First you need to get all variables on one side. You do that by multiplying the reciprocal of the fraction to everything.
N(5/1) x 1/5(5/1)=2/15(5/1)
5n=2/15 x 5/1
Then solve the multiplication problem
5n= 10/15
Then you should reduce the fraction
5n=2/3
Then divide both sides by 5
5n/5=N
2/3 divided by 5 =2/15
N=2/15
Answer:
20.27
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation 
Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?
This is s when
. So

So the correct answer is:
20.27
Hey!
To simplify the equation provided we must first start off by grouping like terms.
<em>Original Equation :</em>
10 + 3c + 5d - 7c + d
<em>New Equation {Grouped Like Terms} :</em>
3c - 7c + 5d + d + 10
Now we add similar elements.
<em>Old Equation :</em>
3c - 7c + 5d + d + 10
<em>New Equation {Added Similar Elements} :</em>
-4c + 5d + d + 10
Next we add the other similtar elements.
<em>Old Equation :</em>
-4c + 5d + d + 10
<em>New Equation {Add Similar Elements} :</em>
-4c + 6d + 10
<em>So, this means that the equation 10 + 3c + 5d - 7c + d simplified is</em> -4c + 6d + 10.
Hope this helps!
