Answer:
10,000 * (square miles in the city)
Step-by-step explanation:
You've been given a population of people for every square mile (10,000) and you're trying to figure out how many people live in the city.
To convert people per a square mile into people, you'll need to know how many square miles you have. I assume you've been given this as the size of the city or how many square miles the city takes up. Just multiply the amount of people per a square mile by the amount of square miles in the city, and it'll give you the population of people in every square mile of the city (the population).
Note:
This is people per a square mile, or in other words, for every square mile of city, 10,000 people live there. If you have 2 square miles of city, then 2 * 10,000 = 20,000 people live there.
Answer:
The sampling distribution of the sample proportion of adults who have credit card debts of more than $2000 will be normally distributed with mean = 0.38 and standard deviation of 0.034.
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 proportion p, the sampling distribution will be normally distributed with mean 
and standard deviation 
In this problem, we have that:
So
The sampling distribution of the sample proportion of adults who have credit card debts of more than $2000 will be normally distributed with mean = 0.38 and standard deviation of 0.034.
As this is a relatively complex division, it is worth doing this on the calculator.
2/346= 0.00578034682
Rounded to 4 decimal places, this is 0.0058
Hope this helps :)
There are 2 14 year olds. The answer is (A).
**
The average should be 12. 11 is one less than 12. You have four 11 year olds. You get a deficit of 1 with each 11 year old, so with four of them the deficit is 4. To compensate for this and being the average to 12, you need to make a surplus of 4. If you add one 14 year old, you make a surplus of 2 (because 14 is 2 more than 12). If you add another 14 year old, you now have a surplus of 4 and that balances it out.

if it's hard to understand tell me and I'll explain it in the simpler way
