Assuming that the drug has no​ effect, so that the probability of nausea was 0.0124​, find the mean and standard deviation for the numbers of people in groups of 828 that can be expected to experience nausea.

11.

Step-by-step explanation:

Given that the drug has no effect and that the probability of nausea was 0.0124, to find the mean and standard deviation for the numbers of people in groups of 828 that can be expected to experience nausea, the following calculation must be performed:

828 x 0.0124 = X

10.26 = X

Thus, the number of people who may feel nauseous after using the drug in question is 11 individuals.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
