Answer:

The expected number of nondefective lightbulbs is 980 out of a random sample of 1,000 bulbs.

Explanation:

Hi, if the company is right, this is the operation that we need to do.

Bulbs(operating)=1,000*0.98=980

So, we are expecting 980 working bulbs out of a sample of 1,000

Best of luck

kramer

The statement that when selecting words to include in a résumé, they should be complex in nature is false. In contrast, when writing a resume you should use concise, simple, strict and clear sentences. The resume presents a person's  backgrounds and skills and the wording should be very carefully selected.

Tema [17]

Answer:

Since net revenue has increased from $140 million to $246 million = $106 million by considering all costs thus all the costs and revenue shall be considered.

Explanation:

For calculating the present value, all the cost and revenue will be considered.

Original revenue = Sale of 10 million chips

10 million \times $20 = $200 million

Less: Cost = 10 million \times $6 = $60 million

Net Revenue = $140 million

In case of introducing new chips

Revenue will be as follows

12 million \times $25 + 3 million \times $20

= $300 million + $60 million = $360 million

Less: Costs 12 million \times $8 + 3 million \times $6

= $96 million + $18 million = $114 million

Net Revenue = $360 - 114 = $246 million

Since net revenue has increased from $140 million to $246 million = $106 million by considering all costs thus all the costs and revenue shall be considered.
