Answer:
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.
Step-by-step explanation:
So basically its the part of a line that connects two points.

The mean of four numbers is 25. Three of the four numbers are 20, 26, and 26. What is the fourth number?
Answer:
28 hope this helped
Step-by-step explanation:
20+26+26=72
72+28=100
100/4=25
let the number be X
20 + 26 + 26 + X /4 = 25
72 + X /4 = 25
cross multiply
72 + X = 25*4
72 + X = 100
X = 100.- 72 = 28
X = 28
proof
20 + 26 + 26 +28 / 5 = 25

Solve for k. Describe the steps taken to find the solution.
8 + 10 - 6k = 6(4 - k)
Answer:
no solutions
Step-by-step explanation:
8 + 10 - 6k = 6(4 - k)
Distribute
8 + 10 - 6k = 24 -6k
Combine like terms
18 -6k = 24 -6k
Add 6k to each side
18 - 6k +6k = 24 - 6k+6k
18 = 24
This is never true so there are no solutions
Hey there! I'm happy to help you out!
To solve for k, we have to isolate it on one side of the equation and put all the constants on the other side.
The first thing we need to do is get the k on the right side out of parentheses. To do this, we will use the distributive property!
8+10-6k=24-6k
Now, we will combine like terms.
18-6k=24-6k
We want to get all the ks on the left side and all the constants on the right. Let's add six k to both sides to cancel out the -6k on the right.
18=24
As you can see, our variables canceled out. This is because our equation was saying 18 minus six of something was equal to 24 minus six of something, which makes no sense because that doesn't work!
We are left with 18=24, which isn't even a true equation! Therefore, there is no solution to this equation.
I hope that this helps! Have a wonderful day!
When Sophia runs the 400 meter dash, her finishing times are normally distributed with a mean of 75 seconds and a standard deviation of 1.1 second. What probability of races will her finishing time be between 74.2 and 76.4 seconds?
Round to the hundredths place (2 places after the decimal)
Answer: 90% of the time.
Step-by-step explanation: This is because you can add the two different times and the standard time of 75 seconds, divide it all by 3 leaving you with 75.2 and that is 0.2 away from the original between those times all together. Take that 0.2 and subtract it from the 1.1 deviation and you’ll get 0.9 times that by 100 and you get it in a percentage; 90%.

Which equation could be solved using this application of the quadratic formula?
A. -2x2 − 8 = 10x − 3
B. 3x2 − 8x − 10 = 4
C. 3x2 + 8x − 10 = -8
D. -2x2 + 8x − 3 = 4
Answer:
3x^2 +8x -10=-8
Step-by-step explanation:
A quadratic equation is
ax^2 + bx +c=0
has a formula
-b ± sqrt( b^2 -4ac)
--------------------------
2a
We know a = 3 b = 8 and c = -2
3x^2 +8x -2=0
Subtract 8 from each side
3x^2 +8x -2 -8=0-8
3x^2 +8x -10=-8
That is choice C
Answer:
C.
Step-by-step explanation:
Consider equation C:
3x^2 + 8x - 10 = -8
3x^2 + 8x - 2 = 0
Here a = 3, b = 8 and c = -2
Applying the quadratic formula:
x = [-b +/- √(b^2 - 4ac)] / 2a
x = [-8 +/- √(4(3)(-2)] / 2(3)
- which is the one in the question.
So it is equation C.

In one school, a half of all students who like math like science as well. Also, in that school, a third of all students who like science also like math.
b)
In that school, what is the ratio of the number of students who like math to the number of students who like science?
Answer: Is there a total for how many kids like each? If there isn't than this is how I would solve it. For percentage purposes let's say there are 100 students. 50 like math, 50 like science. Half of the students who like math also like science, which means 75 percent of the school likes science. A third of students who like science also like math, and since 75 percent of the school of 100 children likes science, that would mean 1/3 of that is 25, which would mean 75 percentof all students like math. Hence the ratio, I believe, is 1 to 1.

If cot x = -4/3 find csc x, if 270°<x<360"
Answer:
csc x = - [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
Using the trigonometric identity
csc²x = 1 + cot²x
= 1 + (- [tex]\frac{4}{3}[/tex] )² = 1 + [tex]\frac{16}{9}[/tex] = [tex]\frac{25}{9}[/tex], thus
csc x = ± [tex]\sqrt{\frac{25}{9} }[/tex] = ± [tex]\frac{5}{3}[/tex]
Since 270° < x < 360° where csc x < 0 , then
csc x = - [tex]\frac{5}{3}[/tex]

O x2(x + 1)(2x - 3)
O2(x2 - 1)(2x + 3)
Answer:
the answer is O 2x (x2-1)(2x+ 3)
Answer:
The correct answer is 2x^2(x^2 + 1)(2x - 3)
Step-by-step explanation:
First, you would factor out a single factor out of all of them, which is 2x^2. So, you would have 2x^2 (2x^3 - 3x^2 + 2x - 3) Then, you would use double grouping. When you have double grouped, you will have x^2(2x-3) and 1(2x-3) for the factors. The final factors for that is (x^2 + 1) and (2x - 3), then you would just put 2x^2 in the front to give you the final factorization and the correct answer stated at the top.

Answer:
ZY = 14, SQ= 28
Step-by-step explanation:
Because of "ZR=ZS" and "YR=YQ", so we can apply the Thales theorem:
[tex]\frac{x+2}{3x-8}=\frac{RZ}{RS} =\frac{1}{2} \\[/tex]
so 2(x+2)= 3x-8
2x+4 = 3x-8
2x-3x= -8 -4
-x = -12
or x =12
ZY = x+ 2 = 12+ 2 = 14
SQ= 2*ZY= 2*14 = 28

Solve the following system by substitution.
{
y = x2 + 6x + 10
y = -X+4
Select the correct choice and fill in any answer
- the solution(s) is/are :
- there is no solution
Answer:
(- 6, 10 ) and (- 1, 5 )
Step-by-step explanation:
Given the 2 equations
y = x² + 6x + 10 → (1)
y = - x + 4 → (2)
Substitute y = x² + 6x + 10 into (2)
x² + 6x + 10 = - x + 4 ( subtract - x + 4 from both sides )
x² + 7x + 6 = 0 ← in standard form
(x + 1)(x + 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x + 6 = 0 ⇒ x = - 6
Equate these values into (2) for corresponding values of y
x = - 1 : y = - (- 1) + 4 = 1 + 4 = 5 ⇒ (- 1, 5 )
x = - 6 : y = - (- 6) + 4 = 6 + 4 = 10 ⇒ (- 6, 10 )
What is the slope of the line that passes through the points (4, 10) and (1, 10)?
Write your answer in simplest form
Answer:
The slope will be 0
Step-by-step explanation:
Once you do the slope formula which is y2 - y1 over x2-x1
You will get 0/3 in this case. So if the numerator is a 0 the slope will also be 0.
The slope of the a straight line is given by the ratio of the Rise to the Run
of the line. The rise between the given points is zero.
The slope of the line that passes through the points (4, 10) and (1, 10) is zero.
Reason:
The given points are; (4, 10) and (1, 10)
The slope of a line, m, is given by the following formula;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where;
(x₁, y₁) = (4, 10) and (x₂. y₂) = (1, 10), we get;
[tex]Slope, \, m =\dfrac{10-10}{1-4} = 0[/tex]
The slope of the line that passes through the points (4, 10) and (1, 10) is 0.
