Right Triangles and the Pythagorean Theorem
The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
The side opposite the right angle is called the hypotenuse (side c in the figure).
The area of the panel is 80ft^2
Based on the sample results of the population the percentage of population that prefers reading a hard copy i fht e digital copy is 4, the hard copy is 21 and n equas 25 is 84%
Step-by-step explanation:
From the above question we know that .
<u>Total number of population, n = 25</u>
Number of people who prefer to read a digital copy = 4
Number of people who prefer to read a hard copy = 21
As per the question we need to find out the percentage of population who prefer to read hard copy.
So we use the formula
<u>Percent of population preferring hard copy = Hard copy/Total*100</u>
<u></u>
Percent of population that prefers hard copy = 21/25*100
Percent of population that prefers hard copy = 0.84 × 100 = 84%
<u>So , the percent of population who prefers to read a hard copy are about 84%.</u>

The best thing to do is either to find a common denominator or convert them to decimals.
I will find a common denominator.
A common denominator of 3 and 5 is 15.
You multiply the first fraction by 5
2*5= 10
This then becomes 10/15
You then multiply the second by 3.
4*3= 12
Therefore, this becomes 12/15
As the second of these fractions is larger, this means that 4/5 is larger.
The alternative method is to put them into decimals, in which case 2/3= 0.66 and 4/5= 0.8
Hope this helps :)
25.3%
you have to do 4.06-3.24
then do that number divided by the original number then times by 100
