Answer:
C: 5 inches
Step-by-step explanation:
The length of the sides of the new square is the square root of the area:
s = √A = √49 = 7
The original square had sides 2 inches shorter, so they were ...
7 in -2 in = 5 in . . . . side length of original square
She has -80 because 4 withdrawalsof 50 is 200 subtract the that from 120 its -80
Answer:
Correct option:
"The distribution of the statistic in all possible samples of size <em>n</em> from a given population."
Step-by-step explanation:
The sampling distribution is a probability distribution of a sample statistic.
A sample statistic is a numerical value representing a characteristic of a sample. For example, the sample mean represents the mean value of the sample, the sample variance represent the variance of the sample. Both of these values are sample statistic.
A statistic is an unbiased estimator of the parameter value.
That is, the sample mean value can be used to estimate the value of population mean.
If various large samples are taken from a population and the sample statistic value is computed for each of these samples, then the probability distribution of theses sample statistic is known as the sampling distribution.
The mean of the sampling distribution is same as the population mean and the standard deviation of the sampling distribution is known as the standard error.
The correct option is:
"The distribution of the statistic in all possible samples of size <em>n</em> from a given population."
As the Question is not clear
But there are two possibilities
1. →→Cancelling x+2 from numerator and denominator
→→ Using the formula (a³ + b³) =(a+b)(a² - ab + b²)
Or if
→→Cancelling x-2 from numerator and denominator
Using the formula (a³ - b³) =(a-b)(a² + ab + b²)
Statement (1) appears true.
So, correct option is x²- 2 x + 4 or x² + 2 x + 4
