Tony works in a factory that produces 1,000 computers each day. When 50 were sampled, it was found that 7 were defective. Estimate how many defective computers are made each day
What is
(7/5)(1000) ?
7/50
7/50 = x/1000.
X = (7/50) * 1000 =

140 is the answer
To estimate how many defective computers are made each day, we can use the concept of proportion.
We are given that Tony's factory produces 1,000 computers each day, and when a sample of 50 computers was taken, 7 were found to be defective.
First, we need to find the proportion of defective computers in the sample. We can do this by dividing the number of defective computers by the total number of computers in the sample:
Proportion of defective computers = (Number of defective computers) / (Total number of computers in the sample)
In this case, the proportion of defective computers is 7/50.
Next, we can use this proportion to estimate the number of defective computers made each day. Since we know that the factory produces 1,000 computers each day, we can set up a proportion to find the estimated number of defective computers:
(Proportion of defective computers) = (Number of defective computers) / (Total number of computers made each day)
Substituting the values we have:
7/50 = x/1000
Cross-multiplying, we get:
7 * 1000 = 50 * x
Simplifying further:
7000 = 50x
Dividing both sides by 50 gives us:
x = 7000 / 50
Therefore, the estimated number of defective computers made each day is 140.
