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.
Step-by-step explanation:
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 : 
Then , the probability of the answer is not correct : 
Then , the expected value of the number of points you get :-

Hence, the expected value of the number of points you get = -0.6
Answer:
<h2>The answer is 10 units</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula

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

We have the final answer as
<h3>10 units</h3>

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.
