The initial amount of stickers given to each of the volunteers was 4 stickers while the final amount given to each of them was 6 stickers.
How to solve Algebra Word problems?We are told that Mai gave each of the five volunteers the same number of stickers. Thereafter, she gave each of them 2 stickers each and the total was 30 stickers.
If the initial amount given to them each was y, then we have;
5(y + 2) = 30
y + 2 = 6
y = 6 - 2
y = 4
Thus, we can say that the amount of stickers she gave each of them initially was 4 stickers while the amount she gave them in total after the extra ones was 6 each

How do you convert raw score to LSAT?
Answers
Answer: The conversion of a raw score to a scaled LSAT score is a complex process that involves several steps. The Law School Admission Test (LSAT) is a standardized test used by law schools in the United States and Canada to assess applicants' critical thinking, reading comprehension, and analytical reasoning skills.
Here's a general overview of the process of converting a raw score to a scaled LSAT score:
- Raw score calculation: The raw score is the number of questions answered correctly on the LSAT. There is no penalty for incorrect answers, so it is in your best interest to answer every question, even if you are unsure of the correct answer.
- Equating: The LSAT is equated to account for differences in difficulty between test forms. This means that the raw scores of test-takers are adjusted so that the scaled scores are consistent across different test forms.
- Scaling: The raw scores are then scaled to a range of 120 to 180, with a median score of 150 and a standard deviation of 10. This scaling process allows for meaningful comparisons between test-takers, regardless of the difficulty of the specific test form they took.
It is important to note that the LSAT score is not based solely on the number of questions answered correctly, but also on the difficulty of the questions. This means that a high raw score on a particularly difficult test form may result in a lower scaled score than a lower raw score on a less difficult test form.

If x is a continuous random variable then P(x≥A)=
A. P(X
B. 1-P(X>A)
C. P(X>A)
D. 1-P(X
Answers
If x is a continuous random variable then P(x≥A) = P(X>A). So, the correct option is C, i.e., P(X>A).
For a continuous random variable, the probability of X taking any specific value is zero, since there are infinitely many possible values that X could take. Instead, we calculate the probability that X falls within a certain range of values.
To find the probability that X is greater than or equal to A, we can use the cumulative distribution function (CDF) of X, denoted as F(X). The CDF F(X) gives the probability that X is less than or equal to a certain value x, i.e., F(X) = P(X ≤ x).
Now, since the event X ≥ A is the complement of the event X < A, we can use the complement rule to write:
P(X ≥ A) = 1 - P(X < A)
Using the definition of CDF, we get:
P(X ≥ A) = 1 - F(A)
Therefore, the probability of a continuous random variable X being greater than or equal to a certain value A is P(X>A) = 1 - F(A). This is the correct option C in the given question.

Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).
Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)
Answers
The coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis include the following:
P" = (-4, 0).
Q" = (-(3), 1) = (-3, 1).
R" = (1, -2).
What is a reflection?In Geometry, a reflection over the y-axis (y = x) is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, a reflection over the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.
By applying a reflection over the y-axis to the coordinates of triangle P′Q′R′, the coordinates of triangle P′′Q′′R′′ include the following:
(x, y) → (-x, y)
Coordinate P' = (4, 0) → Coordinate P" = (-(4), 0) = (-4, 0).
Coordinate Q' = (3, 1) → Coordinate Q" = (-(3), 1) = (-3, 1).
Coordinate R' = (-1, -2) → Coordinate R" = (-(-1), (-2)) = (1, -2).

largest angle.
Answers
Answer:
90 degrees
Step-by-step explanation:
10 + 3 + 7 = 20
10/20 x 180 = 90 degrees
Hope this helped :)
Answer:
The largest angle is 90 degree[10]
Step-by-step explanation:
Let 10:3:7 be x
10x+3x+7x = 180 [ angle sum property of a triangle ]
20x = 180
x=180/20
=9/1
=9
10x=10*9=90
3x=3*9=27
7x=7*9=63
90>63>27
therefore the largest angle is 90 degree.

