There are 6 possible outcomes per roll and three 3 rolls = 6 x 6 x 6 = 216 possible outcomes, assume by outcome one counts each possible sequence separately. If you only count the sum of three rolls, then the possible outcomes are the integers from 3 to 18 inclusive, or 16 possible outcomes. Obviously you mean the former.

Answer:

216 outcomes.

Step-by-step explanation:

When you roll one 6 sided die you have a 1/6 chance,

[tex]\geq 18[/tex]

Step-by-step explanation:

Since this is in the math category I am assuming you needed a math answer.  The "greater than or equal to" symbol is the mathematical equivalent of "at least" some amount or number.

Answer:

x ≥ 18

Step-by-step explanation:

x ≥ 18 (I don't know if you've gotten to greater than or equal to, but keep in mind the answer might be ">" instead of "≥" if its the only option in multiple choice)

x is the age you have to be to vote, the greater than or equal to sign it to say that you have to be older than or equal to 18, and the 18 is the number/age you at least have to be!

Given that

The quadrilateral ABCD's vertices are located at A(-6,-1), B(-5,2), C(-1,5), and D. (0,-2).

According to the statement

We have to find that the whether the quadrilateral is a parallelogram or not.

So, For this purpose, we know that the

A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

From the given information:

The coordinates of the vertices of quadrilateral ABCD are A(-6,-1), B(-5,2), C(-1.-5), and D(0.-2).

Then

To show that the diagonals are bisect each other, we have to find the midpoint of both diagonals and if the midpoint is same then they bisect each other.

So,

Midpoint of AC = Midpoint of BD

Midpoint of A(-6,-1),C(-1.-5)  = Midpoint of B(-5,2),D(0.-2)

( -6-1/2 , -1-5/2) = (-5+0/2 , 2-2/0)

( -7/2 , -6/2) = (-5/2 , 0/2)

And these midpoints are not same then they do not bisect each other and then it is not a parallelogram.

Given data

perimeter of a right angled triangular park is 120m

area is 600m^2

Perimeter of triangle = b + h + √(b^2 + h^2)

Area of triangle = 0.5 * b * h = 0.5bh

120 = b + h + √(b^2 + h^2)   equation 1

600 = 0.5bh                          equation 2

form equation 2

bh = 1200

from  equation 1

120 - b - h = √(b^2 + h^2)  

( 120 - b - h )^2 = (b^2 + h^2)

( 120 - b - h ) * ( 120 - b - h ) = (b^2 + h^2)

14400 - 120b - 120h - 120b + b^2 + bh - 120h + bh + h^2 = (b^2 + h^2)

14400 - 240b - 240h  + b^2 + 2bh + h^2 = b^2 + h^2

14400 - 240b - 240h  + 2bh = 0

and bh = 1200

14400 - 240b - 240h  + 2 * 1200 = 0

14400 - 240b - 240h  + 2400 = 0

16800 - 240( b + h ) = 0

16800 = 240( b + h )

b + h = 70

b = 70 - h

and bh = 1200

h ( 70 - h ) = 1200

70h - h^2 = 1200

h^2 - 70h + 1200 = 0

h = 40 or 30

if h = 30

and bh = 1200

b = 1200/30

b = 40

(y = 2.05x) is the equation that relates the change in price per sticker purchased.

The equation of exchange is an economic identity that shows the relationship between money supply, the velocity of money, the price level, and an index of expenditures. English classical economist John Stuart Mill derived the equation of exchange, based on earlier ideas of David Hume. It says that the total amount of money that changes hands in the economy will always equal the total money value of the goods and services that change hands in the economy.

Given that: For every ten sheets you buy the total cost increases $20.50.

• The number of stickers purchased = 10

• Price change = $20.50

The change in price per sticker purchased can be expressed as:

• Price change / number of stickers

• Change in price per sticker = $20.50 / 10

• Change in price per sticker purchased = 2.05

Therefore, the required equation which related y and x is: y = 2.05x

We have to find that the area of the triangle.

So, For this purpose, we know that the

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.

From the given information:

Triangle QRS, with vertices Q(6,2), R(7.7), and S(2,6)

Then we know that the

The coordinate geometry formula for area = the absolute value of Qx(Ry - Sy) + Rx(Sy - Qy) + Sx(Qy - Ry) divided by 2.

Then substitute the values:

Area = the absolute value of Qx(Ry - Sy) + Rx(Sy - Qy) + Sx(Qy - Ry) divided by 2.

Area = the absolute value of 6(7- 6) + 7(6- 2) + 2(2- 7) / 2.

Area =  6(7- 6) + 7(6- 2) + 2(2- 7) / 2.

Area =  6(1) + 7(4) + 2(-5) / 2.

Area =  6 +28 -10 / 2.

