Answer:
The right answer is : f(-4)=5
There are a total of 10 fishermen as stated in the given. The probability that a chosen fisherman liked salmon is 3/10. Also, the probability that a fisherman liked bass is 2/10. By using the conjunction "or" we add the probabilities of these events to arrive with the answer giving us 5/10 or 1/2. The answer is letter D.
Answer:
The answer to your question is There were sold 166 adult tickets and 294
children tickets.
Step-by-step explanation:
Data
Total number of seats = 460
cost for adults = a = $52
cost for children = c = $26
Total cost = $16276
Process
1.- Write equations to solve this problem
a + c = 460 Equation l
52a + 26c = 16276 Equation ll
2.- Solve the system of equation by substitution.
-Solve equation l for a
a = 460 - c
-Substitute a in equation ll
52(460 - c) + 26c = 16276
-Expand
23920 - 52c + 26c = 16276
-Simplify
-26c = 16276 - 23920
-26c = -7644
c= -7644/-26
c = 294
3.- Find a
a = 460 - 294
a = 166

I hope this helps you
Step-by-step explanation:
y=x+9
x=y-9 f^-1 (x)= x-9
x=5 f^-1 (5)=5-9 = -4
f (f^-1))=f (-4)=?
x= -4
f (-4)=-4+9
f (-4)= 5
