Receiver operating characteristic (ROC) graphs are used for selecting the most appropriate classification models based on their performance with respect to the false positive rate (FPR) and true positive rate (TPR).
Give a brief about the Receiver operating characteristic (ROC)?
A receiver operating characteristic curve, often known as a ROC curve, is a graphical figure that shows how a binary classifier system's diagnostic capacity changes when the discrimination threshold is altered. The technique's name comes from the fact that it was initially created for users of military radar sensors beginning in 1941.
Plotting the true positive rate (TPR) against the false positive rate (FPR) at various threshold levels yields the ROC curve. Other names for the true-positive rate include sensitivity, recall, and likelihood of detection. [10] The chance of a false alarm, which is another name for the false-positive rate, may be computed as (1 specificity).

A city is considering a plan to ease traffic congestion by offering to eliminate tolls on cars with 3 or more passengers in them. An
economic analysis is done on the plan. Which conclusion, if reached in this analysis, would weigh against adopting the plan?
A)
Reduced toll revenues would threaten public road maintenance budgets.
B)
Peak traffic times would be spread out over a larger portion of the day,
Typical travel speeds on the toll roads would increase 5% during rush
hours
D)
Average numbers of miles commuting would remain level, due to indirect
routes caused by carpooling
Answers
Answer:
A)
Reduced toll revenues would threaten public road maintenance budgets.
Explanation:
If cars will more than three people will not pay tall chargers, the city will collect fewer revenues from the toll stations as some cars will not pay. A significant decline in revenues that can affect road maintenance can influence the city to weigh against implementing that proposal.
Spreading the peak time traffic and increasing speeds is what the city hopes to achieve. The city would be happy if the average number of miles commuted remain the same. The only negative effect that could halt the implementation of the plan is reduced revenues.
Answer:A) reduce total revenues would threaten public road maintenance budgets.

What is the amount of money the Perkettes will need to deposit annually (rounded to the nearest two decimal places) to achieve their down-payment
goal?
Answers
The Perkettes will need to deposit $9,923.28 annually (rounded to two decimal places) to achieve their down-payment goal.
What is the deposit about?To calculate the annual deposit the Simons need to make in order to achieve their down-payment goal, we can use the formula for the present value of an annuity:
PV = PMT * (1 - (1 / (1 + r)ⁿ)) / r
where PV is the present value (the amount they need to save), PMT is the annual deposit, r is the interest rate (0.06), and n is the number of years (6). Since they already have $5,000 saved, we can plug that in as the PV and solve for PMT:
$45,000 = PMT * (1 - (1 / (1 + 0.06)⁶)) / 0.06
PMT = $8,169.09
So the Simons will need to deposit $8,169.09 annually (rounded to two decimal places) to achieve their down-payment goal.
To calculate the annual deposit the Perkettes need to make in order to achieve their down-payment goal, we can use the same formula as before:
PV = PMT * (1 - (1 / (1 + r)ⁿ)) / r
where PV is the present value (the amount they need to save), PMT is the annual deposit, r is the interest rate (0.06), and n is the number of years (6). Since they have not saved anything yet, we can set the PV equal to $45,000 and solve for PMT:
$45,000 = PMT * (1 - (1 / (1 + 0.06)₆)) / 0.06
PMT = $9,923.28

Algeria has a negative trade balance of $7 billion. If it is has a positive balance of goods of $10 billion, how much is its balance of services?
(NO the answer is NOT 17 billion, ive gotten that wrong.)
Answers
The balance of services for Algeria is -$3 billion, indicating a deficit or negative balance in the services trade.
A negative trade balance, also known as a trade deficit, occurs when the value of a country's imports exceeds the value of its exports. It means that the country is importing more goods and services than it is exporting, resulting in a deficit in its trade balance.
If Algeria has a negative trade balance of $7 billion and a positive balance of goods of $10 billion, then the balance of services can be calculated as follows;
Negative trade balance = Balance of goods + Balance of services
$7 billion = $10 billion + Balance of services
To find the balance of services, we can rearrange the equation:
Balance of services = Negative trade balance - Balance of goods
Balance of services = $7 billion - $10 billion
Balance of services = -$3 billion

