The general equation to represent the enrollment of the school each year after 2000  = 1200 +35 n    

where n = number of years after 2000.

Step-by-step explanation:

Here, according to the question:

The initial number of students enrolled in the school = 1200 students

The number of students increased each year  = 35 students

Now if the initial year is 2000, then the number of student in the first year

= Initial enrollment  +  ( n  x Number of students increasing each year )

where n : The total number of years after 2000

So, the number of students in first year after 2000 for n = 1 is

1200 + ( 1 x 35)  = 1235

The number of students in second year after 2000 for n = 2  is

1200 + ( 2 x 35)  = 1270

The number of students in third year after 2000 for n = 3 is

1200 + ( 3 x 35)  = 1305

Hence, the general equation to represent the enrollment of the school each year after 2000  = 1200 +35 n    where n = number of years after 2000.

Answer:

Therefore Y = 1200+35 (T-2000)

T is variable.

Step-by-step explanation:

Variable : A variable represent many numbers.

Given that the enrollment of a school was  1200.

The increase rate per year is 35.

T = the year after 2000.

Since the increase rate per year is 35.

Therefore the number student increase =  35 (T-2000)

Let Y represent total number of student on T year.

Therefore Y = 1200+35 (T-2000)

Where T is a year after 2000.

Here T is variable.

Paul has 16 baseballs and 12 golf balls what is the ratio of balls to golf balls
Veronika [31]
Ratio is just a fraction in other form. To create ratio we can just make fraction and transform it into ratio, so
\frac{baseballs}{golf bals} = \frac{16}{12} =16:12
Now we can simplify the ratio/fraction
\frac{16}{12} = \frac{4}{3} = 4:3 - its the result

Is a relation always a function? Is a function always a relation? Explain.
katen-ka-za [31]

A function is always a relation but relation is not always a function

<u>Solution:</u>

Given that, we have to explain Is a relation always a function and is a function always a relation

Note that both functions and relations are defined as sets of lists.  

In fact, every function is a relation. However, not every relation is a function.  A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y.

That is, given an element x in X, there is only one element in Y that x is related to.

For example, consider the following sets X and Y. Let me give you a relation between them that is not a function;

X = { 1, 2, 3 }

Y = { a , b , c, d }

Relation from X to Y : { (1,a) , (2, b) , (2, c) , (3, d) }

This relation is not a function from X to Y because the element 2 in X is related to two different elements, b and c

Relation from X to Y that is a function: { (1,d) , (2,d) , (3, a) }

This is a function since each element from X is related to only one element in Y. Note that it is okay for two different elements in X to be related to the same element in Y. It's still a function, it's just not a one-to-one function.

So, we can say that function is a type of relation.

Which means whatever a function occurs, it will be a relation from one set to other.

But when a relation occurs it may be a function but need not be always a function.

Hence, a function is always a relation but relation is not always a function.

just olya [345]

Answer:

Therefore, the conclusion is valid.

The required diagram is shown below:

Step-by-step explanation:

Consider the provided statement.

Premises: All good students are good readers. Some math students are good students.

Conclusion: Some math students are good readers.

It is given that All good students are good readers, that means all good students are the subset of good readers.

Now, it is given that some math students are good students, that means there exist some math student who are good students as well as good reader.

Therefore, the conclusion is valid.
