Answer:
Domain is
Average rate of change of bacteria per minute is -3333.33.
Step-by-step explanation:
Domain is the possible values of .
From the graph, it's clear that the values ranges from 0 to 18 as the end points of the graph are
and
So, domain of the function is .
Now, average rate of change is negative as there is bacteria decay.
Average rate of change is given as the negative ratio of y intercept to the x intercept.
Here, x-intercept is 18 and y-intercept is 60000.
So, average rate of change is given as,
Therefore, average rate of change of bacteria per minute is -3333.33.
Using weighted average, it is found that she should score 67% on the computer science test.
- The weighted average is given by <u>each proportion multiplied by it's score</u>.
In this problem, the proportions and scores are given by:
- Proportion of 32% = 0.32 for a score of 300.
- Proportion of x for a score of 200.
- Proportion of 46% = 0.46 for a score of 300 + 200 = 500.
Then
She should score 67% on the computer science test.
