Answer:
The expected number of people identified as telepathic if everyone is just guessing in a sample of 500 = 100 (option B)
Step-by-step explanation:
If everyone is just guessing, the number of right answers will be due to random chance. And if that is so, the central limit theorem explains that the sample proportion of a random, independent sample is approximately equal to the population proportion or the overall proportion due to random chance.
That is,
p = p₀ = 0.20
Expexted number of successes from a sample = Mean = μ = np
where n = sample size = 500
p = sample proportion = 0.20
Mean = 500 × 0.20 = 100

Answer:
1. 5w+2(w+5) = 5w+2w+10
7w+10-6w+2(9w+3) = 1w+18w+10+6
19w+16+38-4w = 15w+54
15w+54
2. 3(5w+18)
5w(3)= 15w
18(3)=54
15w+54
