <u><em>-6+2/3 + 11/15</em></u>
  • <u><em>Add 6 and 2 to get 8</em></u>
  • <u><em>-8/3+11/15</em></u>
  • <u><em>LCM of 3 and 15 is 15. Convert -8/3 and 11/15 to fractions with 15 as the denominator</em></u>
  • <u><em>-40/15 + 11/15</em></u>
  • <u><em>Since -40/15 and 11/15 have the same denominator, add them by adding the numerators</em></u>
  • <u><em>-40+11 / 15</em></u>
  • <u><em>Add -40 snd 11 to get -29</em></u>
  • <u><em>-29/15</em></u>

The linear function f(x) = 0.9x + 79 represents the average test score in your math class, where x is the number of the test tak
Levart [38]

Given:

The linear function for average test score in your math class is

f(x)=0.9x+79

where x is the number of the test taken.

The linear function g(x) in the given table represents the average test score in your science class, where x is the number of the test taken.

To find:

Part A: The test average for your math class after completing test 2.

Part B: The test average for your science class after completing test 2.

Part C: Which class had a higher average after completing test 4?

Solution:

Part A:

We have,

f(x)=0.9x+79

Put x=2 in the above function, to find the test average for your math class after completing test 2.

f(2)=0.9(2)+79

f(2)=1.8+79

f(2)=80.8

Therefore, the test average for your math class after completing test 2 is 80.8.

Part B:

From the given table it is clear that g(x) =79 at x=2.

Therefore, the test average for your science class after completing test 2 is 79.

Part C:

Put x=4 in f(x), to find the test average for your math class after completing test 4.

f(4)=0.9(4)+79

f(4)=3.6+79

f(4)=82.6

From the table it is clear that the value of g(x) is increased by 1 as x is increased by 1. So, the value of function g(x) at x=4 must be 1 more than 80.

g(4)=81

It is clear that,

82.6>81

Therefore, math class had a higher average after completing test 4.
