Acompany has 500 computers that are used by its employees. a sample of 40 of these computers finds that 12 of them require an update to the printer driver. what is the best estimate of the percent of the company's computers that require an update to the printer driver?

30 percent

Step-by-step explanation:

12 computers require update in every 40 computers

This means

40=12

500=?

=(500×12)÷ 40 =150 computers

percentage= (150/500)× 100

30 percent

For this case we have that of a sample of 40 computers, 12 of them require updating, this is:

40 > 100%

12 > x

Where the variable "x" represents the percentage of the sample that requires updating.

Then, of the sample obtained, 30% of computers require an update.

If you want to obtain the number of "y" computers that require updating, knowing that 30% requires it and you have 500 computers, we solve the following expression:

500 > 100%

y > 30%

30%

45
