Let length, width, and height be s.
Then diagonal of any face would be √( s² + s² ) = √( 2s² )
And we know that it measures √( 500 ) so that's sufficient for us to figure out the length of an edge of the cube. We do not need to worry about the diagonal of the cube.
Now we have to solve √( 500 ) = √( 2s² )
Square both sides:
500 = 2s²
Divide both sides by 2:
250 = s²
Take the square root of both sides:
√(250) = s ≈ 15.8113883
Rounding to nearest tenth:
s ≈ 15.8
Final answer: 15.8
Hope this helps.
90 - 40 = 50
Complementary angles add up to 90 degrees.
If one angle is 40 degrees less than the other, you just put it into an equation where 40 is subtracted from 90.
The answer would then be 50 degrees.
Answer: c. 72% is a statistic and 56% is a parameter.
Step-by-step explanation:
- A population is a large group of all possible observations required for a study by the researcher's point of view.
- A Sample is a finite subset of population that is used by researcher to represent the entire population in an analysis.
- A parameter is a number that measure a characteristic for the entire population.
- A statistic is a number that measure a characteristic for the sample.
- A statistics given an estimate to the population parameter.
Given : A study of voting chose 663 registered voters at random shortly after an election.
Population of interest : "registered voters"
Sample : " 663 registered voters "
72% of 663 registered voters said they had voted in the election.
⇒ Statistic = sample proportion registered voters voted in the election.= 72%
Election records show that only 56% of registered voters voted in the election.
⇒ Parameter = Population proportion of registered voters voted in the election = 56%
Hence, the correct answer is "c. 72% is a statistic and 56% is a parameter."

hello its me again and im trying to help you kid
Step-by-step explanation:
The answer to ur question is b
X=10, AE is 46 because its twice the size of BF, set 5x-4 equal to 46 (5x-4=46) and solve
