Answer:
100
Step-by-step explanation:
Total produced= 5000 bulbs
Defective bulbs= 5 out of every 250 bulbs produced
If 5 out of 250 produced bulb is defective
Then,
Good bulbs= 250-5
=245
If the company produces 5,000 bulbs, how many will be defective?
Total defective bulbs out of 5000 bulbs produced=
Total production/250×5
=5000/250×5
=20×5
=100 bulbs
That is, defective out of 5,000 produced is 100 bulbs
Answer:
There is an expected 100 defective lightbulbs
Step-by-step explanation:
In this question, we are asked to calculate the number of light bulbs we think will be defective given that there are usually 5 out of 250 defectives in a batch.
Now, to adequately account for the number of defective lightbulbs, let’s calculate the proportion of lightbulbs which are defective. From the question, this is a case of 5 out of 250. Hence, the ratio of defective lightbulbs mathematically is 5/250
Now we have a batch of 5,000 produced, to know the total number of defectives expected, we simply multiply the ratio of defectives per batch by the total produced.
Mathematically, this will be;
5/250 * 5,000 = 100
