Answer:
Z and B are independent events because P(Z∣B) = P(Z).
Step-by-step explanation:
After a small online search, I've found a table to complete this problem, that we can see below.
For two events Z and B, we have:
P(Z|B) = probability of Z given that B
such that:
P(Z|B) = P(Z∩B)/P(B)
So, two events are independent if the outcome of one does not affect the outcome of the other.
So, if the probability of Z given B is different than P(Z) (the probability of event Z) means that the events are not independent.
So Z and B are independent if the probability of Z given B is equal to the probability of Z.
P(Z|B) = P(Z)
In the table we can see:
P(Z|B) will be equal to the quotient between all the cases of Z given B (126) and the total cases are given B (280)
P(Z|B) = 126/280 = 0.45
Similarly, we can find P(Z):
And P(Z) = 297/660 = 0.45
So we can see that:
P(Z|B) = P(Z)
Thus, B and Z are independent.
Answer:
Part A: $55.50
Part B: 52 hamburgers(sorry if I am wrong for part b but I think it is right)
Step-by-step explanation:
Part A: $14.50 x 3= $43.50 + 24 x $0.50= $12=
($ earned per hrs x hrs worked)+ ($ per hamburger sold x times amount)
Hence $43.50 + $12= $55.50.
Part B: $14.50 x 6.5 = $94.25 $120 - $94.25= $25.75
($ earned per hrs x hrs worked x x hrs worked) ($ earned - $ earn from shif
$25.75/0.50=51.5 (51.5 rounded to nearest burgers is 52 burgers)
Hence answer is 52 burgers.
