Answer:
16.9 months
Explanation:
Recovery time = Refinancing cost / Monthly savings
= $2,500 / $148
= 16.9 months
Answer:
probability = 0.008
probability = 0.0256
Explanation:
we know here probability of defective is 0.2
so probability of not defective is 1 - 0.2 = 0.8
as we know 3 item is arrive off process line in succession
so The probability that an item is defective is
as P(defective) = 0.20
as all item are independent so
probability that all three items are defective is
probability = 0.20 × 0.20 × 0.20 = 0.008
and
probability that exactly 3 of next 4 are defective
so number of way that can choose 3 out of 4 is
= 
= 4
so as all are independent probability is
probability = ( the number of way to choose 3 out of 4 ) × ( 3 item defective ) × ( 1 item not defective )
probability =
× 0.2³ × ( 1- 0.2)
probability = 4 × 0.008 × 0.8
probability = 0.0256
Answer:
B: Purchasing a new computer
Explanation:
Investing your money in a new computer does not teach you new skills so it would not be counted as an investment in human capital. Obtaining a college degree, attending a first-aid class, and paying for cooking lessons enhances your creativity and skills so they are the perfect examples of investments in human capital. Moreover, one of the major characteristics of investing in human capital is that they are intangible so that's another reason why purchasing a new computer cannot be categorized as an investment in human capital.
Answer: Marginal cost under demand and supply theory. Answer is 80
Explanation: QD 100-4P, Marginal Cost =S4,QS =6P -20. So
the calculation goes thus = QS=6p-20
Inputing Marginal value of 4 equates 100-4(4)
100-16 = 84
QS=6(4)-4
24-20=4
profit maximisation =QD-QS
84-4=80
Answer:
I will use the Omega network configuration if the economic factor is the determining one.
The total cost for the Omega network using the 4x4 switches will be $12,800, unlike the Butterfly network that can use the 16x16 switches that will cost $24,000.
Explanation:
The Omega network configuration will use the 4x4 switches which cost $50 each. The total number of switches required = 4,096/16 = 256. The total cost for 4x4 switches = 256 * $50 = $12,800. This is better than the Butterfly network configuration that can use the 16x16 switch, costing $1,500 x 16 (4,096/256) = $24,000.
