The equation is
Concept Used:
Graph reading
Calculation:
Concluding from the graph, the graph does have a maximum and a minimum.
The maximum is at (0,200) and the minimum is at (4,0).
The maximum indicates the total distance, which is 200 miles.
The minimum indicates the total time, in hours, it will take, which is 4hours.
Conclusion:The maximum is at (0,200) and the minimum is at (4,0).

- Café Michigan's manager, Gary Stark, suspects that demand for mocha latte coffees depends on the price being charged. Based on historical observations, Gary has gathered the following data, which show the numbers of these coffees sold over six different price values: Price Number Sold $2.70 765 $3.50 515 $2.00 990 $4.30 240 $3.10 325 $4.00 475 Using simple linear regression and given that the price per cup is $1.85, the forecasted demand for mocha latte coffees will be cups (enter your response rounded to one decimal place).arrow_forwardGiven the correlation coefficient (r-value), determine the strength of the relationship.
