Answer:

350 lightbulbs

Step-by-step explanation:

First find the number of batches made.

20,000 divided by 400 = 50

This means that there are 50 batches in which 7 light bulbs will be selected at random to be inspected.

We can multiply the number of batches to the lightbulbs being inspected.

50 times 7 = 350

Therefore, 350 lightbulbs will be inspected.

Please tell me if I am incorrect :)

What is the slope of the line that goes through (0,0) (5,1)
GalinKa [24]
Hey there!

In order to solve this problem, we can use the slope given two points formula:

y2-y1/x2-x1

Now, we can plug in our points to get:

1-0/5-0 = 1/5

Your answer is 1/5, or B.

Hope this helps!
