1425 Bagels can be made in 15 hours at a rate of 95 bagels per hour. In order to solve this equation half the amount of bagels made in 2 hours to find the amount they can make in 1 hour. Next multiply the amount of bagels per hour by 15.
The answer is 85 let me explain:
All you do for the mean is add all the values(numbers) together, and then divide by the amount o f numbers.
so your number set is
87,84,86,79,84,90
so all we do is add them all together
87 + 84 + 86 + 79 + 84 + 90
which equals 510
then we divide by the amount of values (numbers) there are.
since there are 6 numbers in this data set we have to divide 510 by 6
which gives us a quotient of 85
so 85 is your answer.
The average rate of change on the interval (5, 6) is 9. So the correct option is D.
<h3>
How to find the average rate of change on the interval?</h3>
Here we want to find the average rate of change of f(x), the function on the table, on the interval (5, 6).
This is just:


I we look at the table we see that:



This is a system of equations.
If we subtract the second and first functions, we get:

From that we take two relations:

Now we can replace these two in the last equations so we get:

Now that we know the value of a:

The quadratic equation is:

Evaluating this in x = 6 we get:

And from the table we know that f(5) = 17, then the average rate of change is:

The correct option is D.
