Answer:
Simple random sampling method is used here.
Step-by-step explanation:
Given is that the evening host of a dinner dance reached into a bowl, mixed all the tickets around, and selected the ticket to award the grand door prize.
We can see that this is a simple random sampling method as every name on the ticket has an equal opportunity to get selected.
For this case we have the following equation:

From here, we clear the value of x.
We have then:

Then, we look for the value of 2x. We have then:

Answer:
The value of 2x is given by:

Answer:
<u>The width of the top surface of the desk is 1.4 feet.</u>
Step-by-step explanation:
1. Let's review all the information given for solving this question:
Length of the top surface of a desk = 5.6 feet
Width of the top surface of a desk= x
2. Let's find the width of the top surface of the desk
Length of the top surface of a desk = Four times the width
5.6 = 4x
5.6/4 = 4x/4 (Dividing by 4 at both sides)
1.4 = x
<u>The width of the top surface of the desk is 1.4 feet.</u>
Answer:
Option A.
Step-by-step explanation:
In order to write any polynomial in standard form, we need to check the degree of each term, then write each term in order of degree, from highest to lowest, left to right.
The given polynomial is

Here, the combine degree of x and y in each term is 4.
If we arrange the terms according to the degree of x, then

If we arrange the terms according to the degree of y, then

Hence, the correct option is A.