B) Assuming that the Small Motor Division does not have excess capacity, compute the min-imum acceptable price for the transfer of the small motor to the Household Division.
C) Explain why the level of capacity in the Small Motor Division has an effect on the transfer price.
Answers
Answer:
A) Assuming that the Small Motor Division has excess capacity, compute the minimum acceptable price for the transfer of small motor LN233 to the Household Division.
If there is excess capacity, then LN233 can be sold only considering variable costs = $11 per unit.
B) Assuming that the Small Motor Division does not have excess capacity, compute the minimum acceptable price for the transfer of the small motor to the Household Division.
If the Small Motor Division currently produces and sells at full capacity, then the minimum selling price = variable cost + opportunity costs = $35 per unit (basically the same price as any outside buyer).
C) Explain why the level of capacity in the Small Motor Division has an effect on the transfer price.
If there is excess capacity, then the marginal cost of producing LN233 is equal to the variable cost, but if it is operating at full capacity, if it sells below normal price it would be losing money. One unit sold to another division is one less unit sold to an outside customer = less profit.

Perfect competition is thought of as a theoretical idea rather than something that applies to contemporary industry. This is solely attributable to the way that markets are naturally influenced by economic variables, which leads to a clustering of elements.
Criticisms of perfect competitionSome of the criticisms of perfect competition include:
It is frequently argued that the foundation of price theory for product markets, represents all agents as passive, omitting the active attempts to increase one's welfare or profits through price undercutting, product design, advertising, and innovation.Another criticism is that of who sets the price to be followed. The perfect competition model can thus be used to explain a centralized economy rather than a decentralized "market" economy.

Preble Company manufactures one product. Its variable manufacturing overhead is applied to production based on direct labor-hours and its standard cost card per unit is as follows:
1. What is the materials quantity variance for March?
2. If Preble had purchased 171,000 pounds of materials at $7.20 per pound and used 155,000 pounds in production, what would be the materials quantity variance for March?
3. What is the labor rate variance for March?
4. What is the labor efficiency variance for March?
5. What is the labor spending variance for March?
Answers
Labor efficiency variance = (Actual hour * Standard rate) - (Standard hour * Standard rate).
Labor efficiency variance = $404,600 F
What is Labor efficiency variance?By "efficiency of labor," we mean a worker's ability to produce more or better work, or both, over the course of a given amount of time.
1) Labor efficiency variance = (68,000 * $17) - ((30,600 * 3) * $17)
Labor efficiency variance = $1,156,000 - (91,800 * $17)
Labor efficiency variance = $404,600 F
2) Variance in direct labor worked divided by variance in labor efficiency
Variance in labor costs is $404,600 - $68,000.
Variance in labor costs = $336,600 F
3) Planned unit sold minus variable overhead equals variable manufacturing overhead cost.
Manufacturing variable overhead cost = 24,000 * $21
$504,000 is the variable manufacturing overhead cost.
4) Planned unit sold minus variable overhead equals variable manufacturing overhead cost.
Cost of variable overhead in production = 30,600 * $21
$642,600 is the variable manufacturing overhead cost.

From 1975-2015, inflation has ____ real wages for most workers in the U.S.
a. not changed
b. raised
c. not enough information
d. lowered
Answers
Answer:
hi, how are you?
Explanation:
From 1975-2015, lowered inflation has real wages for most workers in the U.S. The appropriate response is option D.
What is inflation?Inflation is the generalized rise in prices for goods and services. As the general price level rises, each unit of currency may buy fewer goods and services, hence inflation is related to a reduction in the purchasing power of money.
The main categories of inflation are as follows: Consumer-driven inflation price-driven inflation.
The overall rise in a nation's pricing for goods and services is referred to as inflation. Money loses value due to inflation, becoming progressively weaker over time.
In order to provide better comparisons throughout time, real wages have been adjusted to account for the impact of inflation. What has been discovered is that, when compared to other developed nations, inflation has decreased the salaries of the majority of American employees.
Hence, option D is an appropriate response.
