The three methods to find the mean are arithmetic, geometric and harmonic .
The arithmetic mean method: This method involves adding up all the values in the set and dividing by the total number of values. This gives the average value of the set.The geometric mean method: This method involves finding the product of all the values in the set and taking the square root of that product. This gives the average value of the set when the values represent quantities that are multiplied together (such as interest rates or growth rates).The harmonic mean method: This method involves taking the reciprocal of each value in the set (1/value), adding those reciprocals up, and taking the reciprocal of that sum. This gives the average value of the set when the values represent quantities that are inversely related (such as speeds or rates).To learn more about mean, visit:

A polynomal of degree of 2 that has zeros -4 and 2 is
9514 1404 393
Answer:
f(x) = x^2 +2x -8
Step-by-step explanation:
If p and q are zeros of a quadratic, its factored form is ...
f(x) = (x -p)(x -q)
For your zeros, the factored form is ...
f(x) = (x +4)(x -2)
Expanded using the distributive property, this is ...
f(x) = x(x -2) +4(x -2) = x^2 -2x +4x -8
f(x) = x^2 +2x -8

What is the prime factorization of 110?
Answer:
The prime factors of 110 are 2, 5, and 11.
Step-by-step explanation:
First, 110 = 2 * 55
Next, 55 = 5 * 11
Thus, the prime factors of 110 are {2, 5, 11}
Answer:
2 x 5 x 11 = 110.
Step-by-step explanation:
The prime factors of 110 are 2, 5, and 11.
-Factors of 110: 1, 2, 5, 10, 11, 22, 55 and 110
-Prime Factorization of 110: 110 = 2 × 5 × 11
1 × 110 = 110
2 × 55 = 110
5 × 22 = 110
10 × 11 = 110
11 × 10 = 110
22 × 5 = 110
55 × 2 = 110
110 × 1 = 110
which of the following equations represents a line that passes through the points
Answer:
C) I only
Step-by-step explanation:
( -1, -2) and (0,4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4+2)/(0+1)
m=6/1
m=6
Slope-intercept:
y - y1 = m(x - x1)
y + 2 = 6(x + 1)
y + 2 = 6x + 6
y = 6x + 4
y - 16 = 6(x - 2)
y - 16 = 6x - 12
y = 6x + 4
What is the equation of the line with slope −3 and y-intercept 6? Express your answer in slope-intercept form.
A. y = 3x + 6
B. y = −3x − 6
C. y = −3x + 6
D. y = 3x − 6
Answer:
C. y = -3x +6
Step-by-step explanation:
y = mx + b
m= slope = -3
b = y-intercept = 6
y = -3x + 6

What is the area of the base?
Answer:
24 in²
Step-by-step explanation:
Hello there!
the figure shown is a triangular prism
The base is the triangle
So we need to find the area of the triangle using this formula
[tex]A=\frac{bh}{2}[/tex]
where b = base and h = height
The base (triangle) has a base length of 8 inches and a height of 6 inches
Having found the information we needed, we plug it into the formula
So
[tex]A=\frac{6*8}{2} \\6*8=48\\\frac{48}{2} =24\\A=24in^2[/tex]
So the area of the base is 24 in²
What is the length of side a? Round to the nearest tenth of an inch
Answer:
ok this is easy all it is 16-7=9 so a=9 so all it is 7x9=72 then its 72 divided by 2 so your answer is 36
If Amy bought 2 CDs for $14.00 each, a DVD for $24.99, and a video
game for $37.50, how much change would she get back from a $100 bill?
Answer: Change of $9.51
Step-by-step explanation: Use parenthesis to simplify this, 2(14) + 1(24.99)+1(37.50) = 100. Then subtract accordingly.
Answer:
9.51
Step-by-step explanation:
multiply the cost of the cds by 2, add the DVD and the video game, then subtract that answer with a 100 dollar bill.

