Answer:
its either 18.92
or 25.58%
but I believe it is 18.92 I may be wrong though
Answer:
18 pi sqrt(2)
Step-by-step explanation:
We know the sides of a Pythagorean triangle
a^2 + a^2 = c^2
18^2 + 18^2 =c^2
2 * 18^2 = c^2
Taking the square root of each side
c = 18 sqrt(2)
This is the diameter of the circle
We want to find the circumference
C = pi * d where d is the diameter
C =pi* 18 sqrt(2)
First change the mixed fraction to improper fraction, and then find common denominators.
5 1/2 = 11/2
4/9(2/2) = 8/18
11/2(9/9) = 99/18
-------------------------------------------------------------------------------------------------------------------
Next, subtract
99/18 - 8/18 = 91/18
91/18 = 5.05
-------------------------------------------------------------------------------------------------------------------
As you are finding the best estimate, 5.05 is closest to 5, which makes your answer D)

Step-by-step explanation:
2/3 as a percent is .6666666666667
Answer:
7+8+6+5+4 = 30
30+1=31
31/2 = 15.5
Answer = 60-70
Step-by-step explanation:
Put the results in numerical order (in a frequency table this will already be done)
Count the total amount of results and add one
Divide this by 2 to find the position of the middle result
Find the middle result in the numerically ordered list or frequency table
You will then have the median of the set of results
