There are 38 pockets on an american roulette wheel: 18 red, 18 black, and 2 green. if you were to randomly spin an american roulette wheel, what is the probability that it would land on a green pocket

Answers

You have about 5.23% chance to land in a green pocket. You can find this by dividing 2/38 or the questioned amount by the total amount of options.
Final answer:

The probability of an American roulette wheel landing on a green pocket is 1/19, which is calculated by dividing the number of green pockets by the total number of pockets on the roulette wheel.

Explanation:

The student is asking about the probability of a specific outcome in a random event, specifically, the likelihood of landing on a green pocket in an American roulette game. To find this probability, we need to look at the total number of pockets and how many of them are green. With 38 total pockets and 2 being green, the probability that the roulette wheel will land on a green pocket is calculated by the ratio of green pockets to total pockets.

To calculate it: Probability = Number of green pockets / Total number of pockets = 2 / 38 = 1/19

This simple division computes the likelihood of a single spin resulting in a green pocket landing. Importantly, this calculation assumes each pocket has an equal chance of being landed on and that there are no biases in the wheel.

Solve each data for x: (a) a rectangle has (2x + 1) and (x +2) as length and width. Its area is 77 (b.) a triangle has (2x+2) and (x+3) as base and height. Its area is 35

Answers

area of a rectangle: A= Length*width
(2x+1)(x+2)=77
2x^2+4x+x+2=77
2x^2+5x+2=77
2x^2+5x-75=0
(x-5)(2x+15)=0
x=5 or x=-7.5
Length cannot be negative, so x=5 only
the length is 11, the width is 7
Next, let's look at the triangle.
Area of a triangle: A=1/2 of base*height
(1/2)(2x+2)(x+3)=35
2x^2+8x+6=70
2x^2+8x-64=0
x^2+4x-32=0
(x-4)(x+8)=0
x=4
the base is 10, the height is 7

The ordered pairs (1, 4), (2, 16), (3, 64), (4, 256), and (5, 1,024) represent a function. what is a rule that represents this function?

Answers

Try to graph where these points would fall. 

As you can already notice, the y-values are increasing exponentially. 

How would you get 4->16? 4^2
16->64? 4^3

I have attached a graph below that will help you visualize this. 

Final answer:

The rule that represents the given function with ordered pairs (1, 4), (2, 16), (3, 64), (4, 256), (5, 1,024) is f(x) = 4^(x-1), which is determined by observing the pattern of the ordered pairs.

Explanation:

Identifying the Rule of a Function

The ordered pairs (1, 4), (2, 16), (3, 64), (4, 256), and (5, 1,024) represent a function where each input from the domain is mapped to a unique output in the range. Observing the pattern of the ordered pairs, we can infer a rule that corresponds to this function. Each second element in the pair appears to be an exponentiation of 4 to the power of the first element minus one.

The general rule for this function can be expressed as f(x) = 4^(x-1). We can verify this by plugging in the values from the domain (1 through 5) into the function:

For x = 1, f(1) = 4^(1-1) = 4^0 = 1

For x = 2, f(2) = 4^(2-1) = 4^1 = 4

For x = 3, f(3) = 4^(3-1) = 4^2 = 16

For x = 4, f(4) = 4^(4-1) = 4^3 = 64

For x = 5, f(5) = 4^(5-1) = 4^4 = 256

Therefore, the rule representing this function is f(x) = 4^(x-1).

The solution to ...

Hello Ashley!

This is an isosceles triangle. How do we know? Well, the two little bar they put means that it is isosceles. When you add all the angles together, you MUST find them equal to 180. Another you need to keep in mind is that the angle that are face to face with each other are ALWAYS equal.

Too much talking...we gonna solve the problem.

x + x + 72 = 180
2x + 72 = 180
2x = 180 - 72
2x = 108
x = 108/2
x= 54
That's the answer .

---------------------
What did we say earlier? We said that when we add all the angles together we MUST find them equal to 180. So, we gonna replace x by 54

54 + 54 + 72  = 180
180 = 180
So.. yes we got it right!

54 is the correct answer.

Good luck with your studies!



Q=p(r+s) solve for p

Answers

Q = p(r + s)
Use the distributive property
Q = pr + ps
Q = p x r + p x s
Q = p x p + r x s
Q = p^2 + rs
Subtract rs from both sides
Q - rs = p^2
Square root both sides
sqrt Q - rs = p
Q=p(r+s)
Q/(r+s)= p(r+s)/(r+s)
ANSWER
Q/(r+s) = P

An angle measures 24° more than the measure of a complementary angle. what is the measure of each angle?

Answers

****hope this helps****

The angle which is 24° more than the measure of its complementary angle is 66°.

What are complementary angles?

Two angles whose sum is equivalent to 90 degrees are called complementary angles. Mathematically -

∠x + ∠y = 90°

Assume that the angle which is 24° more than the measure of its complementary angle be [x].

Then, we can write -

x + 24 = 90

x = 90 - 24

x = 66°

Therefore, the angle which is 24° more than the measure of its complementary angle is 66°.
