Answer:
A.
Step-by-step explanation:
To check if a graph is a function, use the vertical line test. Use a ruler or straight edge, or simply imagine a vertical line. Move the line across the graph. The line should only intersect the graph at one point at any time.
B isn't a function because the line intersects the graph at two places (when x = 0).
C isn't a function because the line intersects the graph at two places (between x = -1 and x = 1).
D isn't a function because the line intersects the graph at two places (when x < -1 and when x > 1).
Only A is a function.

Answer:
52%
Step-by-step explanation:
We are told that, of all customers 65% buy a burger. This would imply that the proportion of customers who buy a burger is 0.65.
Moreover, if a customer buys a burger, the probability they buy french fries is 0.80. This implies that the proportion of customers who buy fries given that they bought a burger is 0.8.
Therefore, the proportion of customers who get a burger and fries is simply the product of the two probabilities;
= 0.65*0.8
= 0.52
Therefore, 52% of all customers get a burger and fries
