Answer:
The standard error is 11.
Step-by-step explanation:
Given : If the standard deviation of a normally distributed population is 22.0 and we take a sample of size 4.
To find : The standard error ?
Solution :
The standard error formula is

Where,
is the standard deviation of a normally distributed population
n=4 is the sample size
Substitute the value,



Therefore, the standard error is 11.
You take 50/4 which equals 12.5
so now you say “well one sub is 2.95”
take that and multiply it by 12
12 x 2.95 = 35.4
then you take 2.95 and divide it by 2 that is 1.48
so now you take 35.4 + 1.48
the cost should be 36.88
Answer:
90 degrees?
Step-by-step explanation:
im just guessing?
Find the gradient/slope
6-6/5-(-2) deltaY/deltaX
=0 shows its a straight line
Delta X = 7
Distance between P & M = 7 units
If M is the midpoint then Q is 7*2 units
Away from P (14 units away)
-2 + 14 units = 12 x-coordinate
Hence the coordinates of Q
= (12,6)
FINAL ANSWER:
Coordinates of Q (12,6)
Answer:
Yes!
Step-by-step explanation:
In Pythagorean Triples, the two legs always have to add up to be a greater number than the hypotenuse. In this case, 12 and 16 are the legs and 20 is the hypotenuse. The sum of 12 and 16 is 28. That is more than 20, so 12, 16 and 20 make a right triangle. I hope this helps you!
