Answer:

The better deal is 4 bagels for $3.00.

The fractions you would compare would be:

11 / 10 = 1.10 and

3 / 4 = 0.75

A "deal" would refer to the better value. In this case the better deal has a lower ratio of dollars to bagels.

Step-by-step explanation:

Which is the better deal?

First, you have to get the 10 and 4 to the same number.

10 x 4 = 40

4 x 10 = 40

Then, you multiply $11 by the same number as the 10.

Now multiply $3 by the same number as the 4.

$11 x 4 = $44

$3 x 10 = $30

So, which one has the lowest prize?

<u>Donny's Bagels</u>

What fractions do you compare with the better deal?

Bob's Bagels: 44/40

Donny's Bagels: 30/40

Now, you'll have to make these fractions as low as possible.

Bob's Bagels:

44 divided by 4 = 11

40 divided by 4 = 10

Donny's Bagels:

30 divided by 5 = 6

40 divided by 5 = 8

The fractions are: 11/10 and 6/8. But, 11/10 is an improper fraction.

To make it a mixed number, you'll have to follow these steps:

  1. Divide the numerator by the denominator: 11 divided by 10 = 1.1
  2. Write down the whole number answer: 1
  3. Then write down any remainder above the denominator: 1 1/10

Bob's Bagels fraction: 1 1/10

Will the better deal have a lower or higher ratio of dollars per bagel?

The better deal will have a lower ratio of dollars per bagel.

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.
