Step-by-step explanation:
To find the coordinates of the midpoint of a segment, find the average of the x-coordinates of the endpoints and the average of the y-coordinates of the endpoints.
1. (1, 2) and (5, 8)
x-coordinate of midpoint = (1 + 5)/2 = 6/2 = 3
y-coordinate of midpoint = (2 + 8)/2 = 10/2 = 5
Midpoint: (3, 5)
2. (0, 1) and (1, 7)
x-coordinate of midpoint = (0 + 1)/2 = 1/2
y-coordinate of midpoint = (1 + 7)/2 = 8/2 = 4
Midpoint: (1/2, 4)

O y= √x-5
O y= √x+5
O y= √x+5
O y=√x-5
Answers
Answer: A is the correct answer .
Start with the last two choices .
You have x+ 5 and × - 5 in the square root .
A square root can never be negative .
That means that the lowest value of y can have in the last two choices is 0 .
Now range doesn't include -4.
Now look at choice B .
sqrt (x) is at least 0.
Then you add 5 .
The range doesn't include -4.
Now look at choice A .
sqrt (x) is at lest 0 .
Now ,you subract 5 .
The lowest value y can have is -5 . That includes -4.
Choice A is the answer .
y will be at least 5
Hope it works out !

Variance and standard deviation
Answers
Answer: 8.3
Step-by-step explanation:
To find the variance, you want to find the mean of the data.
[tex]\frac{3+3+8+1+9+6}{6} =5[/tex]
Now that we have the mean, we find the difference between each data point and the mean.
3-5=-2
3-5=-2
8-5=3
1-5=-4
9-5=4
6-5=1
With the difference, you square each and find the average.
(-2)²=4
(-2)²=4
3²=9
(-4)²=16
4²=16
1²=1
[tex]\frac{4+4+9+16+16+1}{6} =\frac{25}{3}[/tex]

2) Find the common difference in the arithmetic sequence, an, in which a1 = 16 and a9 = 36.
[Show all work.]
Answers
The common difference in the arithmetic sequence is 2.5
What is arithmetic sequence ?
Arithmetic sequence is a sequence in which the differences between consecutive terms are always same.
Example : 2, 5, 8, 11, ..... is an arithmetic sequence where the common difference is 3.
What is the formula of arithmetic sequence ?Formula of arithmetic sequence is [tex]a_{n} =a_{1}+(n-1)d[/tex] ,
where [tex]a_{n}[/tex]= [tex]n^{th}[/tex] term in the sequence,
[tex]a_{1}[/tex]= [tex]1^{st}[/tex] term in the sequence,
d = common difference between terms
How to find required common difference ?Given, [tex]a_{1}[/tex] = 16 and [tex]a_{9}[/tex] = 36
Let, d be the common difference.
∴ From the formula of arithmetic sequence,
[tex]a_{9} =a_{1}+(9-1)d[/tex]
⇒ 36 = 16+8d
⇒ 36-16=8d
⇒ 20=8d
⇒ d = 20/8
⇒ d = 5/2 = 2.5
Hence, The common difference is 2.5

The value of x and y angles on the given lines are x=35 degrees and y=125 degrees.
What is a straight line?A line is a collection of points which joins the two points on the surface.
How to calculate an angle?If we consider the angles which are linear pair, we found that
55 +y=180 because they are on a straight line.
From the figure wee found that x+55+90=180 because they are on a straight line.
solving the second equation we will get , x=180-145=35
solving the first equation we will get , y=180-55=125.
Hence the value of x angle is 35 degrees and the value of y angle is 125 degrees.

Determine the length of the arc that subtends an angle of 2.8 radians at the centre of a circle with a radius 12cm.
A. 13.3 cm
B. 33.6 cm
C. 16.8 cm
D. 148.0 cm
Answers
Answer:
B. 33.6 cm
Step-by-step explanation:
To find determine the length of an arc that subtends an angle of 2.8 radians at the centre of a circle with radius 12 cm, we will follow the steps below;
First write down the formula for calculating length of an arc
If the angle is measured in degree, then the formula for calculating the length of an arc is :
length of an arc = Ф/360 × 2πr
but if the angle is measured in radians, then the formula for calculating length of an arc will be:
length of an arc = r Ф
where r is the radius and Ф is the central angle in radians
In the case of the question given to us, the angle is given in radians, so we will use the second formula
angle Ф = 2.8
radius = 12 cm
length of an arc = r Ф
=12 × 2.8
=33.6
Length of the arc = 33.6 cm

One supplementary angle is 15 degrees less than twice the other. Find the measure of the two supplementary angles.
Answers
Hey there!
To find our answer, we need to set up a system of equations. Remember, supplementary angles equal 180 degrees when combined. We will call one of our angles A and the other one B. Let's set it up below! :)
A=2B-15 (one angle is 15 degrees less than twice the other)
A+B=180
We need to find one of our variables. To do this, we only put one variable in the equation. But how, there are two variables in both equations! Well, as you can see, we see the A is equal to 2B-15, so we can take 2B-15 and put it into the second equation in place of A because it is equal to A, and then we will only have Bs and we can solve for it. This method is known as solving systems of equations with substitution.
Let's solve with substitution!
2B-15+B=180
3B-15=180 We combine our Bs.
3B=195 We add 15 to both sides.
B= 65 We divide both sides by three.
Now, we need to find what A is, but this will be really easy to do! If you remember, our angles are supplementary, so when you combine them, we will get 180, as you can see in our second equation in our first system of equations. So, we simply subtract 65 from 180.
180-65=115
Our two angles are 65° and 115°.
We can also check this with the original problem.
If you double 65, we have 130. Then, if we subtract 15, we have 115. Systems of equations are a pretty awesome way to figure this out!
I hope this helps! Have a great day!

x - 2 (x - [tex]\frac{3x}{2}[/tex]) = 2 (4 - x) + 10
x − 2 × [tex]\frac{-x}{2}[/tex] =2(4−x)+10

Express 0.31 as a percent.
Answers
Answer: 31%
Step-by-step explanation: We can change a decimal to a percent by moving the decimal point two places to the right.
So in this problem, to change 0.31 to a percent, we
move the decimal point two places to the right.
So we have 31%.
So 0.31 can be written as 31%.
This should make sense because 0.31 can be read
as 31 hundredths or 31 over 100 which is 31%
Answer:
31%
Step-by-step explanation:
To change 0.31 into a percent, you must move the decimal to the right two times.
When we move the decimal in 0.31, it will look like this:
03.1
Now, if we move the decimal again, it will look like this but will be equivalent to 31%:
031. = 31%
Another step-by-step explanation:
You can also write 0.31 as a fraction which is:
31/100 = 31%
It will still be equal to 31%.
Therefore, 0.31 as a percent is equal to 31%.
Hope this helps!

Answers
Answer:
I need more information
Step-by-step explanation:
Answer:
z = 4°
Solution:
Given EFGH is an isosceles trapezoid.
By the property of isosceles trapezoid, non-parallel sides are congruent.
⇒ GH = EF
Angles opposite to equal sides are congruent.
∠H ≅ ∠G
m∠H = m∠G
105° = 3z + 93°
Subtract 93° from both sides, we get
12° = 3z
Divide by 3 on both sides, we get
4° = z
Switch the sides.
z = 4°
Hence the value of x is 4°.
