You have to find the mean.
Add up all the points from the assignments and the 80.
Then Divide. For example, if there are 23 assignments in the grade book, divide by 23.
Now you have your final grade.
Example: 80+ 76 + 59 + 79 = 294
There are four assignments so you divide by four: 294÷4= 73.5
Final grade is 73.5
I hoped this helped.
Answer: The function that models the distance they drive is
f(x) = 50x + 20 where x is the time in hours
reasonable domain: 0 ≤ x ≤ 3
Step-by-step explanation:
examples:
95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.
120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.
There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t
20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.
120 = 5(2.4) The whole trip took 2.4 hours.
Answer:
(-2,4) (4,2) (4,-3) (6,3) parallelogram
Step-by-step explanation:
its all just rise/run between all the points to find the slope.
Step-by-step explanation:
The mean is- 100 ÷ 5= 20
The median is- 15
hope it helps!
