Given:
Area of the square = 81 square units.
Let's find the perimeter.
To find the perimeter of a square, apply the formula:
Perimeter = 4L
Where L is the side length of one side of the square.
To find L given the area, apply the formula:
Hence, we have:
Take the square root of both sides:
![\begin{gathered} \sqrt[]{81}=\sqrt[]{L^2} \\ \\ 9=L \\ \\ L=9\text{ units} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Csqrt%5B%5D%7B81%7D%3D%5Csqrt%5B%5D%7BL%5E2%7D%20%5C%5C%20%20%5C%5C%209%3DL%20%5C%5C%20%20%5C%5C%20L%3D9%5Ctext%7B%20units%7D%20%5Cend%7Bgathered%7D)
The length of one side of the square is 9 units.
To find the perimeter, substitute 9 for L in the formula for Perimeter of a square.
Perimeter = 4L = 4(9) = 36 units
Therefore, the perimeter of the square is 36 units.
ANSWER:
36 units.
The answer would be 23 on the third term
Answer:
Domain: 6,10,8,20
Step-by-step explanation:
Domain is basicly the x-value.
Using the <u>normal distribution and the central limit theorem</u>, it is found that there is a 0.0409 = 4.09% probability that, from a simple random sample of 300 adults in the county, less than 50% would say they believe that gardening should be part of the school curriculum.
In a normal distribution with mean 
and standard deviation 
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample proportions for a proportion p in a sample of size n has
In this problem:
- The proportion is of 55%, hence
- The sample has 300 adults, hence
Then, the <u>mean and the standard error</u> are given by:
The probability is the <u>p-value of Z when X = 0.5,</u> hence:
By the Central Limit Theorem
has a p-value of 0.0409.
0.0409 = 4.09% probability that, from a simple random sample of 300 adults in the county, less than 50% would say they believe that gardening should be part of the school curriculum.