Assume that BC is tangent to circle A. Find the value of x. Round your answer to the nearest tenth
Answer:
x ≈ 9.6
Step-by-step explanation:
Δ ABC is right with ∠ C = 90° ( angle between tangent and radius )
Using Pythagoras' identity in the right triangle
x² + 14² = 17²
x² + 196 = 289 ( subtract 196 from both sides )
x² = 93 ( take the square root of both sides )
x = [tex]\sqrt{93}[/tex] ≈ 9.6 ( to the nearest tenth )
A brick of lead weighs 6,328 grams and has the following dimensions: length of 20 cm, height
of 8 crn, and width of 35 mm. What is the approximate density of the lead? Round to the
nearest tenth
Answer:
11.3
Step-by-step explanation:
Volume: L * W * H
L = 20
W = 8
H = 35 mm = 35/10 = 3.5 cm
V = 20 * 8 * 3.5
V = 560 cm^3
Density = m/v
Density = 6328 / 560
Density = 11.3

what is the volume, in cubic centimeters, of a cylinder that has a height of 15 cm and a diameter of 12cm?
Answer:
Option 2[tex]540\pi[/tex]
Step-by-step explanation:
Given,
Diameter of the cylinder = 12cm
Radius of the cylinder = 12cm ÷ 2 = 6cm
Height of the cylinder = 15cm
Therefore,
Volume of the cylinder
[tex] = \pi {r}^{2} h[/tex]
[tex] = \pi \times 6 \times 6 \times 15 {cm}^{3} [/tex]
[tex] = 540\pi \: cubic \: cm[/tex]
Hence,
Option 2 is correct for volume of the cylinder in cubic cm:
[tex]540\pi[/tex]
Find the Area of this Composite Figure:
8 in
7 in
12 in
Answer:
132in²
Step-by-step explanation:
Find the area of the composite figure. Round your final answer to the tenth.
Answer:
181.5 in^2 to the nearest tenth.
Step-by-step explanation:
This consists of a rectangle and a triangle.
Area of the rectangle = 10 * 17 = 170 in^2
Area of the triangle:
The base = 17-13 = 4 in.
The height ( that is the vertical line below the rectangle) can be found using Pythagoras:
H = √(7^2 - 4^2) = √33
Area of the triangle = 1/2 * 4 * √33 = 11.489 in^2
Area of the whole figure = 170 + 11.489 = 181.489 in^2,

Me pueden ayudar? ☹ PROPIEDADES DE LA SUSTRACCIÓN DE NÚMEROS NATURALES: LA RESTA NO CUMPLE CON NINGUNA DE LAS CUATRO PROPIEDADES ENUMERADAS (agrega los contraejemplos) NO ES CERRADA EN EL CONJUNTO DE LOS NATURALES: porque... NO ES CONMUTATIVA: porque... NO ES ASOCIATIVA: porque... NO TIENE ELEMENTO NEUTRO: porque...
Answer:
(i) La sustracción de números naturales no es cerrada, puesto que no existe el resultado cuando el minuendo en menor que el sustraendo, es decir:
[tex]2 - 5 = -3, -3\notin \mathbb{N}[/tex]
(ii) La sustracción de números naturales no es conmutativa, pues al cambiar las posiciones entre minuendo y sustraendo, se pasar de un resultado contenido en [tex]\mathbb{N}[/tex] a uno no contenido en ese cuerpo. Es decir, el resultado cambia. Es decir:
[tex]5 - 2 = 3[/tex]
[tex]2 - 5 = -3, -3\notin \mathbb{N}[/tex]
(iii) La sustracción de números naturales no asociativa, pues al cambiar la posición de los paréntesis, puede llevar a un resultado distinto o inexistente en [tex]\mathbb{N}[/tex] debido a que el signo afecta a todo lo que está adentro del paréntesis. Es decir:
[tex](6-4) - 1 = 2 - 1 = 1[/tex]
[tex]6 -(4-1) = 6-3 = 3[/tex]
(iv) No tiene elemento neutro pues el neutro aditivo, léase 0, no pertenece a [tex]\mathbb{N}[/tex].
Step-by-step explanation:
