Lose $13.16

Here, we want to calculate the probability that we would win. The probability of winning is =

( No. of slots that win/ total no. of slots.)

For each individual spin, there  are two possible outcomes:

- There is a 1 in 38 chance of winning $175.

- There is a 37 in 38 chance of losing $5.

The expected value for each spin is the sum of the products of each outcome by their respective probability.

expected value =E1×P1 + E2×p2

175×1/38 + (-5) × 37/38

175/38 - 185/38

-10/38

In 50 spins, the expected value is:

E(50) = 50 × (-10/38)

E(50) =  - $13.16

expect to lose $13.16 if you spin the wheel 50 times.

the equations y = - x - 4 and - 7 x + 8 y = 16 have the solution as x = - 16 / 5 and y = - 4 / 5.

We are given the two equations:

y = - x - 4

- 7 x + 8 y = 16

We need to solve these equations by substitution.

We will substitute the equation 1 in the equation 2 to get the values of x and y:

- 7 x + 8 y = 16

- 7 x + 8 (- x - 4) = 16

- 7 x - 8 x - 32 = 16

- 15 x = 16 + 32

- 15 x = 48

Divide both sides by - 15, we get that:

x = 48 / - 15

x = - 16 / 5

y = - x - 4

Put the value of x

y = 16 / 5 - 4

y = 16 - 20  / 5

Subtract to get the value:

y = - 4 / 5

Therefore, we get that, the equations y = - x - 4 and - 7 x + 8 y = 16 have the solution as x = - 16 / 5 and y = - 4 / 5.

If the baker has a total of 1/2 bags of flour, the total weight of the bags of flour is 1.625

What is the weight of a bag of flour in pounds?

The fact that each bag of flour weighs 3 and 1/4 pounds means that each bag of flour is 3.25 pounds, in essence, the total weight of flour that the baker has can be determined as the weight of a bag of flour multiplied by the total of 1/2 bags of flour.

total weight of bags of flour=weight of a bag of flour*total weight of baker's flour

weight of a bag of flour=3.25 pounds

total weight of baker's flour=1/2 bag

total weight of bags of flour=3.25bags*1/2

The measurement of angle A and B is 44° and 46° respectively.

What are complementary angles ?

When the sum of two angle is 90 degree it is known as complementary angles and when a line divides the line than the sum of angles formed with the given straight line is always equals to 90 degree.

It is given that the angle A and B are complementary angles whose measurements are :

∠A = (6x + 2)°

and , ∠B = (4x + 18)°

The sum of angle A and B will be 90 degree as they are complementary angles that is :

∠A + ∠B = 90°

Now, solving by adding like terms and finding the value of x :

6x +2 + 4x + 18 = 90°

10x + 20 = 90°

10x = 90-20

10x = 70°

x = 7°

now, the measurement of angle A will be :

∠A = (6x + 2)°

∠A = (6 · 7 + 2)°

∠A = (42 + 2)°

∠A = 44°  and  ∠B = 46°

Therefore, the measurement of angle A and B is 44° and 46° respectively.

The length of the diagonal (D) of this rectangular prism is equal to 9.5 feet.

Pythagorean theorem can be defined as a mathematical expression in Euclidean geometry that can be used to solve for any of the three (3) side lengths of a right triangle.

In order to determine the length of the diagonal (D) of this rectangular prism, we would first of all determine the diagonal of the base by applying Pythagorean theorem:

d² = l² + b²

d² = 4² + 7²

d² = 16 + 49

d² = 65

d = √65

Now, we can determine the length of the diagonal (D) of this rectangular prism:

D² = d² + h²

D² = √65² + 5²

D² = 65 + 25

D² = 90

D = √90

Diagonal, D = 9.5 feet.

Therefore, the length of the diagonal (D) of this rectangular prism is equal to 9.5 feet.

43.75 divided by 7 is 6.25, thus your answer is 6.25 hours

Answer: Yes, all horizontal lines have slope of 0

Reason:

Recall that slope = rise/run

The rise tells us how far to go up or down. A horizontal line does neither. There's no change in y value.

So we have slope = rise/run = 0/run = 0, where "run" is any positive number you want. The run is how far to the right we go each time moving up or down.

Answer: Yes

Step-by-step explanation:

When you have a horizontal line it is flat and has no slope at all

So the slope = 0

Both 3 is an extraneous solution.

We have the equation x - 6 = [tex]\sqrt{3x}[/tex]

To find the value of x we need to square on both side of the equation

[tex](x-6)^{2}[/tex] = [tex](\sqrt3{x} )^{2}[/tex]

[tex]x^{2}[/tex] - 12x + 36 = 3x

[tex]x^{2}[/tex] -15x + 36 = 0

[tex]x^{2}[/tex] - 12x - 3x + 36 = 0

x ( x- 12 ) - 3( x - 12) = 0

(x -12 ) ( x - 3) = 0

Therefore we get x = 12 , 3

Now we will put both the value of x in the equation

x - 6 = [tex]\sqrt{3x}[/tex]

Let put 12 first

12 - 6 = [tex]\sqrt{3 * 12}[/tex]

6 = 6
