Answer:
By the Central Limit Theorem, the distribution of the sample means is approximately normal with mean 41 and standard deviation 2.92, in thousands of dollars.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes 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.
Mean of 41, standard deviation of 28:
This means that 
Sample of 92:
This means that 
Distribution of the sample means:
By the Central Limit Theorem, the distribution of the sample means is approximately normal with mean 41 and standard deviation 2.92, in thousands of dollars.
M=4a+2c
a=10
c=5
m=4*10+2*5=40+10=50
Answer: 50
Answer:
see explanation below
Step-by-step explanation:
In order to do this, you can put and solve this in this way:
we know that the ratio between chips and water is 4:3 so:
Chips/Water = 4/3
Solving for chips:
Chips = 4 Water / 3
Now put the price of the water here, and you should get the price of the chips:
Chips = 4 * 1.8 / 3
Chips = 2.4 $
b) If the chips cost 2.4 and the drink 1.8, the total is 4.2, therefore, the total amount is:
4.2/6 = 2.1/3 = 0.7/1
c) If 6$ is 37.5% then the 100% would be:
6 * 100 / 37.5 = 16$
Answer:
The answer is A.
