Answer:
0
Step-by-step explanation:
<u>Step 1: Make common denominators</u>
What is the LCM of 21 and 7: 7
So, we need to convert both fractions into a 21 denominator.
<em>15/21 * 1/1 = 15/21</em>
<em>5/7 * 3/3 = 15/21</em>
<em />
<u>Step 2: Subtract the numbers</u>
15/21 - 5/7 is same as 15/21 - 15/21
15/21 - 15/21
<em>0</em>

Answer: 0
Answer: 40000
Step-by-step explanation:
The formula to find the sample size is given by :-
, where p is the prior estimate of the population proportion.
Here we can see that the sample size is inversely proportion withe square of margin of error.
i.e. 
By the equation inverse variation, we have
Given : 
Then, we have
Hence, the sample size will now have to be 4000.
We're not supposed to help with exams. This isn't an exam, is it?
A(0)=202, A(37)=half that.
Last choice.
Answer:
The answer to your question is Triangle's area = 520 in², Square's area = 576 in²
Step-by-step explanation:
Process
1.- Calculate the area of the triangle
-Find the length of the base using the Pythagorean theorem
c² = a² + b²
-Solve for b²
b² = c² - a²
-Substitution
b² = 37² - 35²
-Simplification
b² = 1369 - 1225
b² = 144
b = 12 in
-Find the base
base = 2(12) = 24 in
-Find the area of the triangle
Area = base x height / 2
-Substitution
Area = 24 x 35 / 2
-Simplification
Area = 420 in²
2.- Find the area of the square
Area = side x side
-Substitution
Area = 24 x 24
-Result
Area = 576 in²
