Here is the work! The zeros of the graph are at -1 and 3
Answer:
B.
Step-by-step explanation:
Point estimate is always at the center of the interval.
You can find it by averaging the endpoints:
p(hat) = (0.028 + 0.086)/2 = 0.057
W = 1+15*l
(The number of games they won= 1+15* the number of games they lost.)
Add -7y and divide both sides to get one solution (0.20588)
