Step-by-step explanation:
The reason it has to be A is because you don't have to even thing about the standard deviation right here because the only answer that has a mean of 131 is answer A.

Find the value of the variables in each figure. Explain your reasoning.
Answer:
see explanation
Step-by-step explanation:
The figure has one pair of parallel sides and is a trapezoid.
Each lower base angle is supplementary to the upper base angle on the same side, thus
15x + 30 + 10x = 180 , that is
25x + 30 = 180 ( subtract 30 from both sides )
25x = 150 ( divide both sides by 25 )
x = 6
Also
3y + 18 + 90 = 180 , that is
3y + 108 = 180 ( subtract 108 from both sides )
3y = 72 ( divide both sides by 3 )
y = 24
-------------------------------------------------------------------
2x, 90 and x lie on a straight line and sum to 180 , thus
2x + 90 + x = 180 , that is
3x + 90 = 180 ( subtract 90 from both sides )
3x = 90 ( divide both sides by 3 )
x = 30
------------
2y and x are alternate angles and congruent , thus
2y = x = 30 ( divide both sides by 2 )
y = 15

Step-by-step explanation:
simplify 4/7 + 5/6 whoever possible
Hey there!
4/7 + 5/6
≈ 24/42 + 35/42
≈ 24 + 36/ 42 - 0
≈ 59/42
≈ 1 17/42
Therefore, your answer is:
59/42 or 1 17/42
EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE EQUIVALENT.

Answer:
B and Line HG
Step-by-step explanation:
1st One:
This one is kind of hard to explain without an image, but imagine the planes that those triangles are on went on forever. If you think about it, you'll realize that they intersect along line FG. You'll be able to learn how to do this with a little bit more practice.
2nd One:
The symbol above the HG stands for a line, because both ends go on forever. A ray would have one endpoint and one end going on forever, and a line segment would have two endpoints, so no arrows above it.

Shaun keeps his baseball card collection in an album. The album has 25 pages, and each page can hold 9 cards. Four pages are empty, and the rest are full. Write an equation that can be used to determine the number of baseball cards b in Shaun's collection.
Answer:
25x5-4=b
Step-by-step explanation:
The equation to determine the number of baseball cards in Shaun's collection is b = (25 - 4) × 9
Number of pages in the album = 25 pages
Number of empty pages = 4
Number of full pages = 25 pages - 4 pages = 21 pages.
Number of cards that each page can hold = 9 cards.
Therefore, the equation to determine the number of baseball cards in Shaun's collection will be:
b = (25 - 4) × 9
b = 21 × 9
b = 189 cards.
There are 189 cards in the collection.

What is a reflection across or over the x-axis?In Mathematics, a reflection across or over the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would either change from positive to negative or negative to positive.
This ultimately implies that, a reflection across the x-axis is given by this transformation rule: (x, y) → (x, -y).
By applying a reflection across or over the x-axis to the function, we have the following;
f(x) = -|x|
-f(x)' = |x|
f(x)' = -|x|
Next, we would translate the function to the right by 1 unit as follows;
f(x)' = -|x - 1|

It is the same distance from second base to first base, and from second base to third base. The angle formed by first base, second base, and home plate has the same measure as the angle formed by third base, second base, and home plate. What can you conclude about the distance from first base to home plate, and from home plate to third base? Explain using your knowledge of congruent triangles.
Answer:
The answer is
Converting this into a geometry problem requires us to name the points. Let give the home plate a symbol A, first base will be B, second base will be C, and the third base will be D. Now, we can present a geometrical proof:
STATEMENTS | REASONS
(1) BC = CD | Given
m(2) AC = AC | Reflexive Property
(3) triangle ACD = triangle ACB | SAS Congruence
(4) AD = AB | CPCTC
when CPCTC means Congruent Parts of Congruent Triangles are Congruent.
Therefore, the distance from first base to home plate, and from home plate to third plate are equal.

Select the correct answer from each drop-down menu. Polygon ABCD goes through a sequence of rigid transformations to form polygon A′B′C′D′. The sequence of transformations involved is a reflection across the , followed by a reflection across the line . Reset Next
Answer:
The sequence of transformations involved is a reflection across the x axis, followed by a reflection across the y = x line
Step-by-step explanation:
The polygon ABCD is shown in the image attached. The coordinates of the polygon are A(-6, 6), B(-4, 6), C(-4, 4), D(-6, 2), while the polygon A'B'C'D' is at A'(-6, -6), B'(-6, -4), C'(-4, -4), D'(-2, -6)
A transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, dilation and rotation.
If a point O(x, y) is reflected across the x axis, the new coordinate is O'(x, -y).
If a point O(x, y) is reflected across the y = x line, the new coordinate is O'(y, x)
Hence if polygon ABCD is reflected across the x axis, the new coordinates are A*(-6, -6), B*(-4, -6), C*(-4, -4), D*(-6, -2). If a reflection across the y = x line, the new coordinates are A'(-6, -6), B'(-6, -4), C'(-4, -4), D'(-2, -6)
Answer:
Polygon ABCD goes through a sequence of rigid transformations to form polygon A′B′C′D′. The sequence of transformations involved is a reflection across the y-axisy = -x, followed by a reflection across the line y = xy = -x.

All quadrilaterals have interior angles that add up to 360 degrees
The sum of all the angles in a quadrilateral, a four-sided shape is 360 degrees, so we get the equation:
[tex]x + 127 +87 + 73 = 360\\x + 287 = 360\\x = 73[/tex]

Put the following equation of a line into slope-intercept form, simplifying all fractions. 2x-3y=−9
Answer:
Step-by-step explanation:
Slope-intercept from: y = mx +c
Here, m is the slope & c is the y-intercept.
So, we have to isolate y. To isolate y first subtract 2x from both sides.
2x - 3y = -9
-3y = -2x -9
Now, divide the entire equation by the co efficient of y (-3)
[tex]\dfrac{-3}{-3}y=\dfrac{-2}{-3}x-\dfrac{9}{-3}\\\\\\y=\dfrac{2}{3}x + 3[/tex]
