Otrada [13]

Answer:

Option B

Step-by-step explanation:

Given that a  candy manufacturer is interested in the distribution of colors in each of its packages of candy sold. The manufacturer randomly sample packages from multiple batches at one factory.

Because he resorts to only one factory, there may be bias in the sample.  Other factories may have different processes of the settings and also if a diversified sample is taken then it is likely to represent the whole population, and hence results would be more accurate

Option A is incorrect since only one factory was done

C and D are not selected because one factory result cannot be generalised to all other factors in the same country or outside.

So answer would be

B) No, because the other factories may have different processes or the settings

G^2+3g=18 solve for g
amid [387]

<em>g = 0 </em>

<em>Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation.</em>

<em>g^2+3*g-(18*f*o*r*g)=0  </em>

<em> </em>


<em> </em>

<em>   g2 - 18gfor + 3g  =   g • (g - 18for + 3)  </em>

<em> </em>


<em>  g • (g - 18for + 3)  = 0  </em>

<em>  A product of several terms equals zero.  </em>

<em>When a product of two or more terms equals zero, then at least one of the terms must be zero.  </em>

<em> We shall now solve each term = 0 separately.  </em>

<em> In other words, we are going to solve as many equations as there are terms in the product .</em>

<em> Any solution of term = 0 solves product = 0 as well. </em>

<em> </em>

<em>Solving a Single Variable Equation : </em>

<em> 3.2      Solve  :    g = 0  </em>

<em> </em>

<em>  Solution is  g = 0  </em>

<em> </em>

<em> </em>


<em> g-18for+3  = 0  </em>

<em> </em>

<em>In this type of equation, having more than one variable, you have to specify for which variable you want the equation solved. </em>
