Answer:
n = 3
Step-by-step explanation:
It is given that W is between X and Y. It means,
WX = WY
or
XY = WX+WY
We have, WX=6n-10, XY=17, and WY=3n
So,
17= 6n-10+3n
Adding both sides 10
17+10= 6n-10+3n+10
27=9n
n = 3
Hence, the value of n is 3.
Answer:
<h3>20</h3>
Step-by-step explanation:
Standard deviation of the mean is expressed as:
SM = s/√n
s is the standard deviation of all invoices
n is the sample size of the invoiced
Given
s = $200
n = 100
Required
Standard deviation of the mean
Substitute the given parameters into the given equation
SM = 200/√100
SM = 200/10
SM = 20
Hence the standard deviation of xbar is 20
Answer:

Answer:
3/5
Step-by-step explanation:
Set it equal to 0
5x-3=0
Then solve for x
5x=3
x=3/5
Check
5(3/5) - 3
3-3
0
First split your model into 10 equal sections then you shade/color in 6 of them.
There it goes that is 6/10 bench mark!
