Step-by-step explanation:

1) The values provided in the table need to be graphed in coordinate pairs, with time on the x-axis and number of drinks on the y-axis. For example, at 11am, 20 drinks were sold, so the point would be marked on the graph where the lines for 11am and 20 drinks intersects. The same goes for the remaining values in the table.

2) As shown in the axis titles on the provided blank graph, the variables are time and number of drinks.

3) Since the slope of the graph is positive, it shows a positive correlation.  The r-value is around 0.9 and is closer to 1.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
