solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation. You'll probably start out by just solving proportions, like this:

<span><span><span>Find the unknown value in the proportion:  </span><span>2 : x = 3 : 9.</span></span><span>2<span> :</span> x = 3<span> :</span> 9</span>First, I convert the colon-based odds-notation ratios to fractional form:.Then I solve the proportion:<span> 
</span><span>9(2) = </span><span>x(3)</span> <span>
1</span><span>8 = 3x</span><span> 
</span><span>6 = x</span></span><span><span><span>Find the unknown value in the proportion:  </span><span>(2x + 1) : 2 = (x + 2) : 5</span></span><span>(2x + 1)<span> :</span> 2 = (x + 2)<span> :</span> 5</span><span><span> ADVERTISEMENT</span><span> </span></span>First, I convert the colon-based odds-notation ratios to fractional form:Then I solve the proportion:<span> 
</span><span>5(2x + 1)  =  2(x + 2)</span><span> 
</span><span>10x + 5  =  2x + 4</span><span> 
</span><span>8x  =  –1</span><span> 
</span><span>x = –1/<span>8</span></span></span>

Answer:

B). Graph B

Step-by-step explanation:

A Histogram is a graphic representation of data using bars varying in height as per the range of values.

In the given question, the second option correctly represents the data provided in the table using a histogram. It portrays the class ranging from 0.320 - 0.329 with an average of 1 in the first bar, from 0.330 - 0.339 with an average of 14 runs in the second bar, and moves so on till 0.360-0.369 correctly. The other options fail to portray the numerical distribution appropriately and hence, <u>option B</u> is the correct answer.
