Answer:
x=144
Step-by-step explanation:
Step 1- Find the sum of degrees in the polygon using the equation below. n=number of sides in the polygon
(n-2)180
(8-2)180=6(180)= 1080
Step 2-Subtract the angles provided to find x
1080-129-132-136-124-141-158-116=144
The value of x in the octagon is given by the equation x = 144°
What is the sum of the interior angles of a polygon?The sum of the interior angles of a polygon is given by the formula
Sum of Interior angles of a polygon with n sides is
nθ = 180° ( n - 2 )
where n is the number of sides
θ = angle in degrees
Given data ,
Let the number of sides of the polygon be represented as n
The value of n = 8
So , the sum of the interior angles of an octagon is given by
nθ = 180° ( n - 2 )
Substituting the values in the equation , we get
nθ = 180° ( 8 - 2 )
nθ = 180° x 6
nθ = 1080°
Now , the angles in the octagon = { x , 124° , 141° , 158° , 116° , 129° , 132° , 136° }
Sum of the interior angles of an octagon A = 1080°
Substituting the values in the equation , we get
x + 124° + 141° + 158° + 116° + 129° + 132° + 136° = 1080°
x + 936° = 1080°
x = 144°
Therefore , the value of x is 144°
Hence , the value of x from the polygon is 147°

jasons cutting a 2 2/5 meter string into sections that are 3/4. how many sections can he cut
Answers
Answer:
3 1/5
Step-by-step explanation:
Okay, this is a standard division problem, so our equation is:
2 2/5 ÷ 3/4
but then we have to covert the mixed number to an improper fraction:
12/5 ÷ 3/4
do the cross thingy:
4/5 x 4/1 = 16/5 = 3 1/5
So Jason can cut 3 1/5 sections or 3 if you round

Complete the statements by filling in the blank. When constructing a confidence interval, to increase the level of confidence, you must ________ [increase/decrease] the margin of error and the confidence interval will be _________ [narrower/wider]. A larger sample size will improve the precision of the confidence interval, therefore, all things being equal, a larger sample size will result in a __________ [smaller/larger] margin of error and the confidence interval will be _________ [narrower/wider].
Answers
Answer:
Increase; wider; smaller; narrower.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
A confidence interval can be defined as a measure of the number of times that a population parameter would be within a given set of data. Thus, it is an estimate of the uncertainty of a given statistical data.
When constructing a confidence interval, to increase the level of confidence, you must increase the margin of error and the confidence interval will be wider. A larger sample size will improve the precision of the confidence interval, therefore, all things being equal, a larger sample size will result in a smaller margin of error and the confidence interval will be narrower.
Hence, for an estimator to be consistent it must have both a small bias and small variance.

Which of the following options shows the solution to the system of equations and explains why? (4 points)
a
(3, 2), because the point does not lie on any axis
b
(3, 2), because one of the lines passes through this point
c
(3, 2), because the point lies between the two axes
d
(3, 2), because both lines pass through this point
Answers
Answer:
The solution to the system of equations is (3, 2) and because both lines pass through this point.
Hence, option D is correct.
Step-by-step explanation:
Given the system of equations
Line A: y = x − 1
Line B: y = −3x + 11
Arrange equation variables for elimination
[tex]\begin{bmatrix}y-x=-1\\ y+3x=11\end{bmatrix}[/tex]
subtracting the equations
[tex]y+3x=11[/tex]
[tex]-[/tex]
[tex]\underline{y-x=-1}[/tex]
[tex]4x=12[/tex]
solving 4x = 12 for x
[tex]4x = 12[/tex]
divide both sides by 4
[tex]\frac{4x}{4}=\frac{12}{4}[/tex]
Simplify
[tex]x = 3[/tex]
For y = x − 1, substutute x = 3
y = x-1
y = 3 - 1
y = 2
Thus,
(x, y) = (3, 2)
Therefore,
The solution to the system of equations is (3, 2) and because both lines pass through this point.
Hence, option D is correct.

Step-by-step explanation:
Let the coordinate be A(3, -5) and A'(2, -3)
Using the formula for calculating the distance between two points
D = √(x2-x1)²+(y2-y1)²
AA' = √(2-3)²+(-3-(-5))²
AA' = √(-1)²+(-3+5))²

William is thinking of 2 numbers. The larger number is four less than two times the smaller
number. The sum of the numbers is 104. What are William's numbers? Please write your
answer in a sentence.
Answers
Answer:
The numbers are 36 and 68.
Step-by-step explanation:
Let the smaller number be x.
"The larger number is four less than two times the smaller
number."
The larger number is
2x - 4
The sum of the numbers is x + 2x - 4, or 3x - 4.
"The sum of the numbers is 104."
3x - 4 = 104
3x = 108
x = 36
The smaller number is 36.
The larger number is 2x - 4, or
2x - 4 = 2(36) - 4 = 72 - 4 = 68
The larger number is 68.
Answer: The numbers are 36 and 68.
