Answer:

The probability more than 72% of the cardholders are carrying a balance is 0.2946

Explanation:

Test statistic (z) = (p' - p) ÷ sqrt[p(1-p) ÷ n]

p' is the sample proportion = 0.72

p is the population proportion = 0.74

n is the number of cardholders sampled = 140

z = (0.72 - 0.74) ÷ sqrt[0.74(1-0.74) ÷ 140] = -0.02 ÷ 0.037 = -0.54

The cumulative area of the test statistic is the probability that less than 72% of the cardholders are carrying a balance. The probability is 0.7054.

Probability (more than 72% of the cardholders are carrying a balance) = 1 - 0.7054 = 0.2946

Morin Company's bonds mature in 10 years, have a par value of $1,000, and make an annual coupon interest payment of $60. The mar
m_a_m_a [10]

Answer:

= $865.79

Explanation:

<em>The value of the bond is the present value (PV) of the future cash receipts expected from the bond. The value is equal to present values of interest payment plus the redemption value (RV).</em>

Value of Bond = PV of interest + PV of RV

The value of bond of Morin Company can be worked out as follows:

Step 1

PV of interest payment

PV = A ×  (1-(1+r)^(-n))/r

r- 8%, n- 10, A- interest payment = 60

PV of interest

= 60× (1- (1+0.08)^(-10)/0.08

= 402.60

Step 2

<em>PV of Redemption Value</em>

PV = RV × (1+r)^(-n)

= 1,000 × (1.08)^(-10)

= $463.193

Step 3

<em>Price of bond</em>

= $536.80 + 463.19

= $865.79

Lois has a balance of $970 on a credit card with an APR of 24.2%, compounded monthly. About how much will she save in interest o
Aleks04 [339]

Answer:

Lois will save $152.51 when she wil transfer her balance.

Explanation:

Amount to be paid in 1 year for original credit card is given as

P_1^{'}=P*(1+r_1)^t

Here P^{'}_1 is the amount to be paid after P is the balance which is 970, r_1 is the APR for first credit card which is 24.2% and t is compounding frequency which is 12 so

P_1^{'}=P*(1+r_1)^t\\P_1^{'}=970*(1+\dfrac{24.2}{12}\%)^{12}\\P_1^{'}=970*(1.0207)^{12}\\P_1^{'}=970*1.2707\\P_1^{'}=\$1232.61

Similarly for the second one the values are calculated as

P_2^{'}=P*(1+r_2)^t\\P_2^{'}=970*(1+\dfrac{10.8}{12}\%)^{12}\\P_2^{'}=970*(1.108)^{12}\\P_2^{'}=970*1.1135\\P_2^{'}=\$1080.10

The differnce of the two values is calculated as

P_1'-P_2'=1232.61-1080.10\\Difference=\$ 152.51

The difference is $152.51 which she could save.

The house that Jeanne inherited from her mother can rent for $1500/month, but Jeanne decides to allow her brother to stay there
OLga [1]

Answer:

The correct option is B,zero monetary cost but a $1,000 per month opportunity cost

Explanation:

Monetary cost also known as explicit cost is the actual costs incurred in running a business.But the business in this case is renting of the property,frankly speaking, Jeane has not incurred any cost in her property business,hence monetary cost is zero.

Opportunity is the cost or benefits from alternative course of action. Jeane not renting out the property on commercial basis is the alternative course of action in this case.Since the commercial letting gives $1500 and the letting to her brother gives $500, the difference between the two rents is $1000 which is benefits forgone from letting the house to her brother,that is the opportunity cost.
