A light bulb manufacturer found that 3 out of every 268 light bulbs in every batch were bad. If they produced 22,158 light bulbs, how many are bad?(1 point)
82 light bulbs are bad.
To find the number of bad light bulbs in a batch of 268, you can divide the total number of light bulbs by the proportion:
268 / 3 = 89.33
Since you can't have a fraction of a light bulb, round this number down to 89.
Then, to find the number of bad light bulbs in 22,158 light bulbs, divide the total number of light bulbs by the number of light bulbs in a batch:
22,158 / 268 = 82.67
Again, round down to get the final answer of 82 bad light bulbs.
Wrong
Apologies for the mistake in my calculation.
To determine the number of bad light bulbs in a batch of 268, you need to calculate the proportion of bad light bulbs in the batch:
3 bad light bulbs out of 268 total light bulbs.
So, the proportion of bad light bulbs in a batch is:
3 / 268 = 0.011194
To find the number of bad light bulbs in a production of 22,158 light bulbs, you need to multiply the total number of light bulbs by the proportion of bad light bulbs in a batch:
22,158 x 0.011194 ≈ 248
Therefore, approximately 248 light bulbs are bad out of 22,158 produced.
