The coefficient of skewness is 0 and coefficient of Kurtosis is 0.125.
A coefficient is a number or any symbol representing a constant value that is multiplied by the variable of a single term or the terms of a polynomial. It is usually a number, but sometimes may be replaced by a letter in an expression. For example, in the expression: ax2 + bx + c, x is the variable and 'a' and 'b' are the coefficients.
coefficient refers to a number or quantity placed with a variable. It is usually an integer that is multiplied by the variable and written next to it. The variables which do not have a number with them are assumed to be having 1 as their coefficient.

What is the triangle proportionality theorem?The triangle proportionality theorem states that, in a triangle, a line drawn parallel to one of the sides of a triangle and intersects the other two sides at two different points, then the ratio in which the other two sides are divided by the line are the same.
8. The triangle proportionality theorem indicates, if [tex]\overline{ST}[/tex] and [tex]\overline{PR}[/tex] are parallel, [tex]\overline{ST}[/tex] ║ [tex]\overline{PR}[/tex], we get; QS/SP = QT/TR
QS/SP = 7/11.2 = 0.625

What is the area that is painted?
Use π≈3.14.
Enter your answer, rounded to the nearest tenth, in the box.
Answer:
128π in.² ≈ 402.1 in.²
Step-by-step explanation:
The rod can be cut into two equal sized pieces in different ways, so there are different answers to this question. I assume the question is asking when the rod's length is cut in half, so now there are two rods, each one being a cylinder with 4 inch height.
We need the area of the original rod and then add two more base areas.
C = 8π in.
r = 4 in.
total surface area = lateral area + 4 × area of base
SA = 8 in. × 8π in. + 4 × π × (4 in.)²

Which is a correct solution for the system of inequalities?When we have a system of inequalties (so we have 2 or more inequalities) the solutions are the points (x, y) that are solutions of both inequalities at the same time.
Here we can see the graph of a system, such that the solution set of one of the inequalities is represented by the red shaded area, and the solution set of the other inequality is represented by the blue shaded area.
The solution set of the system is represented by the intersection between the areas, which is the purple area.

o (7.5, 4.5)
The ordered pair could represent the image of point C(5, 2) after the dilation is (2.5, 1)
Which ordered pair could represent the image after the dilation?If we have a general point (x, y) and we apply a dilation with the origin as the center of a scale factor k, then the coordinates of the image after the dilation is (k*x, k*y)
Here we want to see which point can be the image of (5, 2) after the dilation, it will must have the form (k*5, k*2)
The only point that has this form is the one on the third option, where we can write:
(2.5, 1) = (k*5, k*2)
Then we have two equations:
2.5 = k*5
1 = k*2
Solving these we should get the same value of k.
2.5/5 = k = 0.5
1/2 = k = 0.5

What are inequalities?In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
The given expression is:
-15< 3n < 6
Divide all the sides of the equation with 3 to isolate the value of n.

Find the equation of the perpendicular bisector of AB where A and B are the points (3,6) and (-3,4) respectively. Also find its point of intersection with (i) x-axis and (ii) y-axis.
The point of intersection with x - axis is (5/3,0) and the point of intersection with y - axis is (0,5).
Any point on AB's perpendicular bisector, P(x,y), shall be considered. Then, PA = PB.
√(x-3)²+(y-6)² = √(x+3)²+(y-4)²
(x-3)²+(y-6)² = (x+3)²+(y-4)²
x² -6x+ 9 + y²- 12y + 36 = x² +6x+ 9 + y²- 8y + 16
12x + 4y -20 = 0
3x+ y-5 =0 ---(1)
Consequently, 3x+y-5=0 is the equation for the perpendicular bisector of AB.
We know that the coordinates of any point on x-axis are of the form (x,0). In other words, any point on the x-axis has a y-coordinate of zero. Thus, if we enter y = 0 in (1), we get
3x -5 = 0
x = 5/3
Thus, the x-axis is cut by the perpendicular bisector of AB at (5/3, 0).
(ii) Any point's y-axis coordinates have the following format: (0,y). When we enter x = 0 in (1), we obtain
y − 5 = 0
⇒ y = 5
Thus, the y-axis is where the perpendicular bisector of AB intersects (0,5).

