The scatter plot shows a positive linear trend. With the correlation Coefficient depicting a R value of 0.56. The residual plot also depicts a a randomly scattered values of the residual values. Similarly, a plot of the normal values of residuals
Answer:
C(m) = 25 + 6m and m ≥ 0.
Step-by-step explanation:
After joining the moviegoer club, Makayla charged an annual registration fee of $25. but, movie tickets are charged for members at $6.00 per ticket.
Let us assume that Makayla purchased m number of movie tickets in a year since he joined the club then the function that models the total cost for Makayla's movie ticket is given by
C(m) = 25 + 6m
The domain of the function is represented by m ≥ 0. (Answer)
