Answer:

D. {(7, 11), (0,5), (11, 7), (7,13)}

Step-by-step explanation:

Because the relations (7, 11), (7,13) are false.

f(7) = 11

f(7) = 13

=> 11 = 13 (F)

Answer:

The correct answer option is: D. {(7, 11), (0,5), (11, 7), (7,13)}.

Step-by-step explanation:

We are given some paired values of inputs and outputs (x and y) for a function and we are to determine whether which of them is not a function.

For a relation to be function, no value of x should be repeated. It means that for each value of y, there should be a unique value of x (input).

In option D, two of the pairs have same value of x. Therefore, it is not a function.

{(7, 11), (0,5), (11, 7), (7,13)}

Vincent and Jean are two cooks who work in a village. Each of them can either bake cakes or make pizzas. Every ingredient is rea

babymother [125]

Answer:

a) Jean b) Jean c) Vincent d) Jean

Step-by-step explanation:

We are given the following information in the question.

Vincent can bake 10 cakes or make 5 pizzas

Jean can bake 12 cake or make 8 pizzas.

a) Absolute advantage of baking cake

Jean has the absolute advantage of baking cake as he can bake more cakes as compared to Vincent.

b) Absolute advantage of making pizza

Jean has the absolute advantage of making pizza as he can make more pizzas as compared to Vincent.

In order to find comparative advantage, we find the opportunity cost which can be defined as:

$\text{Opportunity Cost} = \displaystyle\frac{\text{What one sacrifices}}{\text{What one gains}}$

c) Comparative advantage in baking cakes

Opportunity cost of Vincent for baking cakes = $\frac{5}{10} = \frac{1}{2}$

Opportunity cost of Jean for baking cakes = $\frac{8}{12} = \frac{2}{3}$

The less is the opportunity cost the better, hence, Vincent has comparative advantage in baking cakes.

d) Comparative advantage in making pizzas

Opportunity cost of Vincent for making pizzas = $\frac{10}{5} = 2$

Opportunity cost of Jean for making pizzas = $\frac{12}{8} = \frac{3}{2}$

The less is the opportunity cost the better, hence, Jean has comparative advantage in making pizzas.

Colin found 22 more mushrooms that sophie did while they were out picking them in the forest. On the way home Sophie asked Colin

Rasek [7]

Answer:

11 mushrooms

Step-by-step explanation:

Let's take two sets of numbers that fulfill the requirements (2 and 24 | 5 and 27)

In the first case, there are 26 mushrooms, and to have an equal amount they each need 13. Collin had to give 11 mushrooms to Sophie.

In the second case, there are 32 mushrooms, and they both need 16 each. So in this case, Collin also had to give 11 to Sophie.

The answer is 11 mushrooms.
