Answer:
[B]
Step-by-step explanation:
<em>Given:</em>
<em>People leaving the library were asked how many books they checked out that day The result are: 1,2, 3, 5, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20</em>
<em>To Find:</em>
<em>Which histogram correctly shows the data set?</em>
<em>Solution:
Since it given from the histogram:</em>
<em>0-5, 6-11, 12 - 17,18-23</em>
<em>From the result :</em>
<em>1,2, 3, 5, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20</em>
<em>Thus,</em>
<em>1,2,3,5 = 0-5</em>
<em>8,9,10,11 = 6-11</em>
<em>12,13,14,15,16 = 12-17</em>
<em>18,20 = 18-23</em>
<em>From this we can see that:</em>
<em>for </em>
<em>0 - 5 = 4</em>
<em>6 - 11 = 4</em>
<em>12 - 17 = 5</em>
<em>18 - 23 = 2</em>
<em>Hence, the answer is [B]</em>

Answer:
Option B
Step-by-step explanation:
We are given the following system of equations -
Now by Cramer's Rule, we would first write down the matrix of the coefficients , replacing each column with the answer column -
,
Replace each column of the coefficients shown at the top, with the answer column at the bottom respectively -
Now solve through Cramer's Rule -
x = Dx / D = - 6,
y = Dy / D = - 1,
z = Dz / D = 1
<u><em>Solution = ( - 6, - 1, 1 ) = Option B</em></u>
