Answer:
The same number raised to the pawed of one
Step-by-step explanation:
Any number to the power if one will be the same number. It won't change.
Answer:
C, F hope this helps
Step-by-step explanation:
Alright, so there are 4 reindeer to fill 3 different positions, which is a permutation. If you have a calculator, this can be calculated by finding the nPr function and filling in 4P3 (4 pick 3).
If you don't have a calculator, you can use the formula:
n! / ((n-r)!)
where n is the total number in the set and r is the number chosen
solving that formula:
4! / (4-3)! = 4*3*2*1/1 = 24
Either way, you get the answer of 24.
Answer:
B. Sample mean used to estimate a population mean.
C. Sample variance used to estimate a population variance.
D. Sample proportion used to estimate a population proportion.
Step-by-step explanation:
This is because the mean of the sampling distribution of the mean tends to target the population mean. Also, the mean of the sampling distribution of the variance tends to target the population variance.
This means that the sample mean and variance tend to target the population mean and variance, respectively, instead of systematically tending to underestimate or overestimate that value. This is why sample means and variances are good estimators of population means and variances, respectively. This is also true for proportions but not true for medians, ranges and standard deviations.
