Based on these results, express the probability that an eighth grader chosen at

What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
Probability = (Number of possible outcomes)/(Total number of outcomes)
Total number of outcomes = 2 + 15 + 2 + 11 = 30
Number of possible outcomes = 2
Probability = 2/30 = 1/15 = 0.0666
Percent to the nearest whole number = 0.0666 *100 = 7%

in the figure below measaure of angle 1 is 36. find angle 2,3, and 4
X/5= -2 in one step?
Answer:
To solve the equation X/5 = -2 in one step, we can multiply both sides of the equation by 5 to isolate the variable X. This gives us the equation X = -2 * 5 = -10. Therefore, the value of X that satisfies the equation X/5 = -2 is X = -10.

In the diagram, b || c. Find the value of y
Using the corresponding angle theorem, the value of y is 36 degree.
In the given question, b||c.
We have to find the value of y.
Given: b||c
Find: Value of y
Let x be the value of side angle of (2y+34) degree.
So, using the corresponding angle theorem
x = 74 degree
As we know that the sum of straight line is 180 degree.
So 2y+34+x = 180
Now putting the value of x
2y+34+74=180
After simplifying
2y+108=180
Subtract 108 on both side, we get
2y=72
Divide by 2 on both side, we get
y=36
Hence, the value of y is 36 degree.

What is meant by right triangles?If one of the triangle's angles is 90 degrees, the triangle is said to be right-angled. 90 degrees is the sum of the other two angles. Perpendicular and the triangle's base make up the sides that the right angle is formed from. The hypotenuse, or third side, is the longest of the three. It is also known as the hypotenuse.

8) Micaela and Sumalee each improved their yards by planting hostas and shrubs. They bought their
supplies from the same store. Micaela spent $33 on 3 hostas and 6 shrubs. Sumalee spent $42 on 6
hostas and 6 shrubs. What is the cost of one hosta and the cost of one shrub?
Cost of shrub is $4 and Cost of hosta is $3. Cost is the value of money that was spent on producing or providing a service and is therefore no longer available for use.
How to calculate cost ?The term "cost" can refer to the amount of money or other resources that are required to produce, acquire, or obtain something. In business and economics, cost is often used to refer to the total expense associated with a product or service, including materials, labor, and other expenses.
Micaela spent a total of $33 on 3 hostas and 6 shrubs. Since the cost of the hostas is H x 3 and the cost of the shrubs is S x 6, we can write the following equation:
H * 3 + S * 6 = 33
Similarly, Sumalee spent a total of $42 on 6 hostas and 6 shrubs, so we can write the following equation:
H * 6 + S * 6 = 42
cost 3 hostas and 6 shrubs = $33
cost 6 hostas and 6 shrubs = $42
Cost difference 33 - 42 = 9
So, cost of 3 hostas = $9
Cost of one hosta = $9/3 = $3
$9 + cost of 6 shrubs = $33
cost of 6 shrubs = $33- $9 = $24
Cost of one shrub = $24/6 = $4
Cost of shrub is $4 and Cost of hosta is $3.

I have finished half of this problem but i am still unsure on how to finish.
Answer:
Triangle PQR maps onto triangle KLM. This is possible because △PQR ≅ △KLM by ASA, and one congruent figure can be mapped onto another using rigid motions.
Step-by-step explanation:
For the first blank, we are given congruence statements for 1 side on each triangle and their two adjacent angles. This means we can use the Angle-Side-Angle theorem to declare △PQR and △KLM congruent.
For the second blank, we know that rigid transformations do not change the figure, they simply move its position on a plane, so this is the correct answer; had the △PQR and △KLM not been congruent, a non-rigid transformation would have to have occured, but this is not the case here.
Answer:
ASArigidStep-by-step explanation:
Given triangles PQR and KLM with QR ≅ LM, ∠Q ≅ ∠L, and ∠R ≅ ∠M, you want to know the applicable congruence postulate and whether the triangles are mapped to each other by rigid or non-rigid motion.
Sides and anglesThe segment QR has angle Q at one end and angle R at the other end. That means the side lies between the two angles. Likewise, segment LM lies between angles L and M.
When claiming congruence of these triangles, the appropriate postulate is the one that refers to the geometry with the congruent side between the congruent angles: ASA.
Motion"Rigid" motion is motion that preserves angle and length measures. By contrast, "non-rigid" motion may involve stretching or compression in one or more directions. It may or may not preserve angles or lengths.
Congruence is about showing that angles and lengths are the same from one figure to another. If you want to map congruent figures to each other, you must do so using rigid motion.

Approximate √/46 to the tenths place.
Answer:
To approximate the square root of 46 to the tenths place, we need to find the two-digit number that is closest to the square root of 46. Since the square root of 46 is between 6 and 7, we can estimate that it is about 6.5. We can check this estimate by finding the square of 6.5, which is 42.25. This is close to 46, but it is still a little bit lower than 46, so we can estimate that the square root of 46 is slightly larger than 6.5. Therefore, an approximation of the square root of 46 to the tenths place is 6.6.

The expression for the nth term is aₙ = 37+6n
What is an arithmetic sequence?An arithmetic sequence is a type of sequence in which the difference between the successive and preceding term is constant.
Given that, The 9th term of an arithmetic sequence is -5 and the 15th term is 31
The formula for nth term is given by;
aₙ = a+(n-1)xd
Where, a is the first term
n = number of terms
d = common difference
a₉ = a+(9-1)xd
a+8d = -5.......(i)
And
a₁₅ = a+(15-1)xd
a+14d = 31........(ii)
Solving the equation, we get,
d = 6
Putting, d = 6 in eq(i)
a+8x6 = -5
a = -5+48
a = 43
Now solving for nth term,
aₙ = 43+(n-1)x6
aₙ = 43+6n-6
aₙ = 37+6n
