mihalych1998 [28]
If she is making 6 costumes that need 3 7/9 yards each, the equation would be 6 x 3 7/9.

The answer to that equation would be 22 2/3.

How to get the answer:
3 x 6 = 18
7 x 6 = 42 (the seven is from the 7/9)
42/9 = 4 2/3

then add the eight teen and the 4 2/3 and you get 22 2/3.

Suppose the population of IQ scores in the town or city where you live is bell-shaped, with a mean of 104 and a standard deviati
SVEN [57.7K]

Answer:

The mean of samples of 100 IQ scores taken out from this population will have a distribution with mean M=104 and standard deviation s=3.5.  

Step-by-step explanation:

We know the population mean and standard deviation, that has a bell-shaped distribution:

\mu=104\\\\\sigma=35

The sampling distribution, the distribution of the mean of samples of size n out of this population, will have the same mean as the population mean.

\mu_M=\mu=104

The standard deviation will be related to the population standard deviation and the sample size as:

\sigma_M=\frac{\sigma}{\sqrt{N}} =\frac{35}{\sqrt{100}}=3.5

Then, the mean of samples of 100 IQ scores taken out from this population will have a distribution with mean M=104 and standard deviation s=3.5.
