Answer:
Step-by-step explanation:
Sample variance when large number of samples are drawn we have tend to become a normal distribution.
Variance of the sample is different since variance
Var(x) = E(x^2)-{E(x)}^2
is the formula used for finding the variance of any sample.
But sampling distribution of variance requires repeating this process with the different samples several times.
So option A is not right
B is also not correct, C is wrong
D.The sampling distribution of the mean requires multiple samples to be compared. However, in this situation you are looking for the variance, so finding the sample variance is the same as investigating the sampling distribution of the variance.
is correct
is regions of f ◦ g(·).
<u>Step-by-step explanation:</u>
When you multiply two functions together, you'll get a third function as the result, and that third function will be the product of the two original functions.
For example, if you multiply f(x) and g(x), their product will be h(x)=f.g(x), or h(x)=f(x)g(x).
Here we have two functions, f identifies n f regions of (0, 1)d onto (0, 1)d which is equivalent to f(x) = n f. And, g identifies n g regions of (0, 1)d onto (0, 1)d which is equivalent to g(x)= n g. Now,
⇒ ( f × g ) (x ) = f(x) × g(x)
⇒
Therefore, is regions of f ◦ g(·).
Question 3) 5x-26=18x This is how the equation is written if you substitute numbers for words and x for unknown number. 18x-5x =13x divide everything by 13 to get x= -2
Question 4) 63-x=2x+3 add x to each side and subtract 3 from each side to get 60=3x divide by 3 to get x=20
Question 5) -30x= -27x-63 add -27x to each side to get -3x= -63. Divide everything by -3 to get x=21
Question 6) 12x-18= 18+13x subtract 12x from both sides to get -18=18+x subtract 18 from both sides to get x=-36
Hope this helps!
The Answer Is <span>factor by grouping</span>
Well for a line to be perpendicular to another the slope should be an opposite reciprocal, which in this case is -6/7. One example is y= -6/7x+2
