What is the domain and range? {(4,2), (-9,2), (5,4), (4,17)}

Mathematics

ExtremeBDS [4]3 years ago

Answer:

Domain = {4,-9,5}

Range = {2,4,17}

Step-by-step explanation:

We are given ordered pairs as

{(4,2), (-9,2), (5,4), (4,17)}

This is a subset of cartesian product AXB where

A = {4,-9,5} and B = {2,4,17}

Note: Repeated values are written only once in the set.

Hence we find that 4 is mapped on to 2 and 17,

-9 to 2 and 5 to 4

Domain = I item in the ordered pair of mapping =  {4,-9,5}

Range = II item in the ordered pair of mapping =  {2,4,17}

Hey there!!

What is a coordinate form?

... Coordinate form is written as ( x , y )

What is domain?

... Domain are also called as the 'x' values.

What is the range?

... Range is the other word for the 'y' values.

<em>Given ordered pairs :- </em>

( 4 , 2 ) ; ( -9 , 2 ) ; ( 5 , 4 ) ; ( 4 , 17 )

<em>Hence, the domain is :- </em>

... { 4 , -9 , 5 )

<em>Hence, the range is :- </em>

...  { 2 , 4 , 17 )

<em>Remember :- The values "can not" be repeated! </em>

<u><em>Hope my answer helps!!</em></u>

Three men and seven women are waiting to be interviewed for jobs. If they are all selected in random​ order, find the probabilit
sammy [17]

Answer:

1/50

Step-by-step explanation:

Given that:

  • Three men: 3
  • Seven women = 7
  • Total number of people: 7+3 =10

We need to find the probability that no man will be interviewed until at least two women have been interviewed. So there are two possible probabilities are:

1. One man and two women => P(1 man and 2 women) = 3/10*2/9 = 1/15

2. Three women => P(3 women) = 3/10

Hence, the probability in this situation is: 1/15*3/10 = 1/50

A rectangular flying carpet is 1 1/2 m wide and 2 m long what is the area of the carpet
d1i1m1o1n [39]

Hi there! :)

<u>Answer:</u>

The area of the carpet is <u>3m²</u>.


Step-by-step explanation:

First off, the formula to calculate the area of a rectangle is this: A = L × W

Where "A" is the area, "L" the length and "W" the width.

Now that you have that, replace all the information you know in the equation in order to find the value of "A", which is what we are looking for:

- Just keep in mind that 1 1/2 is the same thing as 1.5

- The term "wide" is used to give the "width"

- The term "long" is used to give the "length"


A = L × W

A = 2 × 1.5

<u>A = 3</u>


There you go! I really hope this helped, if there's anything just let me know! :)

We know that

reference angle is between terminal side and x-axis

so, the other side will be terminal position

so, we can write as

The positive acute angle formed by the <u>terminal</u> side of an angle in standard position and the x-axis is called a reference angle.

So,

option-C
