Explanation:
The sample mean is not always equal to the population mean but if we take more and more number of samples from the population then the mean of the sample would become equal to the population mean.
The Central Limit Theorem states that we can have a normal distribution of sample means even if the original population doesn't follow normal distribution, But we have to take a lot of samples.
Suppose a population doesn't follow normal distribution and is very skewed then we can still have sampling distribution that is completely normal if we take a lot of samples.
Answer:
16,000,000
Step-by-step explanation:
to start off your going to need to use PEMDAS (parenthesis exponents multiplication division addition subtraction)
so we are going to start IN the parenthesis the next step is doing the exponents so its going to look like this 1,000,000
rewrite the problem: 4(4×1,000,000)
use the next step in PEMDAS multiplication rewrite the problem:
4(4,000,000)
multiply: 16,000,000
Hi,
Now just divide both sides of equation by -4.
Simplify:
Decimal form:
Hope this helps.

Answer:
14.25 units
Step-by-step explanation:
Area of a square=
Solving the equation using quadratic equation then as attached
x=14.25 units
To prove
x-3=14.25-3= 11.25 units
area=11.25*11.25=126.5625 sq units
