Answer:
The value of μ will be "0.82".
Step-by-step explanation:
The given question is incomplete. Please find attachment of the complete question below.
The given three random samples are 0.8, 0.95 and 0.7.
Now,
⇒
On substituting the estimated values, we get
⇒
⇒
⇒
It will not rational here, considering the equivalent significance, since the sampling amount for sample 3 becomes somewhat big 200.
Answer:
In the given figure the point on segment PQ is twice as from P as from Q is. What is the point? Ans is (2,1).
Step-by-step explanation:
There is really no need to use any quadratics or roots.
( Consider the same problem on the plain number line first. )
How do you find the number between 2 and 5 which is twice as far from 2 as from 5?
You take their difference, which is 3. Now splitting this distance by ratio 2:1 means the first distance is two thirds, the second is one third, so we get
4=2+23(5−2)
It works completely the same with geometric points (using vector operations), just linear interpolation: Call the result R, then
R=P+23(Q−P)
so in your case we get
R=(0,−1)+23(3,3)=(2,1)
Why does this work for 2D-distances as well, even if there seem to be roots involved? Because vector length behaves linearly after all! (meaning |t⋅a⃗ |=t|a⃗ | for any positive scalar t)
Edit: We'll try to divide a distance s into parts a and b such that a is twice as long as b. So it's a=2b and we get
s=a+b=2b+b=3b
⇔b=13s⇒a=23s
Here are the laws of exponents:
Hope that helps :)
Answer:
This verified guy is wrong, and all I can say is I resubmitted twice and it's not "He should use the median because it's the center of data" or "He should use the mean because there are no outliers that affect the mean."
Step-by-step explanation:
Actually, it's MEDIAN because there ARE outliers that affect the MEAN. If you take the mean, average, then the $2.5 M house will raise the mean.
It’s 66 units to 2 because you have to line up the numbers with the dot on the grid
