To find this answer, we must first find the percentage of batteries that are defective. We can do this by dividing 3 by 500.
3 / 500 = 0.006
So our percentage of defective batteries is 0.6%.
Now, to find out how many defective batteries would be in a batch of 12000, we just need to multiply the constant (percentage of defective batteries) by the amount in the new batch.
12000 * 0.006 = 72
In a shipment of 12,000 batteries, 72 will be defective, so the correct answer choice would be B.
Hope that helped =)

Answer:
She has 60% of money left.
Step-by-step explanation:
You have to find out how much Php that Lei has left :
Php 150 - Php 48 - Php 12 = Php 90
She has a remaining of Php 90. Next, you have to find the percentage by dividing hy original amount and then, multiply by 100 :
(90/150)×100 = (3/5)×100 = 60%
Use these equations when converting polar equations to parametric equations:


We know that
, so substitute that into both equations for x and y.


Now, replace
with any variable that you want to represent the parametric equations in. I'll use the standard variable, 


Thus,
represented in parametric form is:

Let me know if you need any clarifications, thanks!
