Answer:
end point of a segment X₂ = - 8 ; Y₂ = 21
Step-by-step explanation:
given;
midpoint = ( Mx = -4 , My = 13 )
endpoint ₁ = ( X₁ = 0 , Y₁ = 5 )
find the other endpoint ₂ ( X₂ , Y₂)
use the mid point formula to get the other endpoint:
Mx = ( X₁ + X₂ ) / 2 My = ( Y₁ + Y₂ ) / 2
- 4 = (0 + X₂) / 2 13 = (5 + Y₂) / 2
-8 = 0 + X₂ 26 = 5 + Y₂
X₂ = -8 Y₂ = 21

What is number system?Number System is a method of representing Numbers on the Number Line with the help of a set of Symbols and rules. These symbols range from 0-9 and are termed as digits. Number System is used to perform mathematical computations ranging from great scientific calculations to calculations.
Positive Numbers: Numbers that are represented on the right side of the zero are termed as Positive Numbers. The value of these numbers increases on moving towards the right. Positive numbers are used for Addition between numbers. Example: 1, 2, 3, 4, …
Negative Numbers: Numbers that are represented on the left side of the zero are termed as Negative Numbers. The value of these numbers decreases on moving towards the left. Negative numbers are used for Subtraction between numbers. Example: -1, -2, -3, -4, …
as per the situation given,

Point estimate is Select one: a. A statistical that estimates a population parameter b. A range of possible values for a population parameter. c. Always equal to the number or samples d. Equal to the population mean
Answer:
a. A statistical that estimates a population parameter
Step-by-step explanation:
A point estimate is a mathematical or statistics term that describes that is used as a means of revealing an estimated value of some parameter. It utilizes a single value, which can sometimes be the statistic mean to carry out the process of point estimation.
Hence, in this case, the correct answer is Option A: A statistical that estimates a population parameter

Answer:
1. I= $36, NB = $336
2. R = 5%, NB = $517.50
3. T= 5 YEARS, NB = $612.50
4. P= $675, NB = $783
Step-by-step explanation:
1. p= 300, r=3% t=4year
I= p*r*t
i= 300 * (3/100) * 4
i = 300 * 0.03 * 4
i = 36
New Balance = 300+36 = $336
2. r = (i*100)/(p*t)
= (67.50*100)/(450*3)
= 6750/1350
= 5%
New Balance =450+67.50 = $517.50
3. t= (i*100)/(p*r)
= (112.50*100)/(500*4.5)
= 11250/2250
=5
New Balance = 500+112.50 =$612.50
4. p= (i*100)/(r*t)
= (108*100)/(8*2)
= 10800/16
= $675
New Balance = $675+$108 = $783

The graph of y=-1/2x+2 is positive over the interval negative infinity and 4 and negative over the interval 4 and infinity. What happens on the graph when ? Explain.
Answer:
The information that we have is:
"The graph of y=-1/2x+2 is positive over the interval negative infinity and 4 and negative over the interval 4 and infinity."
Now, i guess that the question is:
"What happens on the graph when x = 4 ?"
Well, if for values of x smaller than 4 the graph is negative and for values of x larger than 4 the graph is positive, this must that the graph must cross the x-axis at some point, then with only that information, we can conclude that the graph is equal to zero when x = 4.
But we could also test it with the equation:
y = -(1/2)*x + 2
if we replace the x by a 4.
y = -(1/2)*4 + 2 = -2 + 2 = 0.
Then our previous hypothesis was correct.

Fractions: three oil tankers together contain 37 5/7 litres of oil. If two tankers have 11 3/14 litres and 12 3/7 litres of oil. Find the oil in the third tanker
Step-by-step explanation:
It is given that, three oil tankers together contain 37 5/7 litres of oil.
Total volume of oil is [tex]\dfrac{264}{7}\ L[/tex]
If two tankers have 11 3/14 litres and 12 3/7 litres of oil.
Oil in first tanker is [tex]\dfrac{157}{14}\ L[/tex]
Oil in second tanker is [tex]\dfrac{87}{7}\ L[/tex]
Oil in first and second tanker is :
[tex]\dfrac{157}{14}\ L+\dfrac{87}{7}\ L=\dfrac{331}{14}\ L[/tex]
Noo, oil in the third tanker = total volume - (Oil in first tanker + second tanker )
[tex]=\dfrac{264}{7}\ L-\dfrac{331}{14}\ L\\\\=\dfrac{197}{14}\ L[/tex]
Hence, this is the required solution.

two complementary angles have a difference of 36°. Find the measure of each angle. (Complementary angles are angles that add up to 90°) Show ur work
Answer:
27°,63°
Step-by-step explanation:
Let the two angles be a and b.
They are complementary, meaning they add up to 90. Thus:
[tex]a+b=90[/tex]
And we are told their difference is 36. Therefore:
[tex]a-b=36[/tex]
Solve for the system of equations. Add b to both sides in the second equation:
[tex]a=b+36[/tex]
Substitute this into the first:
[tex](b+36)+b=90[/tex]
Combine like terms;
[tex]2b+36=90[/tex]
Subtract 36:
[tex]2b=54[/tex]
Divide by 2:
[tex]b=27[/tex]
So, b is 27 degrees.
Use the second equation again:
[tex]a-b=36[/tex]
Now that we know b is 27, substitute:
[tex]a-27=36[/tex]
Add 27 to both sides:
[tex]a=63[/tex]
So, a is 63 degrees.
And we're done :)
Answer:
27 and 63
Step-by-step explanation:
x - y = 36
x + y = 90
add the equations together
2x = 126
x = 63
substitute x for x in the first equation
63 - y = 36
y = 27
Use the diagram below to find the value of x
{NO} =17
{NP} =5x-6
Answer : The value of 'x' is 8.
Step-by-step explanation :
As we are given that :
NO = 17
NP = 5x - 6
From the given diagram we conclude that NO and OP are equal and RO and OQ are equal. That means,
NO = OP and RO = OQ
That means,
NO = OP = 17
And we know that:
NP = NO + OP
So,
5x - 6 = 17 + 17
5x - 6 = 34
5x = 34 + 6
5x = 40
x = 8
Thus, the value of 'x' is 8.

[tex]y \ge 4x-5[/tex]
===============================================
Explanation:
First we need to find the equation of the boundary line. This is the line that separates the shaded region versus the non-shaded region.
The boundary line goes through (0,-5) so this is the y intercept, so b = -5
Another point on the boundary line is (1,-1). The slope of the line through (0,-5) and (1,-1) is m = 4. You can use the slope = rise/run idea or you could use the slope formula to get m = 4.
With m = 4 and b = -5, the y = mx+b equation updates to y = 4x-5
The boundary line has the equation y = 4x-5
Because it is a solid boundary line (instead of dashed) and the shading is above the boundary, this means we change the equal sign to "greater than or equal to"
Therefore we get [tex]y \ge 4x-5[/tex]
Note: a solid boundary line means that points on this boundary are included in the solution set. A dashed boundary line would mean you don't include boundary points in the solution set. So that's why there is a "or equal to" portion in the inequality sign.
