Compare and contrast a postulate , theorem and a conjecture
Answer:
Postulates and conjectures are similar in that they are both used in mathematical proofs. The difference between them is that whilst a conjecture is a opinion that is put forward without proof, and that simply represents a belief, a postulate it something that is assumed true (but still does not have any proof behind it).
Step-by-step explanation:
Answer: Postulate – this is also called as axiom. This study is accepted without asking for any proof. This is considered as true without further proof. IT is simply considered as self-evident. It is usually agreed by anyone to be true and acceptable.
Example of postulate is to prove a simple triangle as congruent.
While conjecture – considered as proposition in which it needs to provide value proof or evident in order for it to be considered as true.
Examples of conjecture are four color theorems and Fermat’s Last theorem.

The local craft fair charges the vendors a flat fee of $15 plus $5 for each hour that they spend at the fair. If the vendor owed how many hours did he remain at the craft fair ?
Answer:
Equation should be: 15x + 5 = y
Step-by-step explanation:
I do not know the amount of money that he owed
For Example :
15(12) + 5 = y
180 + 5 = y
y = 185

(a) Find the slope-intercept form of the equation of the line.
Answer:
y=28/3x+6
Step-by-step explanation:
If you use the slope formula, y2-y1
_____\
x2-x1
You would get that the slope is 23/3 and you can see the y-intercept is 6 so you would get y=28/3x+6.

Answer:
f(4) = -28
Step-by-step explanation:
f(x) = -[tex]x^{2}[/tex] - 6x + 12
f(4) = -[tex]4^{2}[/tex] - 6(4) + 12
f(4) = -16 - 24 + 12
f(4) = -40 + 12
f(4) = -28

franco:1/4=0.25
Step-by-step explanation:
tried my best hope its right :)
Answer:
Maria: 1/3 cups for each gallon
Step-by-step explanation:
Maria: 2/3 for every 2 gallons. 2/3:2
Franco: 1 1/4 for every 5 gallons. 1 1/4/:5
Okay, so I'm actually going to do it my way.
Maria : [tex]\frac{2}{3} = 4/6\\\frac{4}{6} /2 =2/6[/tex]
So, I simply turn it into a bigger fraction and cut it in half!
So, Maria uses 1/3 of a cup for each gallon

this fall 126 students participated in the soccer program, while 54 played volleyball. what was the ratio of soccer players to volleyball player?
Answer:
126:54, or
63:27,or
7:3
Step-by-step explanation:
we can see that 126 can be divided by 2, and so can 54, so we reduce to #2,
we can see #2 can be divided by 9, so we get to #3

What is the percent of change from 5,000 to 8,000?
Step-by-step explanation:
% change = (new - original)/original × 100
= (8,000 - 5,000)/5,000 × 100
= 3,000/5000 × 100

Error Analysis A store is instructed by corporate headquarters to put a markup of 43% on all
items. An item costing $7 is displayed by the store manager at a selling price of $3. As an
employee, you notice that this selling price is incorrect. Find the correct selling price. What was the
manager's likely error?
The correct selling price is $0 (Round to the nearest dollar as needed.)
Answer:
$10
Step-by-step explanation:
To calculate markup, you take you cost and then multiply it by the markup percentage (in decimal form), then add that number to the original cost. So the formula will look like this.
Selling Price = Cost + (Cost X Markup Percentage)
Let's use X to be the selling price you are looking for.
X = $7 + ( $7 x 0.43) 0.43 is the decimal value of 43 percent
Work on the numbers in parentheses first:
$7 x 0.43 = $ 3.01
now add that to the original cost:
$7 + $ 3.01 = $ 10.01
Round to the nearest dollar and you have $10.
The manager made the mistake of multiplying the markup percentage and the original cost.
$7 x 0.43 = $ 3.01
He subtracted the markup instead of adding it to the original cost.

Which statement best illustrates using the vertical line test to determine if the graph below is a function of x?
The graph is not a function of x because the line x = 0 intersects the graph at two points.
The graph is a function of x because the line x = 5 does not intersect the graph.
The graph is not a function of x because the line y = 0 intersects the graph at two points.
The graph is a function of x because the line y = 5 does not intersect the graph.
Answer:
C: The graph is not a function of x because the line y = 0 intersects the graph at two points.
Step-by-step explanation:
The line y = 0 will intersect the ellipse at the points, (-4 , 0) , (4 , 0)

The intersection of a circle and a regular hexagon can be....
-two line segments
-a triangle
-two points
-a trapezoid
Answer: two points
Step-by-step explanation:
The intersection of a circle and a regular hexagon can be two pints option (C) two points is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The intersection of a circle and a regular hexagon.
As we know, the polygon is a geometric figure with a finite number of sides in two dimensions.
On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
If the circle and regular hexagon will intersect on a coordinate plane then it will create two intersection points.
Thus, the intersection of a circle and a regular hexagon can be two pints option (C) two points is correct.
