Alex17521 [72]

Answer: 300

Step-by-step explanation:

Given , An electronics retailer receives a shipment of 6,000CDs to distribute to its stores.

i.e, Total CD's he has now = 6,000

Also, a quality control manager inspects a random sample(S) of 40CD's , the number of defective(D) CD's are 2.

Then , the proportion of defective( D) CD's = $\dfrac{D}{S}=\dfrac{2}{40}=0.05$

Now , the number of CDs in the shipment are likely to be defective = ( Total CD's) x (proportion of defective CD's)

= 6000 x 0.05

=300

Hence, the number of CDs in the shipment are likely to be defective =300

Instructions: If varies inversely as and =2 when =8, find when =2. Write the equation using the given information, then use the

grigory [225]

Solution:

Given that;

varies inversely as

$\begin{gathered} y\propto x \\ The\text{ expression ecomes the equation below} \\ y=kx \\ Where\text{ k is the constant} \end{gathered}$

=2 when =8,

$\begin{gathered} y=kx \\ 2=k(8) \\ k=\frac{2}{8}=\frac{1}{4} \\ k=\frac{1}{4} \end{gathered}$

The equation becomes

$\begin{gathered} y=kx \\ y=\frac{1}{4}x \end{gathered}$

The value of when =2

$\begin{gathered} y=\frac{1}{4}x \\ y=\frac{1}{4}(2)=\frac{2}{4}=\frac{1}{2} \\ y=\frac{1}{2} \end{gathered}$

Hence, y = 1/2
