Find x. Please help I’m stuck

Answer:

The expected value is $2.1

Step-by-step explanation:

If we have an event with some given outcomes:

x₁, x₂, ..., xₙ

Such that each one of these outcomes has the correspondent probability:

p₁, p₂, ..., pₙ

The expected value is:

EV = p₁*x₁ + ... + pₙ*xₙ

In this case we have a table with the events (the payouts) and the probability for each one, so we have:

x₁ = $0

p₁ = 0.5

x₂ = $2

p₂ = 0.2

x₃ = $4

p₃ = 0.15

x₄ = $6

p₄ = 0.1

x₅ = $10

p₅ = 0.05

Now we can just replace these in the expected value equation, so we get:

EV = $0*0.5 + $2*0.2 + $4*0.15 + $6*0.1 + $10*0.05 = $2.1

Answer:

<K = 67degrees

Step-by-step explanation:

From the parallelogram given, the opposite angles are equal i.e <L = <J

Given

<L = 5x + 18

<J = 7x - 20

Equating both sides

5x +  18 = 7x - 20

Collect the like terms

5x - 7x = -20 -18

-2x = -38

x = 38/2

x = 19

Also <J + <K = 180

7x - 20 + <K = 180

7(19) - 20 + <K = 180

133  - 20 + <K = 180

113 + <K = 180

<K = 180 - 113

<K = 67degrees

Answer:

A. 320 sq. ft.

B. $1920

Step-by-step explanation:

You need to find 5 sides. They are all 8*8. 64*5 is 320. Now, you multiply that by 6 to get $1920

Answer:

60 minutes

Step-by-step explanation:

Here is the complete question

Caylan is making baked goods for a charity bake sale. He places a tray of scones, a tray of muffins, and a tray of cookies in the oven. The scones bake for 15 minutes, the muffins bake for 12 minutes, and the cookies bake for 10 minutes. When one tray is done, he removes it and replaces it with another tray of the same item. How many minutes after Caylan puts the trays in the oven will he first remove the scones, muffins, and cookies at the same time? ? minutes​

The multiples for scones = 15 = 3,5

The multiples for muffins = 12 =2, 2,2,3

The multiples for cookies = 2, 5

Lowest common multiple = 2 x 2 x 3 x 5 = 60 minutes

to determine the time , calculate the lowest common multiple of 12, 15 and 10

Answer:

60 - This is due to the times of each and what time you would take them out.

Answer:

x=3.5

Step-by-step explanation:

Answer:

x=sqrt(12) or 2sqrt(3)

Step-by-step explanation:

You can just use pythagorean theorem for this.

We can do 4^2+x^2=8^2

This gives us 16+x^2=64.

Simplify: x^2=48

x=sqrt(48)

Now, we can find x!

We just have to do 6^2+x^2=sqrt(48).

We get 36+x^2=48

simplify: x^2=12

Now, x=sqrt(12) or 2sqrt(3)

If I remember how to solve these questions correctly, if there is a triangle that is 45 degrees, the hypotenuse will be times the square root of 2 of the other two sides (which are equal to eachother). Hope this helped!

Answer:

[tex] \cos(45 \degree) = \frac{3 \sqrt{2} }{x} \\ x = \frac{3 \sqrt{2} }{ \cos(45 \degree) } \\ x = 6[/tex]

Answer:

D

Step-by-step explanation:

Answer:

y = 30

x = 60

Step-by-step explanation:

4y and 2y are consecutive angles, which means they are equal to 180° when added together

that is the same with x and (5x - 180)

to solve, you set the equations to 180

solving:

4y + 2y = 180

6y = 180

y = 30

x + 5x - 180 = 180

6x = 360

x = 60

Answer:

37.7 cm

Step-by-step explanation:

C=2πr=2·π·6≈37.69911

Answer:

37.68 cm.

Step-by-step explanation:

The formula for circumference of a circle is: πd (diameter)

The radius of this circle is 6 centimeters.

To find the diameter, multiply the radius by 2.

6 × 2 = 12.

12 is the diameter.

Lastly, multiply the diameter by pi.

**3.14 IS A SUBSTITUTE FOR PI**

3.14 = 37.68.

Therefore, the circumference of this circle is 37.68 cm.

Answer:

490π

Step-by-step explanation:

Given data

Diameter= 14 inches

Radius= 7 inches

Height = 10 inches

The expression for the volume of a cylinder is

V= πr^h

V= π*7^2*10

V= 490π

Hence the volume is 490π
