Answer:
<em>B)</em><em> 8.9 lbs
</em>
<em>C)</em><em> 9.5 lbs
</em>
<em>D)</em><em> 9.8 lbs
</em>
<em>E)</em><em> 10.4 lbs</em>
Step-by-step explanation:
From the graph, 9.5 is the mean of the sample and 0.5 is the standard deviation of the sample.
As we have to find the weights that lie within the 2 standard deviations of the mean i.e
![=9.5\pm 2(0.5)](https://tex.z-dn.net/?f=%3D9.5%5Cpm%202%280.5%29)
![=8.5,10.5](https://tex.z-dn.net/?f=%3D8.5%2C10.5)
Among the given weights only 8.9 lbs, 9.5 lbs, 9.8 lbs, 10.4 lbs will lie within 2 standard deviations of the mean.

Answer:
<h2>9/28</h2>
Step-by-step explanation:
<em><u>2 3/7 - 1 1/4</u></em>
<em><u>2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:</u></em>
<em><u>2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4</u></em>
<em><u>2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4Next find the Lowest Common Denominator:</u></em>
<em><u>L.C.D = 28</u></em>
<em><u>L.C.D = 2821 - 12/28</u></em>
<em><u>L.C.D = 2821 - 12/28= 9/28</u></em>
<u>It won't be a mixed number because the denominator is bigger than the numerator.</u>
A because the graph of a direct proportion crosses the origin.
