A company manufactures batteries in batches of 6 and there is a 3% rate of defects. Find the mean number of defects per batch.

the mean no of defects per batch is 0.18

Step-by-step explanation:

The computation of the mean no of defects per batch is shown below:

= Number of batches × percentage rate of defects

= 6 × 3%

= 0.18

Hence, the mean no of defects per batch is 0.18

We simply applied the above formula so that the per batch defects of the mean no would come

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
