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?

Option B

Step-by-step explanation:

Proportion of number of defective pieces to the number of microchips in a batch can be represented by the ratio =

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

Proportion =

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

Proportion =

If both the proportions are equal,

Therefore, Option B will be the answer.

i can

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
