Answer:
Step-by-step explanation:
Going by variance size, Estimator Z is relatively more efficient than Estimator Y and Estimator Y is relatively more efficient than Estimator X.
By bias, estimators X and Y would have been preferred to estimator Z but if estimator Z has small bias, it should be more efficient than X and Y, especially as it has the smallest variation (variance) from the true value of the variable.
Answer:
The smallest value of p+q is 11
It happens when p = 6 and q = 5.
=======================================================
Explanation:
Let's factor 180 in such a way that exactly one factor is a perfect square.
I'll ignore the trivial factor of 1.
Here are the possible factorizations we could go with:
180 = 4*45
180 = 9*20
180 = 36*5
Those factorizations then lead to the following
Then we have
p+q = 2+45 = 47
p+q = 3+20 = 23
p+q = 6+5 = 11
The smallest value of p+q is 11 and it happens when p = 6 and q = 5.
Side note: p+q is smallest when we go with the largest perfect square factor.
If you make both of the denominators the same this can be a lot simpler.
1 1/2 divided by 1/4
1 2/4 divided by 1/4
6/4 divided by 1/4
How many times does 1/4 go into 6/4?
6
Hope this helps :)
Answer:
maths
this too hard idk like C idk bc C is betwwed B and D
the answer is 45
simply square root 2025 on a calculator to find it
Square root is the result of a number multiplying itself
