Answer:
The correct option is A.
Step-by-step explanation:
The equation of best fit is
Where, y is time needed to produce batches of different numbers of items and x is number of items in a batch.
The slope intercept form of a line is
Where, m is slope and b is y-intercept.
On comparing both equations we get m=8 and b=20.
It means initial time is 20 or it takes about 20 minutes for the equipment to warm up.
Since m=8, so the production time increases by 8 minutes as the number of items in a batch increases by 1.
Therefore, the correct option is A.

Answer:
Cost of per session the average rate is $45.
Step-by-step explanation:
It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.
It is required to find what is the cost per session.
Step 1 of 1
It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.
To find the cost of per session calculate the average rate.
Now let $f(x)$ be the cost per session use the for the average rate of change, and the input value is the number of personal traings x.
Now substitute, $125 for , 260 for
for
and 5 for
then,
Cost of per session the average rate is $45.
