Answer: 7x + 4 y = 2
9x - 4y= 30
-------------------
16x / = 32
x= 32:16
x=2
Step-by-step explanation: 7x+4y=2
7*2 + 4y=2
14 +4y=2
4y= 2-14
4y= -12
y= -12 : 4
y= - 3
Answer:
the probability is 0.4642 (46.42%)
Step-by-step explanation:
for the events E and F such that
N(E ∩ F) = 250 and N(E) = 560
where N represents the number of elements in that set , we can use the theorem of Bayes for conditional probability .Then representing N total =N(E∪F) , we have that the probability is
P( F|E ) = P (E ∩ F)/ P(E) = [N(E ∩ F) / N total]/ [N(E) / N total ] = N(E ∩ F)/ N(E) = 250/560 = 0.4642 (46.42%)
Let's call Lyndale L and Jack J
L = J - 27
Jack has 80 fish so Lyndale has
L = 80 - 27
L = 53
Lyndale has 53 fishes.
