Answer: c). according to the ppf, as we produce more of one product, eventually we have give up more and more of the other product.
Explanation: PPF shows all possible combination of goods that a country can produce with its limited resources. The slope of a PPF is the opportunity cost which shows the units of goods that must be sacrificed to gain more and more units of the other good. As we move down the PPF the opportunity cost increases. This means that <em>more and more units of a good must be sacrificed to gain additional units of the other good</em>.
Answer:
The options are given below:
A) competitively exclude other predators.
B) prey on the community's dominant species.
C) allow immigration of other predators.
D) reduce the number of disruptions in the community.
E) prey only on the least abundant species in the community.
the correct option is B
Explanation:
Keystone species refers to a predator which prevents a particular herbivorous species from wiping out the dominant plant species. If the number of prey are low, the keystone predators can be less abundant and still be effective. Keystone species have a disproportionately large effect on its environment relative to its abundance.
Therefore, by preying on a community's dominant species, keystone predators help to maintain the species diversity in the community, because they ensure that the dominant predators do not totally wipe out the various organisms present in the ecosystem.
Answer:
1. 120 hot dogs per day
2. $1,920
3. Inelastic
4.200
Explanation:
1. Break even is a term given to a situation where there is no profit or loss made by an organization for product sales.
Formula is;
Fixed cost /contribution per unit, where contribution per unit is selling price - variable price.
Solution.
Since Total fixed cost =$1,200, Selling price=$16, Variable costs=$6
=Fixed costs/(Selling price - Variable costs).
= $1,200/($16 - $6)
=$1,200/$10
=120 hot dogs.
2. Break even point in dollar sales volume. This refers to the number of products that would be produced and sold to cover production cost.
Formular is ;
Fixed cost/contribution per unit× Sales price per unit.
Solution
=Fixed costs/(Selling price - Variable costs)× Selling price.
=$1,200/($16 - $6)×$16
=$1,200/$10×$16
=$1,200×$16/$10
=$19,200/$10
=$1,920
3. The demand would be inelastic. Inelastic demand is when the demand of buyers does not change as much as changes in price.
4. Achieve level of sales target. This is when management wanted to know the sales level at which targeted profit will be achieved.
Formula
Fixed costs + Target profit/Contribution per unit
Solution.
=Fixed costs + Target profit/(Selling Price - Variable costs)
= $1,200 + $800/($16-$6)
=$1,200 + $800/($10)
=$2,000×/$10
=$200
=200 cases would needed to sell
Answer:
In order to make a decision utilizing a decision tree, you must:___________
b. begin at Time 0 and work towards the most distant point in time.
Explanation:
Decision trees are built up by starting from the present with the overarching objective (goal) in mind. Then, one classifies the information along various branches and leaf nodes, with each branch representing the outcome of an alternative route or a question answered based on the likelihood of the event happening. Each leaf node represents a class label (decision taken after computing all attributes). This structure can be used to predict likely values of data attributes.
