The probability of getting 6 in second roll is 0.1388  and on 3rd roll is  0.1157.

The mathematical discipline of probability is concerned with numerical descriptions of the likelihood of an event or proposition being true. A number between 0 and 1 indicates the likelihood of an event, with 0 representing impossibility and 1 representing certainty. The more likely it is that an event will occur, the higher its probability. The tossing of a fair (unbiased) coin is an easy illustration.

Given

A fair die is rolled repeatedly until a six is obtained.

The probability of getting a 6 in the second toss is

P(X = 2) = (1 - 1/6)1/6

P(X = 2) = 5/36 = 0.1388

The probability of getting a 6 in the third toss is

P(X = 3) = (1 - 1/6)(1 - 1/6)1/6

P(X = 3) = 5/6 x 5/6 x 1/6

P(X = 3) = 25/216

P(X = 3) = 0.1157

Hence the  probability on second roll is 0.1388 and on third roll is 0.1157.

What is the solution to this equation? 7-1^3 √2-x=12

X=5

Answer:

x = 127

Step-by-step explanation:

[tex]7-\sqrt[3]{2-x} = 12[/tex] , add the cube root to both sides and subtract the 12

[tex]7-12 = \sqrt[3]{2-x}[/tex], combine like terms

[tex]-5 = \sqrt[3]{2-x}[/tex], raise both sides to the third power

[tex](-5)^{3} = (\sqrt[3]{2-x} )^{3}[/tex], simplify

[tex]-125= 2-x[/tex] , to isolate the variable subtract 2 from both sides

[tex]-125-2 =-x[/tex], combine like terms

[tex]-127=-x[/tex], multiply both sides by -1

Answer:

y=4x-8

Step-by-step explanation:

Slope= y1-y2/x1-x2

Slope = 4- (-16)/3-(-2)=4+16/3+2=20/5=4

Equation: y=4x+b

Let y=4 and x=3

4=12+b

b= -12+4

b=-8

Therefore: y=4x-8

Answer:

r=3.25

Step-by-step explanation:

3 divided by 0.5=6

6-2.75=3.25

r=3.25

Answer:

r = 3.25

Step-by-step explanation:

Isolate the variable, r. Note the equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

~

First, divide 0.5 from both sides of the equation:

(0.5(r + 2.75))/0.5 = (3)/0.5

r + 2.75 = 3/0.5

r + 2.75 = 6

Next, subtract 2.75 from both sides of the equations:

r + 2.75 (-2.75) = 6 (-2.75)

r = 6 - 2.75

r = 3.25

r = 3.25 is your answer.

Answer:

mmmm feet

Step-by-step explanation:

!!!!

Answer:

umm ok look it up bc I need to do this as a step

Step-by-step explanation:

the perimeter is the easiest, really. we only need to add all side lengths. there is nothing else to the perimeter calculation.

so,

perimeter = 6.5 + 2.5 + 6 = 9 + 6 = 15 ft.

area is also relatively easy for right-angled triangles, because the sides that enclose the 90° angle, act also as height of the triangle to each other.

so, it is a half-rectangle, and we only need to multiply these 2 sides (not including the Hypotenuse) and divide this by 2.

area = 6×2.5/2 = 3×2.5 = 7.5 ft²

Step-by-step explanation:

59 percent times 63 in total marbles is 37

The expression is equivalent to 4x = -32.

Given

Expression; [tex]\rm \dfrac{2}{3}(6x+12)[/tex]

To find the equivalent expression evaluates the value of the expression then check both are equal to each other or not.

Then,

The expression is equivalent to;

[tex]\rm \dfrac{2}{3}(6x+12)=-24\\\\ 2(6x+12)=-24\times 3\\\\12x+24=-72\\\\12x=-72-24\\\\ 12x=-96\\\\Divided \ by \ 3 \ on \ both \ sides\\\\ 4x=-32[/tex]

Answer:

Step-by-step explanation:

Answer:

y = 0

x = 8

Step-by-step explanation:

subtract second equation from first one

3x - 6y - (3x - y) = 24 - 24 the - sign in front of the parenthesis effects the inside expressions

3x - 6y - 3x + y = 24 - 24 add/subtract like terms

-5y = 0 and so y = 0

to find the value of x we can use this information

3x - y = 24 since y = 0

3x = 24 divide both sides by 3

x = 8

  C)  y -2 = 5/2(x -2)

Step-by-step explanation:

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

__

For slope m = 5/2 and point (2, 2), the equation is ...

  y -2 = 5/2(x -2) . . . . . . matches choice C

_____

Additional comment

One way to tell if you have the correct answer is to see if the given point satisfies the equation.

  A) 2 +2 = 5/2(2 +2)   ⇒   4 = 10 . . . false

  B) 2 +2 = -5/2(2 -2)   ⇒   4 = 0 . . . false

  C) 2 -2 = 5/2(2 -2)   ⇒   0 = 0 . . . true

  D) 2 +2 = 5/2(2 -2)   ⇒   4 = 0 . . . false

If you were to get a "true" for more than one, then you can try another point at (h +1, k +m).

__

Using this form, you are essentially translating the line y = mx so it goes through the point (h, k), instead of (0, 0).
