Question

A factory inspector found 3 defective microchips out of a total of 750

microchips made. Which proportion can be used to predict the number of
defects, x, in a batch of 10,000 microchips?

Answer 1

Option B

Explanation:

Proportion of number of defective pieces to the number of microchips in a batch can be represented by the ratio =
`\frac{\text{Number of microchips not in good condition}}{\text{Total numbers of microchips}}`

If 3 microchips are defective in a batch of 750 microchips,

Proportion =
`(3)/(750)`

If 'x' chips are defective in a batch of 10000 microchips,

Proportion =
`(x)/(10000)`

If both the proportions are equal,

`(3)/(750)=(x)/(10000)`

Therefore, Option B will be the answer.
