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.

What is the distance between the points M (-3, 7) and N (a, b)?
Answer: [tex]\sqrt{ (-3-a)^2 + (7-b)^2 }[/tex]
Explanation:
We plug the given coordinates into the distance formula
[tex]d = \sqrt{ (x_1-x_2)^2 + (y_1-y_2)^2 }\\\\[/tex]
There isn't much we can do from there since we don't know the values of 'a' or 'b'. You could expand out each binomial, but it's more simplified being factored like that.
Identify the slope and y-intercept from the following equation.
Answer:
The slope is 2/5 and the y intercept is -4
Step-by-step explanation:
The slope is always the coefficient to x
Answer:
slope = [tex]\frac{2}{5}[/tex] , y- intercept = - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{2}{5}[/tex] x - 4 ← is in slope- intercept form
with slope m = [tex]\frac{2}{5}[/tex] and y- intercept c = - 4

(10, y) and (3, 4); m= -2/7 find missing value
Answer:
y2 -y1 =4 - y = 2 y has to = 2 because your slope m= - 2/7
x2-x1 =3-10 = -7
Step-by-step explanation:
( 10 , y ) (3 , 4)
x1 y1 x2 y2
We have that for the Question "(10, y) and (3, 4); m= -2/7 find missing value" it can be said that
The value of y is
y=8
From the question we are told
(10, y) and (3, 4); m= -2/7 find missing value
Generally the equation for the slope m is mathematically given as
[tex]m=\frac{y2-y1}{x2-x1}\\\\Therefore\\\\m=\frac{y2-y1}{x2-x1}\\\\-2/7=\frac{4-y}{3-10}\\\\-2/7*-7=4-y\\\\y=4((-2/7)*-7)\\\\[/tex]
y=8
Therefore
The value of y is
y=8

Jenna saves $2,500 per year in an account that earns 10% interest per year, compounded annually. Jenna will have(A $411,234) (B $425,352) (C $449,739) saved in 30 years. Her account balance is a result of Jenna’s(A annuity payments)(B lump-sum payment) .
Answer:
The answer is $43623.50Step-by-step explanation:
This problem is on compound interest.
the expression for compound interest is given as
A=P(1+r)^t
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
Given data
P= $2,500
r= 10/100= 0.1
t= 30 years
substituting into the expression for compound interest and solving for A we have
A=2500(1+0.1)^30
A=2500(1.1)^30
A=2500*17.449
A=$43623.50
The final amount is $43623.50
Her account balance is a result of Jenna’s(A annuity payments)

Which of the following statements is TRUE about parallel lines pq and rs?
a° and c° are alternate interior angles
a° and c° are alternate exterior angles
a° and c° are corresponding angles
a° and c° are vertical angles
Answer:
a and c are alternate interior angles
For the parallel lines pq and rs a° and c° are alternate interior angles. Option A is correct.
What are parallel lines?Parallel lines are defined as identical lines with identical orientations, parallel lines never intersect each other but meet at infinity.
Here,
When two parallel lines is intersect by a transversal line then the angles made facing the region between the parallel lines are said to be interior angles, And as we know that alternate angles for parallel lines are always equal. So a° and c° are alternate interior angles.
Thus, a° and c° are alternate interior angles.

The annual profit at a chain of stores is normally distributed with a mean of $61,000 and a standard
deviation of $23,000. The stores in the top 5% of annual profit were rewarded with a celebration. What
was the annual profit required to have a party?
Answer: $98,835.
Step-by-step explanation:
Given: Annual profit at a chain of stores is normally distributed with a mean ([tex]\mu[/tex]) of $61,000 and a standard deviation([tex]\sigma[/tex]) of $23,000.
Let [tex]x[/tex] denoted the profit.
Let [tex]x_0[/tex] be the minimum profit required to have a party.
The stores in the top 5% (i.e. 0.05) of annual profit were rewarded with a celebration.
i.e. [tex]P(x>x_0)=0.05[/tex]
[tex]\Rightarrow\ P(\dfrac{x-\mu}{\sigma}>\dfrac{x_0-61000}{23000})=0.05\\\\\Rightarrow\ P(z>\dfrac{x_0-61000}{23000})=0.05\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\\Rightarrow\ \dfrac{x_0-61000}{23000}=1.645\ \ [\text{critical z-value for p-value 0.05=1.645}]\\\\\Rightarrow\ x_0-61000 =1.645\times 23000\\\\\Rightarrow\ x_0-61000 =37835\\\\\Rightarrow\ x_0=37835+61000\\\\\Rightarrow\ x_0=98835[/tex]
Hence, the annual profit required to have a party was $98,835.

Sally received a $30 gift card that could be used to download songs. After she downloaded 7 songs , she had $15 remaining on her gift card. If each song costs the same amount to download, what is the cost of one song?
Answer:
Step-by-step explanation:
2 dalliers and 14 cents
Answer:
$2.14285714286 or $2.14
Step-by-step explanation:
This is quite simple.
#1. Take-away $15 from $30 because "$15 remain"ed.
#2. Then you get $15 dollars and divide that by 7, because she used the "same amount to download" each song so you divide 15 among 7 equally.
#3. There you go! You have the answer! it's: $2.14285714286 or $2.14 if simplified.
