Step-by-step explanation:
Two inequalities. A graph is shown.
Answer:
The mean is 0.54 and the standard deviation is 0.05.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a sample proportion p in a sample of size n, the mean of the sampling distribution is p and the standard deviation is .
In this problem:
So
Mean 0.54
Standard deviation .
The mean is 0.54 and the standard deviation is 0.05.
Answer:
-12
Step-by-step explanation:
Since m1 = 10x + 4 and m2 = 5x - 4 then we can write it as:
10x+4=5x-4
Combine the like terms:
10x-5x=-4-4
5x=-8
Divide both sides by 5
5x= -8/5
x=-8/5
Now substitute the value of x in 5x-4
= 5(-8/5) - 4
= -8-4
= -12
Thus m2 = -12....
