Answer:
It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.
Step-by-step explanation:
Given that:
sample size n = 1600
sample mean
= 20000
standard deviation = 5000
The objective is to choose from the given option about what most closely resembles the relevant box model.
The correct answer is:
It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.
However, if draws are made without replacement, the best estimate of the average amount for the bride will be $20,000
Similarly, the standard error for the sample mean = 


the standard error for the sample mean = 125
Triangles with a 90 degree angle. We use the sine, cosine and tangent functions to determine the missing angles and sides.
First of all, let's take a look on the question.

Here, 0 is added to 15 and the resultant is 15 only. So, we can say that 0 when added with any number gives the same number as the resultant.
So, the property is known as <u>Identi</u><u>ty</u> property because 0 is added to get the identity of the same number.
<u>The Correct Option:</u>

So, let's know more...
- Commutative property ➝ a + b = b + a
- Associative property ➝ a + (b + c) = (a + b) + c
- Distributive property ➝ a(b + c) = ab + ac
So this is the general form of these properties which is general observed in the rational numbers.

A= 1/2(7 + 11)(5)
A = 1/2(18)(5)
A = 45 square units
