Answer:
The relation is a function
Step-by-step explanation:
Given
[tex](1, 2), (2, -1), (3,0), (4, 1),\ and\ (5, 1)[/tex]
Required
Determine if the points is a function or not
A relation can be expressed as: [tex](x_1,y_1), (x_2,y_2),(x_3,y_3)......(x_n,y_n)[/tex]
Where
[tex]x = domain[/tex]
[tex]y = range[/tex]
When any domain element occurs more than once, then the relation is not a function.
The domain of the above points are:
[tex]x = \{1,2,3,4,5\}[/tex]
In this case, no domain occur more than once; in other words, no x value occur more than once
Hence, the relation is a function

= 68
Lola's age is 14 more than 6 times Juan's age. The sum of their ages is 35. How old is each?
35 - 14 = 21
3 * 6 = 18
3.5 * 6 = 21
Thus Juan is around the age of 3.5 and Lola is 31.5 I believe

You read in a book on poker that the probability of being dealt three of a kind in a five-card poker hand is 0.02. What does this mean?
Answer:
there is a 2% chance of this happening xx
If we deal with 1000 poker hands then three of any kind will be in the form of fraction 1/ 50.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
The probability of being dealt three of a kind in a five-card poker hand is 0.02 or 1/50.
This shows that if we deal with 1000 poker face then three of any kind will be in the form of fraction 1/ 50.
Also, shows that how may poker hand we deal we always have 1/50 of them have three of kind.

find the vertex y= 4x*2 -16x+10
Answer:
I hope it helps U
Step-by-step explanation:
As given quadratic equation is ,
y= 4x*2 -16x+10
As general quadratic equation is,
y=ax^2+bx+c , we get a=4 , b=-16 , c=10
as a=4 and +ive so the parabola is up-down facing
vertex formula is X(vertex)= -b/2a putt values in this formula we will get x -coordinate of vertex,
X(vertex)= -(-16)/2*4
X(vertex)= 2
Now to find the Y- Co-ordinate just plug in the value of X in the given equation, hence
Y(vertex)=4(2)^2-16*2+10
Y(vertex)=-6
hence the vertex of given equation is (2,-6)

A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?
Answer:
523.3 cubic inches
Step-by-step explanation:
A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?
The shape of a basketball is spherical.
Hence:
The volume of a basketball = 4/3 × π × r³
From the question,
π = 3.14
r = radius = Diameter/2
r = 10 in/2 = 5 in
Hence:
The volume of the basketball
= 4/3 × 3.14 × 5³
= 1570 ÷ 3
= 523.33333333 cubic inches
Therefore, the approximate volume of the basketball = 523.3 cubic inches

Answer the Following Question with Explanation
Answer:
The answer's D.
Step-by-step explanation:
If 40 questions were put in and only 50% of them were used then only 20 questions were used. If you need 40 more questions and 80% of the qustions were used, then she wrote 50 questions.
========================================================
Explanation:
There are 60 questions total.
Amita made 40 questions, but only 50% were considered "good" to be used. So that means 0.50*40 = 20 questions were used.
This means 60-20 = 40 questions remain, and this must be the amount of "good" questions that Meena provided.
We're told that 80% of Meena's questions were considered "good". Let x be the total number of questions she provided.
80% of x = (number of "good" questions Meena offered)
0.80x = 40
x = 40/0.80
x = 50
Therefore, Meena wrote up 50 questions.

The equation x + 8 = 12 represents the number of balloons Dylan needs to decorate a place for a party. Which number line shows how many more balloons Dylan needs?
Answer:
4 balloons
Step-by-step explanation:
According to the problem, the data given are as follows,
Equation given = x + 8 = 12
Here X is showing the number of balloons which Dylan more needs to decorate.
So, by solving the equation, we get
X + 8 = 12
( by taking 8 to RHS )
X = 12 - 8
X = 4
Hence, Dylan need 4 more balloons to decorate for a party.

Give triangle ABC is a right triangle, and angle A is the right angle. If sin(B)=3/5, find the cos(B).
Answer:
Cos B = 4/5
Step-by-step explanation:
From the question given above, the following data were obtained:
Sine B = 3/5
Cos B =?
Recall:
Sine B = Opposite / Hypothenus
Sine B = 3/5
Therefore,
Opposite = 3
Hypothenus = 5
Next, we shall determine the Adjacent. This can be obtained as follow:
Opposite = 3
Hypothenus = 5
Adjacent =?
Hypo² = Adj² + Opp²
5² = Adj² + 3²
25 = Adj² + 9
Collect like terms
Adj² = 25 – 9
Adj² = 16
Take the square root of both side
Adj = √16
Adjacent = 4
Finally, we shall determine Cos B. This can be obtained as follow:
Hypothenus = 5
Adjacent = 4
Cos B =?
Cos B = Adjacent / Hypothenus
Cos B = 4/5
