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
