The set of integers is closed under the operation of addition.
Brut [27]

Answer:

A: 2+27=29

B: The sum of the integers 2 and 27 is the integer 29, which demonstrates that integers are closed under addition.

Step-by-step explanation:

Since, closed property of addition for a set A is defined as,

∀ x, y ∈ A ⇒ x + y ∈ A,

∵ Set of integer is closed under multiplication,

If Z represents the set of integer,

Then 2, 27 ∈ Z  ⇒ 2 + 27 = 29 ∈ Z,

Hence, the equation illustrates given statement,

2+27 = 29

The statement that correctly explains given statement,

The sum of the integers 2 and 27 is the integer 29, which demonstrates that integers are closed under addition.c

inysia [295]

Answer:

Continuous

Step-by-step explanation:

Here we are asked to determine that the data given to us in form of rates of pizza and the toppings is discrete or the continuous.

The discrete data always come in integers where as the continuous data can come in decimals too. For example the number if student in a class is always a discrete data where as the weight of the students in a class is continuous data.

Here we can see that the cost of pizza and the toppings are in decimals. Hence here the data is continuous
