C.113
D.3,375

Answer 1

Answer:

33.75

Step-by-step explanation:

Given that the manufacturer produces an average of 450 televisions each day and 0.25% of the numbers produced each day are defective.

Therefore

0.25% of 450 will give the number of defective televisions produced per day

So

0.25% /100 x 450

0.0025 x 450

1.125

This means that 1.125 of televisions produced each day are defective.

Now to get the estimate of defective televisions in 30 days , multiply the number of defective televisions per day by 30 days seeing that the producer produces an average of 450 each day

So

1.125 x 30

33.75

33.75 televisions are defective in 30 days
