Answer:
The bridge 's owner has a natural monopoly, and the marginal production cost (letting another car drive through it) is close to nil.
Explanation:
Since building several bridges to compete is inefficient, but building one bridge at a lower average cost to customers would be effective. If the private monopolist builds the bridge it can charge customers exceptionally high prices.
There is a high fixed cost involved with constructing a bridge. Hence constructing a bridge is a mere privilege. Furthermore, there is no extra cost to allow another car to cross the bridge. It means that the marginal cost is zero or closer.
Answer:
(a). For every additional square foot of area of a house, the price is predicted to increase by $61
(b) The asking price is $145410 and the residual is a negative $4100
Explanation:
As per the data given in the question,
a) From regression equation Slope = 0.061
So slope = (0.061 × 1,000) ÷ 1 sq. ft.
= $61 per sq. ft.
For every additional square foot area price is increased by $61
b) If size of the house is = 1600 square foot then
Price = 47.81 + 1600*0.061
=$145,410
The asked price is $4,100 less than estimated price and residual is not positive
Hence,
Asking price = $145,410
Residual price = a negative $4,100
<u>Solution and Explanation:</u>
a) 51% of users of mobile phones use their phone at least once per hour,
It is a binomial distribution with n = 150, p = 0.51
mean = np = 150 multiply with 0.51 = 76.5
SD= sqrt(np(1-p) )= 6.1225
Since np and n(1-p) > 5, we can assume the distribution is normal.
B) please see the attached file.
c) It is a binomial distribution with n = 150, p = 0.02
mean = np = 150*0.02 = 3
SD= sqrt(np(1-p) )= 1.71464
Since np < 5, we cannot assume the distribution is normal.
Answer:
Option d. Fixed period
Explanation:
time is very essential. Anytime the policy owner specifies payment to be guaranteed for a specific period regardless of who is the beneficiary, policy owner or who receive the payment,is the fixed period settlement option.
Anything that occur to annuity after the owner's death is dependent on the type of annuity and its payout plan.
A fixed-period, is that which is for a certain period of time. the annuity guarantees payments to the annuitant for a set length of time. example is about 10, 15, or 20 years and case payments will continue to be paid to the beneficiary until the time given or period is due or when account’s balance reaches zero.
