what is 0.54 as a simplified fraction | Wyzant Ask An Expert
2014年9月18日 · .54 is another way of writing 54 hundredths, or as a fraction, 54/100. Asking for a simplified fraction is asking you to reduce the numerator and denominator by any common terms. 54 and 100 are both divisible by 2, so we get to 27/50.
Find the z-score for which the area to its left is 0.54.
z score of slightly more than 0 will have 0.54 area to the left. Use a calculator with a statistics function or look it up on a z table. Several websites have online z tables or calculators. But you should get 0<z<1 . if z=1, it would have 0.82 as the area to the left.54 is far closer to .5 than to .82, so z will be far closer to 0 than to 1.

In a large population, 54 % of the people have been vaccinated
2020年6月14日 · The probability in the large population that a randomly selected person IS NOT vaccinated = 1 - 0.54 = 0.46. Since the 3 randomly selected people are independent, the probability that they all are not vaccinated is 0.46^3, so the probability that at least one of them has been vaccinated is 1 - 0.46^3.
