A farmer determines that, on average, his chickens lay a total of 16 eggs each day. A random sample of 10 days was taken and the mean number of eggs was determined. Let u = the true mean number of eggs the chickens lay
each day. Which of the following values for the sample mean is the least likely to occur?
A.15
B.16
C.17
D.18

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

the answer is d

step-by-step explanation:

it would be 6xy and -16xy.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
