Answer:
50
Step-by-step explanation:
Answer:
O(4.-1.5) should be the answer
Okay so I'm guessing that they are two different formulas the f(x)= 3x and the f(x)= -5x-2. If that's is true then you would just have to plug in -2 to the x's. So then it would be f(x)= 3(-2) which if you solve it would give you f(x)= -6 and for the second one it would be f(x)= -5(-2)-2 so then you would solve for it and get f(x)= 8.
The probability that ticket was a student ticket is 42 / 132
Recall :
Probability = Required outcome / Total possible outcomes
To obtain the probability that the ticket sold for space force is a student ticket :
Total possible outcomes = number of ticket sold for space force = 132 tickets
Required outcome = number of student tickets sold for space force = 42
Hence,
P(space force | student ticket) = 42 / 132

I'm not 100% sure it's correct but I tried my hardest and it's a combination of elimination and substitution
