Let X be the sum of the roll of two fair six-sided dice. Find P[X = 8 | X = 7 or X = 8]

Hi there!

Hope this helps!

Answer: 3.297 centimeters.

Step-by-step explanation:

First, remember that if we have a circle of radius R, and we have an arc of angle A, the length of this arc is:

L = (A/360°)*2*3.14*R

In this case, we can think on a circle of radius R = 6cm.

And the angle in this case will be an angle of 5 minutes and 15 seconds.

We know that a clock does a complete revolution in 60 minutes, then:

60 minutes = 360°

First, we need to write 5 minutes and 15 seconds in minutes only.

we know that 60 seconds = 1min

then:

1 = 1min/60seconds = (1/60) min/seconds

then:

15 seconds = 15 seconds*((1/60) min/seconds) = (15/60) min = 0.25 min

Then:

5 minutes and 15 seconds = 5 min + 0.25 min = 5.25 min

Now we can use the relationship:

60 minutes = 360°

then:

1 = 360°/60min

Then:

5.25min = (5.25min)*(360°/60min) = 31.5°

Then we have A = 31.5°

Then the length of this arc (that is the distance that the tip of the tip travels in 5 minutes and 15 seconds) is:

L = (31.5°/360°)*2*3.14*6cm = 3.297 cm

Answer:

a:     0.43194

b:     0.09084

Step-by-step explanation:

First construct the z values for 498 and 506.

[tex]z=\frac{x-u}{s}[/tex]

[tex]z(498)=\frac{498-500}{35}[/tex]=-0.05714

z(506)=(506-500)/35=0.17143

Check the cumulative normal distribution tables to find

P(x<=-0.05714)=0.47722

P(x<=506)=0.52278

These probabilities imply that

P(x>506)=1-P(x<=506)=1-0.52278=0.43194

P(498<=x<=506)=P(x<=506)-P(x<=498)=0.09084

Answer:

18cm

Step-by-step explanation:

Perimeter of triangle= a+a+a (side + side+ side)

Perimeter of triangle= 6 cm+6cm+6cm

Perimeter of triangle= 18cm

Answer:

18cm

Step-by-step explanation:

6+6+6=18cm

since it is an equilateral triangle, so all side are the same

Answer:

4^19

Step-by-step explanation:

Answer:

4 inches tall

Step-by-step explanation:

To find how tall it will be, use the same reduction scale that was used to reduce the width.

This scale is 5, since 5 divided by 5 is 1.

So, to find how tall it will be, divide 20 by 5:

20/5

= 4

So, it will be 4 inches tall

Answer:

Film A = 128 min

Film B = 32 min

Step-by-step explanation:

let 'B' = length of film B

let '4B' = length of film A

4B + B = 160

5B = 160

B = 32

4B = 128

Answer:

Step-by-step explanation:

Algebraic expression: 4x - 2y

Algebraic equation: 4x - 2y = 15

Term(s): 4x, -2y

Coefficient(s); 4, -2

Constant(s); no constants

Variable(s): x, y

expressions don't have an equal sign, equations do

terms are separated by operational signs (multiplication, division, addition, subtraction)

Coefficients are the numbers before variables

Constants aren't variables

Variables are letters

Answer:

9^4

Step-by-step explanation:

There is 4 nines.

9*9*9*9 = 6561

9^4 = 6561

9^3 = 729

Answer:

5:4

Step-by-step explanation:

90 = 9 × 2 ×5

72 = 9 × 2 ×2 ×2

So, 90:72 = 5: 4

Hope the above solution will help you

Answer:

to Make it in simplest form

firstly we need to take GCF of each

and after it divide both term with their GCF

like GcD of 90 and 72 is 18

and after dividing both by 18

we get 5/4

this is the answer

5/4

Answer:

Step-by-step explanation:

Remark

You are going to have to find the angle on the lower right before you can get the answer. Call the angle on the lower right = x

Equation

Sin(60)/7 = sin(x) / 3

Solution

3 * sin(60) / 7 = sin(x)

Sin(60) = 0.866

3*0.866 / 7 = sin(x)

sin(x) = 0.3712

x = sin-1(0.3712)

x = 21.79

Now calculate the 3rd angle call it y

y + 21.79 + 60 = 180

y + 81.79 = 180

y = 180 - 81.79

y = 98.21

Now use the sin law again.

Let ? = z

z/sin(98.21) = 7/sin(60)              Multiply both sides by sin(98.21)

z = 7 * sin(98.21) / sin(60)

z = 6.9282 / sin(60)

z = 8

? = 8

Step-by-step explanation:

Answer:

x = -1

x = 5

Step-by-step explanation:

Use pythagorean theorem: a² + b² = c²

x² + (2x + 2)² = (2x + 3)²

Since these are quantities, you'll have to make them into quadratic equations.

(2x + 2)(2x + 2) = 4x² + 4x + 4x + 4

(2x + 3)(2x + 3) = 4x² + 6x + 6x + 9

x² + 4x² + 4x + 4x + 4 = 4x² + 6x + 6x + 9

Combine like terms

5x² + 8x + 4 = 4x² + 12x + 9

Move one side to set the equation equal to 0

x² - 4x - 5 = 0

Solve

x² - 5x + x - 5 = 0

x(x - 5) + 1(x - 5) = 0

(x + 1)(x - 5) = 0

x = -1, 5

We can check that these are correct by plugging them in for x and seeing if they are equal

For example

(-1)² + (2(-1) + 2)² = (2(-1) + 3)²

1 = 1
