Which set of ordered pairs represent a function
lara31 [8.8K]

Answer:

A relation is just a set of ordered pairs (x,y) . In formal mathematical language, a function is a relation for which: if (x1,y) and (x2,y) are both in the relation, then x1=x2 . This just says that in a function, you can't have two ordered pairs with the same x -value but different y -values.

You are trying to answer a multiple choice question on a standardized test. There are five choices. If you get the question righ
mestny [16]

Answer: -0.6

Step-by-step explanation:

Given : The number choices to a question : 5

Let we have no idea what the right answer is, so you pick one of the choices at random.

The probability that the answer is correct : P(x)=\dfrac{1}{5}=0.2

Then , the probability of the answer is not correct : P(x')=1-0.2=0.8

Then , the expected value of the number of points you get :-

E(x)=P(x)\times\text{Points on x}+P(x')\times\text{Points on x'}\\\\\Rightarrow\ E(x)=0.2\times(1)+0.8(-1)=-0.6

Hence, the  expected value of the number of points you get = -0.6

Using the Distance Formula and the Pythagorean Theorem, find the distance, to the nearest tenth, from F (5,5) to G (−3,−1).
kvasek [131]

Answer:

<h2>The answer is 10 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

F (5,5) , G (−3,−1)

The distance between them is

|FG|  =  \sqrt{( {5 + 3})^{2} +  ({5 + 1})^{2}  }  \\  =  \sqrt{ {8}^{2}  +  {6}^{2} }  \\  =  \sqrt{64 + 36}  \\  =  \sqrt{100}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 10 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>10 units</h3>

Hope this helps you

professor190 [17]

A complete circle is 360° and is divided into 4 equal parts: North, South, East, and West. Each of these will equal 90°. 90°-23°=67° , so you would be driving 67° North of East. 67° is an acute angle.