In a triangle ABC, AB=AC. If D is the mid-point of the side BC, prove that:
i) AD is perpendicular to BC.
ii) AD bisects angle BAC
Answers
Answer:
Step-by-step explanation:
Given: In triangle ABC, AB = AC and D is the midpoint of BC.
To prove:
i) AD is perpendicular to BC.
We can prove this by using the midpoint theorem, which states that a line segment connecting the midpoints of two sides of a triangle is perpendicular to the third side and half as long as the third side.
Since D is the midpoint of BC, we have BD = DC. Thus, the line segment AD connects the midpoints of sides AB and AC of triangle ABC.
By the midpoint theorem, AD is perpendicular to BC and AD = BC / 2.
ii) AD bisects angle BAC
We can prove this by using the fact that if two line segments are perpendicular and one is an altitude of a triangle, then the two line segments divide the triangle into four smaller triangles that are congruent by SAS congruence.
Since AD is perpendicular to BC, we have two right triangles, ABD and ACD. By the Pythagorean theorem, we have AB = AC, which means that ABD and ACD are congruent by SAS congruence.
Since ABD and ACD are congruent, we have angle BAD = angle CAD. Also, since angle BAC is the sum of angles BAD and CAD, we have angle BAC = 2 * angle BAD.
Therefore, by substitution, we have angle BAC = 2 * angle CAD. This means that angle CAD is half of angle BAC, or in other words, AD bisects angle BAC.
Hence, we have proved that in triangle ABC, AD is perpendicular to BC and AD bisects angle BAC.

Answers
x^2 + (y – 3)^2 = 36
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
If the center lies on the y-axis, then h = 0: (x - 0)^2 + (y - k)^2 = r^2
If the circle diameter is 12, then the circle radius is 6, and so r^2 = 36
So, among the given equations, your

What is the formation of fossil fuels?Fossil fuels are gotten from the decomposition of plants and animals. These fuels, which can be found in the Earth's crust and contain carbon and hydrogen, can be burned for energy. Fossil fuels include coal, oil, and natural gas.
Coal is a material that is typically found in sedimentary rock deposits where layers of rock and dead plant and animal matter are piled up. More than half of the weight of a piece of coal must come from fossilized plants. Oil was discovered as a solid material between layers of sedimentary rock, such as shale.

The angles Θ are:
Θ = 45°
Θ = 225°
If tan = 1, the angle can be found by taking the inverse tangent (or arctan) of 1.
Because tangent is positive in the first and third quadrants, we must examine angles ranging from 0° to 360° that fall within those quadrants:
We have the following in the first quadrant:
arctan(1) = 45° if tan = 1
We have the following in the third quadrant:
225° = tan = 1 + 180° = arctan(1)
As a result, the possible angles for are 45° and 225°, which satisfy the equation tan = 1.

In the triangle ΔJKL, the length of side k found using the law of cosines is approximately 1764 inches.
What is meant by the law of cosines?
The law of cosines, commonly referred to as the cosine formula or cosine rule, is a relation in trigonometry that links the lengths of a triangle's sides to the cosine of one of its angles. It claims that we can determine the length of the third side of a triangle if we know the length of the first two sides and the angle between them.
If ABC is a triangle, then as per the statement of cosine law, we have:
c = [tex]\sqrt{a^{2}+b^{2}-2 a b \cdot \cos \gamma}[/tex]
where,
c = length of side c
a = length of side a
b = length of side b
γ = angle opposite c
Given a triangle, ΔJKL
The length of side l= 920 inches
The length of side j = 880 inches
∠K = 157°
According to the law of cosines,
k² = l² + j² - 2.l.j . cos K
= 920² + 880² - 2 * 920 * 880 * cos (157°)
= 846400+ 774400 - (-1490481.46)
