Answer:
10cm
Step-by-step explanation:
First let's define variables a and x:
a = area of rectangle and square
x = side of square
Now let's create an equation to calculate a using the square and an equation to calculate a using the rectangle:
Using square: 
Using rectangle: 
Now we want to solve for x so let's combine the equations since they are both equivalent to a

Simplify

Solving this we get 10 and -3
Since it is impossible for a square to have a negative side value we can conclude that the value is 10cm
This can then be checked by plugging in 10 as x in our equations and seeing if we get the same a value:
Using square: 
Using rectangle: 
1,2,4,8,16
Them are the answers for the factors
Using it's concept, it is found that the sample proportion for this population is of 0.4.
- The estimate of the <em>sample proportion for a population</em> is given by the <u>number of desired outcomes divided by the size of the sample</u>.
In this problem:
- 1,599 of those surveyed responded in favor of the park.
- The sample size is of 4,000.
Hence:

The sample proportion for this population is of 0.4.
