Tony works in a factory that produces 1,000 computers each day. When 50 computers were sampled, it was found that 7 were defective. Estimate how many defective computers are made each day. (1 point)
140 computers
7 computers
169 computers
265 computers
Using proportion:
7/50 = x/1000
Cross-multiply:
50x = 7000
Divide both sides by 50:
x = 140
Therefore, the estimate for how many defective computers are made each day is 140 computers.
The answer is: 140 computers.
To estimate the number of defective computers made each day, we can set up a proportion using the sample data.
First, calculate the proportion of defective computers in the sample:
Proportion of defective computers = (Number of defective computers in the sample) / (Total number of computers in the sample)
Proportion of defective computers = 7 / 50
Proportion of defective computers = 0.14
Next, use this proportion to estimate the number of defective computers made each day:
Estimated number of defective computers = (Proportion of defective computers) * (Total number of computers made each day)
Estimated number of defective computers = 0.14 * 1,000
The estimated number of defective computers made each day is 140 computers.
Therefore, the answer is: 140 computers.
