Answer:

C

Step-by-step explanation:

Hey There!

So the answer is C because essentially answer choice c is saying that you can predict what the amount of problems that the next kid would complete in 30 minutes because all of the samples have a mean of 15.6-15.9 or that all of the samples are reliable because all of the means are near each other

And if you didnt know the mean is the average of all of the numbers in the sample

There C is your answer

What is 0.5 divided by 12.5
lisabon 2012 [21]

Answer:

<em>0</em><em>.</em><em>04</em><em> </em><em>o</em><em>r</em><em> </em><em>4</em><em>%</em>

Step-by-step explanation:

<em>-A fraction consists of two numbers and a fraction bar: 0.5/12.5</em>

<em>- The number above the bar is the numerator: 0.5</em>

<em>The number below the bar is the denominator: 12.5</em>

<em>-Divide the numerator by the denominator to get fraction's value: Val = 0.5 ÷ 12.5</em>

<em>Calculate fraction's value.</em>

<em>Divide the numerator by the denominator to get fraction's value:</em><em> </em>

<em>0.5 ÷ 12.5 </em>

<em>=</em><em> </em><em>0.04</em>

<h3><em> </em><em>Calculate the percent value:</em></h3>

<em>Note:100/100 = 100 ÷ 100 = 100% = 1Multiply a number by the fraction 100/100,... and its value doesn't change.0.04 =</em>

<em>=</em><em> </em><em>0.04 × 100/100 </em>

<em>=</em><em> </em><em>(0.04 × 100)/100 </em>

<em>=</em><em> </em><em>4/100 </em>

<em>=</em><em> </em><em>4%;</em>

<h3><em>In other words:</em></h3>

<em>1) Calculate fraction's value.</em>

<em>2) Multiply that number by 100.</em>

<em>3) Add the percent sign % to it.</em>

<em>Answer:</em>

<em>0.5</em><em>÷</em><em>1</em><em>2.5 = 4%</em>
