The image shows parallel lines cut by a transversal. The expressions represent unknown angle measurements. What is the value of x?
A)5 B)7 C)9 D)11
Answer: C
because
it is
Answer:
Step-by-step explanation:
the answer is B cause a Supplementary angles sum is 180°. So, set the angles equal to 180° and solve for x.
11x + 8 + 12x + 11 = 180
23x + 19 = 180
23x = 161
x = 7

Given
below, is PQ a minor arc, a major arc, or a semicircle?
A. Minor arc
B. Semicircle C. Major arc
Answer:
B. Semicircle
Step-by-step explanation:
Semicircle means "half of a circle"
A minor arc is when the arc has a degree of less than 180°
A major arc is when the arc has a degree of more than 180°
If the degree is exactly 180°, then it's a semicircle. And it tells you the degree, which is 180°
Answer:
Semicircle

what is a compound inequality that represents all real numbers that are greater than -8 but less than 8
Answer:
The inequality is "-8 < x < 8" that can also be expressed as x > - 8 and x < 8
Step-by-step explanation:
In this case there are two inequalities. The first one is for all real numbers that are greater than -8. In this case we will represent the real numbers as "x" and this inequality can be represented as:
x > - 8
The second inequality is for all real numbers that are less than 8, this can be represented as:
x < 8
To create the compound inequality we have two use both of the inqualities above:
-8 < x < 8
x > - 8 and x < 8
In this case we use and because the real number must satisfy both inequalities at the same time.
A population has a standard deviation of 5.5. What is the standard error of
the sampling distribution if the sample size is 49? Round your answer to two
decimal places.
Answer:
The standard error of the sampling distribution is [tex]\sigma_x = .79[/tex].
Step-by-step explanation:
We can find the standard error of the sampling distribution using this formula:
The standard deviation of the sampling distribution, also known as the standard error, can be found by taking the population standard deviation and dividing it by the square root of the sample size, both of which we are given in the problem.
[tex]\displaystyle \sigma_x = \frac{5.5}{\sqrt{49 }} = .7857[/tex]Rounded to two decimal places: [tex]\sigma_x = .79[/tex]
The standard error of the sampling distribution if the sample size n = 49 and the population standard deviation σ = 5.5 is .79.

Does the graph f(x)=-2x^2 -1 have a maximum or a minimum? Explain.
Answer:
It has a maximum
Step-by-step explanation:
The way I think about it is looking at "a" (the leading variable's coefficient, so __x²), if it's negative, the graph is a frown, but if it's positive, it's a smile. In this case, a is -2, so the graph would have the shape of a frown, which has a maximum.
I hope this helped!

Alternate interior angles are equal.
6x - 2 = 46
6x = 46 +2
6x = 48
x = 48/6
x = 8
Answer:
8
Step-by-step explanation:
When you have a line intersecting parallel lines, the opposite interior angles are always the same.
46 + 2 = 48
48 / 6 = 8
Suppose a bag contains 5 balls numbered 1 through 5. In how many way scan you select 5 balls from the bag if there is no replacement after selection?
Answer:
5
Step-by-step explanation:
We are being asked in how many ways an enumerated ball can be removed without any type of replacement, therefore it would be a combination without repetition:
nCr = n! / r! * (n-r)!
n, total number of balls, 5
r, specific number of balls, 1
5C1 = 5! / (1! * 4!) = 5
Therefore there are 5 ways to do the above.

What is the volume of a 3 foot tall cylindrical trash can with a 1 foot radius
The volume of the cylindrical trash can with a 1 foot radius and 3 foot height is 9.426 cubic feet.
Explanation:The volume of a 3-foot tall cylindrical trash can with a 1-foot radius can be calculated using the formula V = πr²h, where r is the radius and h is the height.
Given that the radius is 1 foot and the height is 3 feet, we can substitute these values into the formula:
V = 3.142 × (1 foot)² × 3 feet = 9.426 cubic feet
Therefore, the volume of the trash can is 9.426 cubic feet.

In the Three-Dimensional Figures and Cross Sections section, what is the difference between a prism and a pyramid? *
Answer:
A prism has two identical bases that are parallel. A pyramid has one base. A prism or pyramid is named for the shape of its base.
Final answer:
The primary difference between a prism and a pyramid is their base shapes, the number of vertices, edges, and faces, with prisms having parallel and congruent bases while pyramids have triangular faces that meet at an apex.
Explanation:
The main difference between a prism and a pyramid lies in the shapes of their bases and the number of faces, edges, and vertices. A prism is a polyhedron that has two parallel and congruent faces called bases that are polygons of the same shape and size, and the other faces, known as lateral faces, are parallelograms resulting from connecting the corresponding vertices of the two bases. In contrast, a pyramid has a polygonal base and triangular faces that connect the base to a single point called the apex. A prism has as many lateral faces as the sides of its base, while a pyramid has as many triangular faces as the sides of the base polygon. Another way to distinguish them is by their vertices and edges; a prism will always have twice as many vertices and edges in the sides of the bases than a pyramid with the same shaped base.

Find the sum -6/3 - (-7/15)
Answer:
-1 [tex]\frac{8}{15}[/tex]
Step-by-step explanation:
That's the answer I think
Answer:
- 23/15 or - 1 8/15
Step-by-step explanation:
When you want to subtract fractions, you first want to see if they have the same denominator. In this case, there isn't a common denominator so we need to make it so there is. Since 15 is the larger one and a multiple of 3, we can change -6/3 to -30/15 by multiplying the top and bottom by 5. Now the double negatives cancel each other out so instead of -30/15 - (-7/15), it will be -30/15 + 7/15. Add them together and you get -23/15.

Which statement is true about the data set 4, 5, 6, 6, 7, 9, 12
Answers:
A: mean=mode
B: mode=median
C: mean < median
D: mode > mean
Answer:
b
Step-by-step explanation:
Because there are two sixes so that is the mode and the middle is 6 so that would be the middle and both of them are six so the answer would be B
The mode and the median have the same value which is 6. Therefore, option B is the correct answer.
The given data set is 4, 5, 6, 6, 7, 9, 12.
What is the mode?The mode is the value that appears most frequently in a data set. A set of data may have one mode, more than one mode, or no mode at all.
The mode of the given data is 6.
Median: The median is the middle number in a sorted, ascending or descending list of numbers and can be more descriptive of that data set than the average.
The median of the given data is 6.
Mean = (4+5+6+6+7+9+12)/7
=49/7 = 7
Here, the mode and the median have the same value which is 6. Therefore, option B is the correct answer.

Is u = - 1/2 a solution of 8u - 1 = 6u
Answer:
-1/2 is not a solution
Step-by-step explanation:
8u-1 = 6u
Subtract 8u from each side
8u-1 -8u = 6u-8u
-1 = -2u
Divide each side by -2
-1 /-2 = -2u/-2
1/2 = u
Answer:
No, u = - 1/2 is not a solution of 8u - 1 = 6u
Step-by-step explanation:
[tex]8u - 1 = 6u \\ 8u - 6u = 1 \\ 2u = 1 \\ \\ u = \frac{1}{2} [/tex]
here we get u = +1/2
