Answer: c. There is sufficient evidence to support the claim that the mean is greater than 23 miles per gallon.

Explanation:

When doing a research, there are 2 Hypothesis one must come up with which are the Null Hypothesis and the Alternative hypothesis.

The Null Hypothesis should state that there is no relationship between the variables which in this case would mean that new sedan, the Libra, will <em>not</em> average better than 23 miles per gallon in the city.

The Alternative Hypothesis on the other hand affirms the belief of the researcher which in this case is that new sedan, the Libra, <em>will </em>average better than 23 miles per gallon in the city.

As the null hypothesis was rejected by the evidence, it means that indeed the Libra mean is greater than 23 miles per gallon.

katovenus [111]

Answer:

The answer is $138.92

Explanation:

Solution

Given that:

Daryl today's Age = 30

The Retirement Age = 64

The Total Monthly Deposits = ( 64 - 30 ) * 12 = 408

Now,

In case of 12% Compounded Monthly , Interest Rate per month = ( 12% / 12 ) = 1%

Then,

The Effective Interest Rate per year = ( 1 + 0.12/12 )12 - 1 = 1.1268 - 1 = 0.1268 = 12.68%

So,

The Present value of Annual 25 Years withdrawal of $100,000 at time of Retirement = $100,000 * PVAF ( 12.68% , 25 )

= $100,000 * 7.4864

= $748,642.20

The Present Value of Money for nephew at time of Retirement = $1,000,000 * PVF ( 12.68% , 25 )

= $1,000,000 * 0.050535

= $50,534.52

Now

The Present Value of total Amount Required at time of Retirement = $748,642.20 + $50,534.52

= $799,176.70

Now

The monthly deposit be X

Which is,

= X * FVAF ( 408 , 1% ) = $799,176.70

= X * 5752.85 = $799,176.70

X = $138.918

Therefore, Monthly Deposit  for his retirement plan is = $138.92

Hart Manufacturing makes three products. Each product requires manufacturing operations in three departments: A, B, and C. The l
Serjik [45]

Answer:

Objective function:

Maximize Z: 30P1 + 25P2 + 28P3

Subject to:   2.00P1 + 1.50P2 + 3.00P3 ≤ 450 (Department A constraint)

                    2.50P1  + 2.00P2 + P3       ≤ 350 (Department B constraint)

                    0.25P1  + 0.25P2 + 0.25P3 ≤ 50  (Department C constraint)

                           P1, P2, P3                       ≥  0 (Non-negativity)

Explanation:

The objective function is formulated from the contribution margin of the three products. For instance, the contribution of Product 1 is $30, the contribution of Product 2 is $25 and the contribution of Product 3 is $28. Thus, the objective function will be 30P1 + 25P2 + 28P3.

The constraints were obtained from the departmental labour hours requirements for each product. For instance, Product 1 requires 2 hours in department A, Product 2 requires 1.50 hours in department A and Product 3 requires 3 hours in Department A. Thus, the constraint will be 2.00P1 + 1.50P2 + 3.00P3.

The standard cost of product 777 includes 2.0 units of direct materials at $6.00 per unit. During August, the company bought 29,
AfilCa [17]

Answer and Explanation:

The computation is shown below:

Total material variance = Actual quantity × Actual rate - Standard quantity × Standard rate

= 29000 × $6.3 - (16,000 units × 2) × $6

= $182,700 - $192,000

= - $9,300 favorable  

Material price variance = Actual quantity × Actual price - Actual quantity × Standard price

= (29,000 units × $6.3) - (29,000 units × $6)

= $182,700 - $174,000

= $8,700 unfavorable  

Material quantity variance =  Standard quantity × Actual quantity - Standard rate × Standard quantity  

= $6 × 29,000 units - $6 × (16,000 units × 2)

= $174,000 - $192,000

= -$18,000 favorable

The favorable is when the standard cost is more than the actual one while the unfavorable is when the standard cost is less than the actual one
