Answer:

$24.7million

$97.86million

$9.89million

Explanation:

 

From the sample , the lowest number is 16.3 and the highest number is 41, the range is

41-16.3

=$24.7 million

 

 

Σ \frac{(x-x_{mean} )^2}{n}

 

In the sample given the mean is . : (41 +40 +38+ 32+ 23+ 22+ 20+ 18+ 17.8 +16.3  )/10

mean=26.81

 

Using that, we can find the variance:

[(41-26.81)^2+(40-26.81)^2+(38-26.81)^2+(32-26.81)^2+(23-26.81)^2+(22-26.81)^2+(20-26.81)^2+(18-26.81)^2+(17.8-26.81)^2+(16.3-26.81)^2]/10=97.86million

 

The standard deviation is just the square root of the variance:

standard deviation=√(var)

 

, the standard deviation is the square root of 97.86, which equals ​$ 9.89 million

The replacement cost of an inventory item is below the net realizable value and above the net realizable value less the normal p
Andrews [41]

Answer:

D. Replacement cost.

Explanation:

As we know that the inventory should be recorded at the cost or market value whichever is lower

Given that

Original cost is less than the net realizable value subtract the profit margin

So we assume the following figures

Original cost $10

Net realizable value 9

Replacement cost 8

NRV less normal profit margin 7

As if we compare the original cost and replacement cost so the lower value is of replacement cost

hence, the same is to be considered

Therefore the correct option is D.

leonid [27]

Answer:

Decrease by $1

Explanation:

Given:

Old data:

Q0 = 2,000 units

P0 = $20

Total revenue before change = 2,000 x $20 = $40,000

After change in Price.

Q1 = 2,100 units

P1 = $19

Total revenue After change = 2,100 x $19 = $39,900

Computation of Marginal Revenue:

Marginal Revenue = (P1 - P0) / (Q1 - Q0)

= ($39,900 - $40,000) / (2,100 - 2,000)

= -100 / 100

= $(-1)

Marginal revenue will decrease by $1
