c
for exponents it's always multiplication with each number
Ex.
5 exponent 4
5 x 5 x 5 x 5
Answer:
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
Where and
Since the distribution for X is normal then the we know that the distribution for the sample mean is given by:
And the standard error is given by:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
Where and
Since the distribution for X is normal then the we know that the distribution for the sample mean is given by:
And the standard error is given by:
Answer:
D
Step-by-step explanation:
The difference is 6 and because 6+4=10( 1 wk ),10+4=14( 2 wk ),14+4=18( 3 wk ),18+4=22( 4 wk ),22+4=26( 5 wk ).
Well, apologies if this is wrong but in my opinion, I think it's that The angles do not change. This is because the angles are alright staying in the same place. I don't understand much about angles but it makes the most sense to me.
Point-slope form is:
y - y1 = m (x - x1)
So the correct form for that equation would be:
y - 4 = 3 (x - 2)
So the correct equation is the first one.
