7. A restaurant owner wants to see if there is a relationship between the amount of sugar in some food items on her menu and how popular the items are.
She creates a scatter plot to show the relationship between amount of sugar in menu
items and the number of orders for those items. The correlation coefficient for the
line of best fit is 0.58.
a. Are the two variables correlated? Explain your reasoning.
b. Does either of the variables cause the other to change? Explain your reasoning.

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x
