Answer: There are 6 rows of caravans at the park.
Step-by-step explanation:
To solve this problem, divide the total of 30 caravans by the maximum number of caravans in a row. This will result in the amount of rows at the park.
30 / 5 = 6

Answer:
The approximate standard deviation of the sampling distribution of the mean for all samples of size n is
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.
The mean life expectancy of a certain type of light bulb is 945 hours with a standard deviation of 21 hours
This means that .
What is the approximate standard deviation of the sampling distribution of the mean for all samples of size n?
The approximate standard deviation of the sampling distribution of the mean for all samples of size n is
Answer:
A: 50
Step-by-step explanation:
because its 50$ for setup and 30 each hour for 5 hours. so 30x5=150 +50 = 200÷ nelson and 3 friends =50$ each
