Answer:
35
Step-by-step explanation:
The theoretical probability of landing on tails is P = 0.5, and out of the 250 contestants, around 125 will win the game.
<h3>
About how many contestants will win?</h3>
The coin has two possible outcomes, so if it is a fair coin, the probability for each of the outcomes will be 0.5 (this is the theoretical probability for a fair coin, where all the outcomes have the same probability).
Now, we know that a person wins if the coin lands tails up, and the probability of landing on tails is 0.5
Then, for a sample N, we can expect that about 0.5*N of the participants win.
In this case, the sample is 250, then we can expect that:
0.5*250 = 125
Around 125 of the contestants win the game

Answer:
y = 7, x = 7
Step-by-step explanation:
11y + 13 = 90
11y = (90 - 13)
11y = 77
y = 7
2x + 6 = 20 (because 20 is half of 40)
2x = (20 - 6)
2x = 14
x=7
Answer:
The answer to your question is AD = 74
Step-by-step explanation:
Data
AB = CD = 10
BC = DE = 54
DE = 54
CD = 10
Process
From the picture we know that
AD = AB + BC + CD
Substitution
AD = 10 + 54 + 10
Simplification and result
AD = 74
