The ability of an organism to change in its environment. It applies to development by environmental interactions and neural changes influenced by learning.
Answer:
The current bid/ask spread for Berkshire Hathaway Class A shares is $935
Explanation:
The computation of the current bid/ask price is shown below:
The Current bid/ask price = Ask price - Bid price
= $263,810 - $262,875
= $935
The commission amount should be ignored in the computation part. Hence, it will not be considered as it is not relevant.
Answer:
60 pizzas
40 pizzas
Explanation:
Marginal product measures the change in output as a result of a change in input by one unit
Marginal product = change in output / change in input
Marginal product for the 4th worker
Change in output = 360 - 300 = 60 pizzas
Change in input = 4 - 3 = 1 worker
Marginal product = 60 / 1 = 60
Marginal product for the 5th worker
Change in output = 400 - 360 = 40 pizzas
Change in input = 5 - 4 = 1
Marginal product = 40 / 1 = 40
It can be seen that marginal product decreased from 60 to 40 when the 5th worker was added. This illustrates diminishing marginal returns.
The law of diminishing returns says as more units of a variable input is added to a fixed income of production, output might increase at a point but after some time total output would increase at a decreasing rate and marginal product would be decreasing.
Answer:
D. Recession
Explanation:
Aggregate output in an economy declines during a recession. This is because economic activities are declining. When such occurs GDP declines. This is different from stagflation in the sense that during a recession, only real GDP declines. However, in a stagflation, the fall in GDP also results to the increase in inflation. During recessions, economic activities are low so is price level.
Answer:
The actual price = $1.08
Explanation:
The standard material price can be worked out as follows:
<em>Step 1: Work out the standard price of material using the material usage variance</em>
Standard price = Material usage variance/(standard quantity of material - actual quantity)
Standard quantity of material = standard qty per unit × actual production
= 4 × 17,000 =68,000
Standard price = 2,800/(68,000-64,000)= $0.7
<em>Step 2 : Work out the Actual material price using the material price variance</em>
Material price variance = (Standard price - Actual price )× Actual quantity of material
6,400 = (y - 0.7) × 17,000
6400 = 17,000y - 11,900
17,000 y = 6,400 + 11,900
y = 18,300/17,000= 1.08
The actual price = $1.08
