Answer:
C.
Step-by-step explanation:
When a data is continuous, the values it can take are the real numbers, this means it can take any value in an interval.
When a data is discrete, the values can take only certain values in an interval, this data usually refers to natural numbers.
In the case of the maximum capacities of various stadiums it is clear that their capacities can only be found in the natural numbers (a stadium cannot have a capacity of 4647576.56 people or any number with a decimal). Therefore, the data are discrete because it can take only some specific values.
Thus, the correct answer is C.
U count how many students were walking then multiply it by half itself
Mario says that the expression
has four terms: 4, 3, n, and 2. Mario is incorrect
<em><u>Solution:</u></em>
Given that the expression is:

Given that, Mario says that the above expression has four terms
But Mraio is incorrect
Because the given expression has two terms only
4 is one of the term
is another term
So there are totally 2 terms only
A term can be a signed number, a variable, or a constant multiplied by a variable or variables
Here 3 is a constant multiplied by 
So,
is one term
Each term in an algebraic expression is separated by a + sign or - sign
Thus there are two terms in mario expression
