Step-by-step explanation:
÷6
First, simplify the 6
to an improper fraction, which is:

Next rewrite the equation using the improper fraction:
÷
Now, in order to divide the fraction, we will need to flip the second fraction over, and then multiply the two fractions together. A great way to remember this is the phrase <em>Copy Dot Flip - </em>Copy the first fraction, put a dot for multiplication, and flip the second fraction.
·
Finally, multiply together and simplify/reduce if needed:
<u>The final answer is </u>
<u> and no simplification or reduction is needed</u>
Answer:
a) 
b) 
Step-by-step explanation:
Given that:
population mean
= 30,000
sample size n = 800
population proportion p = 0.6
a)
The mean of the the sampling distribution is equal to the population proportion.


b)
The standard deviation of the sampling distribution can be estimated by using the formula:






Answer:
Output = 8- input
Step-by-step explanation:
The first point is (1,7)
The input is 1 and the output is 7
The lines goes down, so we know that this is subtraction
Output = 8- input
7 = 8-1
Lets check another point
(5,3)
3 = 8-5
This checks

Without any more information we can't find the actual numerical representation of the length and width but we can give an expression that will allow us to find them...
We let the width equal x, so the length is 3x. That would be the dimensions...
length = 3x
width = x
So to find perimeter the expression would be
2(3x) + 2(x) =
6x + 2x =
8x
For the area it would be
a= length × width
a = 3x × x
a = 3x^2
