The average starting salary for graduates at a university is $33,000 with a standard deviation of $2,000. If a histogram of the
data shows that it takes on a mound shape, the empirical rule says that approximately 95% of the graduates would have a starting salary between _______.
1 answer:
Answer:
Approximately $37000
Explanation:
A standard normal curve will be used to solve this question since the histogram of the data takes on a mound shape.
The mean salary is $33000 with one standard deviation equalling $2000.
Using the normal curve, 95% of the salary will lie between 2 standard deviation. i.e. $33000+$2000+$2000=$37000

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 $20 = $200 million
Less: Cost = 10 million $6 = $60 million
Net Revenue = $140 million
In case of introducing new chips
Revenue will be as follows
12 million $25 + 3 million
$20
= $300 million + $60 million = $360 million
Less: Costs 12 million $8 + 3 million
$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.
