Since 2 movie tickets equal to $15 I am only left to assume we are adding $7.50 to every movie ticket, going by that logic
7.50x4=30
Answer: It would cost $30 for 4 movie tickets.
-3 -2 -1 0 1 2 3. If that’s confusing, it’s 0.
Answer:
118°
Step-by-step explanation:
Line b is a perpendicular bisector so 90°+28°=118°
Answer:
The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.
I guess that we want to find the expected value in one spin:
number 1: wins $1
number 2: wins $3
number 3: wins $5
number 4: wins $7
number 5: losses $8
number 6: loses $8
The expected value can be calculated as:
Ev = ∑xₙpₙ
where xₙ is the event and pₙ is the probability.
We know that the probability for all the events is 1/6, so we have:
Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0
So the expected value of this game is $0, wich implies that is a fair game.
