Answer:
The class width is 20
Step-by-step explanation:
In a frequency or a relative frequency distribution the class width is calculated as the difference between the lower or upper class limits of consecutive classes. A point to note is that all the categories or classes usually have the same class width.
We use the first two classes to calculate the class width by using their respective upper limits;
Class width = 89 - 69
Class width = 20
Answer:
Given : The linear function f(x) = 0.2x + 79 represents the average test score in math class, where x is the number of the test taken.
The linear function g(x) represents the average test score in your science class, where x is the number of the test taken.

To Find : test average for math class after completing test 2
test average for science class after completing test 2
Which class had a higher average after
completing test
Solution:
f(x) = 0.2x + 79
=> f/2) = 0.212) + 79 = 79.4f(x) = 0.2x + 79
=> f(4) = 0.2(4) + 79 = 79.8
test average for math class after completing test 4 = 79.8 =
1 1 2 3 4 g(x) 86 84 82 80
Х
g(2) = 84
test average for science class after completing test 2 = 84
g(4) = 80
test average for science class after completing test 4 = 80
80 > 79.8science class has more average than
MARK AS THE BRAINLIEST
