Answer:
A. unbiased estimator.
Step-by-step explanation:
In Statistics, an estimator is a statistical value which is used to estimate a parameter. Parameters are the determinants of the probability distribution. Therefore, to determine a normal distribution we would use the parameters, mean and variance of the population.
A function of random variables used to estimate a parameter of a distribution is an unbiased estimator.
An unbiased estimator is one in which the difference between the estimator and the population parameter grows smaller as the sample size grows larger. This simply means that, an unbiased estimator captures the true population value of the parameter on average, this is because the mean of its sampling distribution is the truth.
Also, we know that the bias of an estimator (b) that estimates a parameter (p) is given by; 
Hence, an unbiased estimator is an estimator that has an expected value that is equal to the parameter i.e the value of its bias is equal to zero (0).
<em>Generally, in statistical analysis, sample mean is an unbiased estimator of the population mean while the sample variance is an unbiased estimator of the population variance.</em>
The answer you are looking for is 3.
To find this, you must first distribute the 3 into the parenthesis. 3 x 9 = 27 and 3 x 4 = 12.
Next, you subtract 12 from 27. 27 - 12 = 15.
Finally, divide 15 by 5 to get your final answer as 3.
I hope this helps!
To find multiples of a number, simply multiply the number by any whole number. So, I've calculated the first ten mutliples of 16984 for you.
1 * 16984 = 16984
2 * 16984 = 33968
3 * 16984 = 50952
4 * 16984 = 67936
5 * 16984 = 84920
6 * 16984 = 101904
7 * 16984 = 118888
8 * 16984 = 135872
9 * 16984 = 152856
10 * 16984 = 169840
Hope this helps! :)
Answer:
x = 5
Step-by-step explanation:
x² - 5x = 0
(x² - 5x) /x = 0/x
x²/x - 5x/x = 0
x - 5 = 0
x = 5
Check:
x² - 5x = 0
5² - 5*5 = 0
25 - 25 = 0
Subtract negative = add
88 + 35 = 123
The solution is 123