What is a Quadratic equation?ax2+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
Given, David took out a 20-year $70,000 loan from his bank in 2010.
The quadratic equation that approximates the year/loan balance relationship is y = -98*x^2 - 1,531x + 69,718,
where x is the number of years and
y is the balance
Since the Loan balance is given $37,234.
Thus to calculate the year
$37,234 = -98*x^2 - 1,531x + 69,718,
98 x² + 1534x - 32484 = 0
Comparing with the general form of the quadratic equation.
ax² + bx + c = 0
The discriminant b² - 4ac > 0 thus it has Two real roots.
using the Quadratic Formula
x = [tex]\frac{-b +- \sqrt{b^{2} - 4ac } }{2a}[/tex]
x = -27.62

a spherical snowball is rolled in fresh snow causing it grow so fast that its radius increases at a rate of 2 in/sec. how fast is the volume of the snowball increasing when the radius is 9 in
The volume is increasing at a rate of 784 * pi cubic inches per second.
The volume of a sphere is given by the formula V = (4/3) * pi * r^3, where r is the radius of the sphere.
We can find the rate of change of the volume with respect to time by taking the derivative of V with respect to time.
dV/dt = (4/3) * pi * 3r^2 * dr/dt
Given that the radius is increasing at a rate of 2 in/sec, we can substitute this value into the equation and find the rate at which the volume is increasing:
dV/dt = (4/3) * pi * 3 * 9^2 * 2 in^3/sec = 784 * pi in^3/sec
So, when the radius of the snowball is 9 inches, the volume is increasing at a rate of 784 * pi cubic inches per second.

Can you write an Orginal Oratory speech on benefits of solar energy
Throughout the solar system, solar energy is continuously emitted by the sun. The Earth is warmed by solar energy, which also affects the weather, the wind, and the survival of plant and animal life. Electromagnetic radiation, which is a kind of energy, heat, and light, is released from the sun (EMR).
What is solar system?Anything produced by the sun is considered to be solar energy.Nuclear fusion that occurs in the sun is the source of solar energy. Hydrogen atom protons clash ferociously in the sun's core, where they fuse to form helium atoms, which is the process of fusion.An large quantity of energy is released during this process, which is sometimes referred to as a PP (proton-proton) chain reaction. Around 620 million metric tons of hydrogen are fused by the sun every second in its core. Other stars, similar in size to our sun, also experience the PP chain reaction, which supplies them with ongoing heat and energy. These stars have an average Kelvin temperature of 4 million degrees (about 4 million degrees Celsius, 7 million degrees Fahrenheit).The CNO cycle is responsible for energy production in stars that are around 1.3 times larger than the sun. Carbon, nitrogen, and oxygen (C, N, and O) are required for the CNO cycle to convert hydrogen to helium. As of right now, the CNO cycle produces less than 2% of solar energy.To Learn more About solar system, refer To:

V 224

The square root of 224 in long division is 14.96
The term square root in math is defined as a factor of a number that, when multiplied by itself, gives the original number
Here we know that we need to find the square root of √224.
In order to solve this one we have to do the following steps,
Here we have to start dividing the digits from the right side into pairs of two by drawing a line on top of them. In the case of 224, then we have two pairs 24 and 2.
And then we have to find a number(z) whose square is ≤ 2.
Then the value of z will be 1 as 1 × 1 = 1 ≤ 2.
Here we get the value of quotient and the remainder as 1 and now we have to add the divisor z with itself and get the new divisor 2z (2).
And then we have to drag down the next pair and find a number (n) such that 2n × n ≤ 124 here we have the value of n comes out to be 4.
Finally we have to add a decimal in the dividend (224) and quotient (14) simultaneously.
Here we have to add 2 pairs of zero in the dividend after the decimal and repeat the above step for the remaining three pairs of zero.
