Answer:
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 variable of interest of a population, and for this case we know the following conditions
Where 
and 
And for this case we select a sample size of n= 15. and we want to know the distribution for the sample mean 
. We can assume that the distribution for is approximately normal and given by:
Asuming that the distribution for X is also approximately normal. So then the parameters are:
In this sequence, our common ratio is -3 (each value is -3 times the previous value). The first (or 1th) term of the sequence is 6, so we can form our equation:
Now we have to find the 11 term. To do so, we plug 11 into our equation where the x would be. Once that's done, we do the math as follows:
(plug in)
(simplify by subtracting 1 from 11 to get 10)
(simplify by calculating 3 to the power of 10 to get 59049)
(solve by multiplying 6 by 59040 to get 354294
Therefore, our 11th term in the sequence is 354394.
The answer is 3/2
Find the slope of the line
M = y2-y1/ x2-x1
M=9-0 /6-0
M=9 divide 3 / 6 divide by 3
M= 3/2 cm/s
Answer:
5
Step-by-step explanation:
-2x - y = -3
y = -3x + 2
-2x - (-3x + 2) = -3
-2x + 3x - 2 = -3
x = -1
y = -3*-1 + 2 = 5
The difference is +3.
You move from -6 to -5 to -4 to -3.
That’s 3 units of difference.