Answer:

y= -6/7x+8

Step-by-step explanation:

7x-6y=13

6y=7x-13

y=7/6x-13/6

a perpendicular line has the x-axis as the reciprocal and the opposite

so

y= -6/7x+b

and to find b you take the x-axis, in this case, it is 14, multiply 14 by the slope which is -6/7. 14x-6/7= -12

-12 plus what number is -4? it's 8! -12+8=-4 b=8

so you get y=-6/7x+8

Answer:

There is no “formula” and the sooner you stop believing that math is a collection of formulas the sooner you can start learning it.

“Y sinx”, as written, is meaningless. You probably meant y = sin(x). Learning the proper grammar and syntax for writing mathematical expressions is necessary to make any progress in the subject.

Finally, the value of y = sin(x) is the y-coordinate of a point on the unit circle at position angle x. the zeros of y = sin(x) are x = k*pi, where k is any integer, because at any of those position angles the y-coordinate will be 0. This is not a “formula”, just a compact way to indicate an infinite number of zeros. The note that k is any integer is generally assumed, but to be clear and precise it should be included as part of the answer.

Solutions to trig equations are often restricted to the domain [0, 2pi), which is once around the unit circle without repetition of any point. On this domain, the zeros are 0 and p

The measurement of angle ∠D in parallelogram CDEF would be 89° and

the measurement of angle ∠D in parallelogram ABCD would be 57°.

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

In parallelogram CDEF,

∠C = ∠D

87 = 93 + 2x

2x = 87 - 93

2x = -6

x = -3

So the measurement of ∠D = 93 + 2(-2) = 89

In parallelogram ABCD,

∠A =∠C

57 = 3x + 21

3x = 57 - 21

3x = 36

x = 12

So the measurement of ∠C = 3(12) + 21 = 57

Hence, the measurement of angle ∠D in parallelogram CDEF would be 89° and the measurement of angle ∠D in parallelogram ABCD would be 57°.

Mega Dumpster rents the same size dumpster for $300, but only charges $90 per ton of waste.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
accoding to the question,
225 + 130w > 300 + w90
130w - 90w > 300 - 225

Answer:  [tex]\frac{dy}{dx}[/tex] = [tex]\frac{ 7 - sin y }{ -6 y^{2} + x cos y }[/tex]

Step-by-step explanation:

Given data,

                       x sin y - 2y^3 - 5 = 7x

Differentiate with each term with respect to the independent variable,

            [tex]\frac{d}{dx}[/tex] (x sin y) - [tex]\frac{d}{dx}[/tex] (2y^3) - [tex]\frac{d}{dx}[/tex] (5) = [tex]\frac{d}{dx}[/tex] (7x)  

Apply to the product rule,

         sin y * [tex]\frac{d}{dx}[/tex] (x) + x * [tex]\frac{d}{dx}[/tex] (sin y) - [tex]\frac{d}{dx}[/tex] (2 [tex]y^{3}[/tex]) - [tex]\frac{d}{dx}[/tex] (5) = [tex]\frac{d}{dx}[/tex] (7x)

Apply the chain rule,

sin y * [tex]\frac{d}{dx}[/tex] (x) + x* [tex]\frac{d}{dy}[/tex] (sin y) * [tex]\frac{dy}{dx}[/tex] - [tex]\frac{d}{dy}[/tex] (2 [tex]y^{3}[/tex])* [tex]\frac{dy}{dx}[/tex] - [tex]\frac{d}{dx}[/tex] (5) = [tex]\frac{d}{dx}[/tex] (7x)

Take out the coefficients,

sin y * [tex]\frac{d}{dx}[/tex] (x) + x * [tex]\frac{d}{dy}[/tex] (sin y) * [tex]\frac{dy}{dx}[/tex] -2 [tex]\frac{d}{dy}[/tex] ([tex]y^{3}[/tex]) *  [tex]\frac{dy}{dx}[/tex] - [tex]\frac{d}{dx}[/tex] (5) = 7 * [tex]\frac{d}{dx}[/tex] (x)

Differentiate the constants and power functions,

 sin y + x * [tex]\frac{d}{dy}[/tex] (sin y) * [tex]\frac{dy}{dx}[/tex] - 2 * 3 * [tex]y^{2}[/tex] * [tex]\frac{dy}{dx}[/tex] = 7    

Differentiate sin (x),

  sin y + cos y * [tex]\frac{dy}{dx}[/tex] - 2 * 3 * [tex]y^{2}[/tex] * [tex]\frac{dy}{dx}[/tex] = 7

Isolate,

             [tex]\frac{dy}{dx}[/tex] = [ 7-sin y ] / (-6 [tex]y^{2}[/tex] + x cos y )

Therefore,

              [tex]\frac{dy}{dx}[/tex] = [tex]\frac{ 7 - sin y }{ -6 y^{2} + x cos y }[/tex]
