What is the arithmetic operation?
The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.
the product of three consecutive positive integers is 8 times thier sum.
So if 1st number is x
So the sum will be x+x+1+x+2 = 3x+3
and multiply will be x(x+1)(x+2)
according to question x(x+1)(x+2) = 24(x+1)
x³+3x²+2x = 24x+24
x = 6
So all the numbers will be 6,7 and 8
Hence the sum of their square is 36+49+64= 149

The linear function that represents the graph of that has the points on the table is: A. .f(x) = 32(3x - 1).
What are the Points of a Linear Function Graph?If a point is on a graph of a linear function, its coordinates will make the equation of the linear function true, if plugged into the equation.
Given the table that represents some of the points that are on a linear function graph, use one point, (1, 64), to check which of the functions represents the table.
Substitute x = 1 and .f(x) = 64 into each of the functions given to see which is true:
.f(x) = 32(3x - 1)
64 = 32(3(1) - 1)
64 = 32(3 - 1)
64 = 32(2)
64 = 64 [true]
.f(x) = -32(x - 3)
64 = -32(1 - 3)
64 = 64 [true], however, if we use another set of values, say (5, 448), this function will not be true.
.f(x) = -2(32x - 3)
6 = -2(32(1) - 3)
6 = -2(29)
64 = -58 [not true]
.f(x) = 16(2x - 1)
64 = 16(2(1) - 1)
64 = 16(1)
64 = 16 [not true]
Therefore, the function that represents the table is: A. .f(x) = 32(3x - 1).

HOW THE HECK AM I SUPPOSED TO USE X AND Y ON A COORDINATE GRID THAT HAS THE PROPORTIONS OF M=24R
Answer:
To use coordinates on a coordinate grid, you first need to determine the scale of the grid, which is represented by the proportion M=24R. This means that for every 24 units on the grid, the corresponding real-world distance is equal to R units.
Once you have determined the scale of the grid, you can use the coordinates to locate points on the grid. To do this, you will need to know the coordinates of at least one point on the grid, which is known as the origin. The origin is typically represented by the coordinates (0,0).
To find the coordinates of a point on the grid, you can use the following steps:
Locate the point on the grid that you want to find the coordinates for.Measure the distance from the point to the origin, using the grid scale as a guide. This distance is the point's x-coordinate.Measure the distance from the point to the y-axis, using the grid scale as a guide. This distance is the point's y-coordinate.The coordinates of the point will be a pair of numbers in the form (x, y), where x is the point's x-coordinate and y is the point's y-coordinate.
For example, if you wanted to find the coordinates of a point that is 5 units to the right of the origin and 3 units above the y-axis, the coordinates of the point would be (5, 3).
Which theorem proves that the triangles are congruent a asab Sasc SSAD SSS?
The theorem that proves that the triangles are congruent is the Side-Side-Side (SSS) Congruence Theorem.
The Side-Side-Side (SSS) Congruence Theorem states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent. This theorem is useful for proving that two triangles are congruent without having to use angles. The SSS Congruence Theorem is a useful tool for solving geometry problems involving triangles. It can be used to find the unknown side length of a triangle given the lengths of the other two sides, or in more complicated proofs involving multiple triangles. This theorem is also helpful in determining the area of a triangle, as the area is proportional to the product of the lengths of the sides.

The probability that the coin will land heads up on the first flip, tails up on the second flip, and tails up on the third flip is (1/8).
What is the probability of getting a head in a single coin toss?If we toss a coin, we have two possible outcomes: head or tail. Now:
P(E) = Favourable outcomes / Total outcomes
= 1/2
As per the question, we need heads on the first throw and tails on the next two throws. We know that for independent events:
P(A∩B∩C) = P(A)*P(B)*P(C)
Let A be the event of getting head on the first throw and B and C be events of getting tails on the second and third throws of dice respectively.
P(A) = P(B) = P(C) = 1/2
So, P(A∩B∩C) = (1/2)*(1/2)*(1/2) = 1/8

Mean (μ)=500
standard deviation(σ)=100
The probability that scores lies between 400 and 600 i.e, P(400
For the standard normal distribution curve
Z=(x-μ)/σ

−2x+5y=−2
4x−10y=4
Solution:
After solving the system of equation we will get
x = 5y/2 +1
y = 2/5- 2x/5
First equation is written
−2x+5y=−2
Subtract 5y from both sides.
−2x =−2−5y
The equation is in standard form.
−2x=−5y−2
Divide both sides by −2.
-2x/-2 = -5y-2/ -2
Dividing by −2 undoes the multiplication by −2.
x= −5y-2/-2
Divide −2−5y by −2.
so
x= 5y/2 + 1
Now the second equation is
4x−10y=4
Add 4x to both sides
-10y = 4-4x
The equation is in standard form.
Divide both sides by 10
-10y/10= 4-4x/10
Dividing by 10 undoes the multiplication by 10.
y= 4-4x/10
Divide 4-4x by 10.

The correct equations are 2x +3y=100 and x+y=48. These equations can be used to find the number of multiple-choice and free response questions on the test. The first equation, 2x +3y=100, shows that the total number of points for the multiple-choice questions (2x) plus the total number of points for the free response questions (3y) equals 100. The second equation, x+y=48, shows that the total number of multiple-choice and free response questions on the test is equal to 48. These equations can be solved simultaneously to find the values of x and y.
What is the equation of the line which passes thru 1/3 and 2 5?
y = 3x – 2 is the equation of the line which passes through 1/3 and 2 5 with slope.
We can use the slope-intercept form of the equation of a line, which is y = mx + b, where m is the slope and b is the y-intercept. We know one point on the line, which is (1/3, 2.5). We can calculate the slope by calculating the rise (change in y) divided by the run (change in x), which is (2.5 - 0) / (1/3 - 0) = 2.5 / 0.33 = 7.5. Therefore, the equation of the line is y = 7.5x + b. To solve for b, we can substitute in our point, (1/3, 2.5) into the equation. We get 2.5 = 7.5(1/3) + b, or 2.5 = 2.5 + b. Therefore, b = 0, and the equation of the line is y = 7.5x + 0, or y = 7.5x.
