Answer:
a) 3/5 < 4/5
b) In general if two fractions have the same denominator, then whichever fraction has the numerator closer to its denominator will be the largest fraction.
c)
<em>or</em> ![\frac{7}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B10%7D%3C%5Cfrac%7B9%7D%7B15%7D)
Step-by-step explanation:
a) 3/5 < 4/5
Flip the sign and the placement of the fraction so 3/5 is less then 4/5.
b) In general if two fractions have the same denominator, then whichever fraction has the numerator closer to its denominator will be the largest fraction.
c) We need to change the denominators to a common denominator to compare the size of the two fractions:
×
= ![\frac{21}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B30%7D)
×
= ![\frac{18}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B30%7D)
The common denominators of the two fractions is 30. Comparing the two fractions:
<em>or</em> ![\frac{18}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B30%7D%3C%5Cfrac%7B21%7D%7B30%7D)
so we get:
<em>or</em> ![\frac{7}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B10%7D%3C%5Cfrac%7B9%7D%7B15%7D)
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
