the equation of the line of best fit is y = 0.755x + 11.339. based on the line of best fit, approximately how many customers are predicted to use a card to pay on a day when 90 customers pay by cash? a. 68 b. 79 c. 92 d. 104
Answer
Explanation:
Step1: Identify the variables
The equation of the line of best - fit is $y = 0.755x+11.339$, where $x$ is the number of customers paying by cash and $y$ is the number of customers paying by card.
Step2: Substitute the value of $x$
We are given that $x = 90$. Substitute $x = 90$ into the equation: $y=0.755\times90 + 11.339$.
Step3: Calculate the value of $y$
First, calculate $0.755\times90=67.95$. Then, $y=67.95 + 11.339=79.289\approx79$.
Answer:
B. 79
