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

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
