Does this graph represent a function? Why or why not?

Mathematics
1 answer:
ExtremeBDS [4]3 years ago
5 0

A Function is defined as the relation between the input and the output where one input can have only one output

When graphing functions, the x-axis denotes the inputs and the y-axis denotes the output of the function

Looking at the graph, we see that for one input (point on the x-axis) we have only one output (point on the y-axis)

Hence, we can say that this graph represents a function

The value of c is equal to _____.
DENIUS [597]

For this case we have that by definition, the Pythagorean theorem states that:

c = \sqrt {a ^ 2 + b ^ 2}

Where:

a, b: Are the legs

c: It is the hypotenuse

According to the figure we have to:

a = 20\\b = 21

Substituting in the formula we have:

c = \sqrt {(20) ^ 2 + (21) ^ 2}\\c = \sqrt {400 + 441}\\c = \sqrt {841}\\c = 29

Option D

Sammy and David were selling water bottles to raise money for new football uniforms famous or 5 water bottles for every 3 water
ANTONII [103]
In the given question, we come to know that Sammy sold 5 bottles for every 3 water bottles sold by David. In this case we get the ratio as 5:3
Now this ratio indicates that the total number of bottles can be divided into 8 parts for finding out a single part. the total number of water bottles that are sold by Sammy and David together are 160.
Now on dividing this total number of bottles by 8 we get the 20 as one part.
The,
Number of Bottles sold by Sammy = 5 * 20
                                                         = 100
Number of bottles sold by David = 3 * 20
                                                   = 60
So Sammy sold 100 water bottles and David sold 60 water bottles from the total of 160 water bottles.

Dalgliesh the detective fancies himself a shrewd judge of human nature. In careful tests it has been discovered that he is right
Dafna11 [192]

Answer:

The probability that Jones is lying is 6/7

Step-by-step explanation:

First we will list out 2 different cases when the outcome is a lie

1.probability that Jones tells lies is = 0.6 and probability that dalgiliesh analyses it correctly is 0.8

So the probability that dagliesh correctly analyses that he is telling lies is 0.8*0.6=0.48

2.Probability that Jones tells truth is 0.4 and if dagliesh analyses it incorrectly (which has a probability of 0.2) the outcome(as analysed by dagiliesh) is a lie

So probability that dagliesh analyses Jones truth as a lie is 0.2*.0.4=0.08

Total probability of outcome being a lie is 0.48+0.08=0.56

But we need the probability of Jones actually saying a lie which is nothing but 0.48/0.56= 6/7
