The probabilities and the odds are P(E) = 4/9, P(E) = 1/8 and o(E) = 1 : 7

Probability P(E)

From the question, we have the following notation that can be used in our computation:

Odds, o(E) = 4 : 5

Using the above as a guide, we have the following probability equation

P(E) = 4/(4 + 5)

Evaluate

P(E) = 4/9

Probability P(E)

Here, we have

Odds, o(E) = 7 : 4

Using the above as a guide, we have the following probability equation

P(E) = 7/(7 + 4)

Evaluate

P(E) = 7/11

Odds (E)

Here, we have

P(E) = 1/8

Using the above as a guide, we have the following probability equation

o(E) = P(E) : 1 - P(E)

So, we have

o(E) = 1/8 : 7/8

Evaluate

o(E) = 1 : 7

This is to show that we can use a normal equation then change the digits to get an answer.

Note that as x gets larger, y gets smaller, but the product xy remains constant at 192.

In mathematics, a function is a relationship between two sets, called the domain and the range, such that each element of the domain corresponds to exactly one element of the range. A function takes an input value (or values) and produces an output value (or values) according to a specific rule or formula. The input values are the domain of the function, and the output values are the range of the function. Functions can be represented using equations, graphs, tables, or verbal descriptions. They are used to model relationships between variables in various fields of mathematics, science, engineering, economics, and many other areas.

Here,

If x and y vary inversely, this means that their product is a constant. We can use this fact to find the constant of proportionality k as follows:

k = xy

If we know that y is 24 when x is 8, we can substitute these values into the equation above to solve for k:

k = xy

= 8(24)

= 192

Now we can use this value of k to write the inverse variation function:

xy = 192

or

y = 192/x

To sketch a graph of this function for x > 0, we can plot a few points and connect them with a smooth curve. Here are some points we can use:

(x, y)

(2, 96)

(4, 48)

Step-by-step explanation:

The function (f) gives us the total amount of money Guadalupe makes in a week, in terms of the number of hours she works as a waitress (x) is h(x) = -4.75x + 495

Let's start by defining the functions:

f(x) = amount of money Guadalupe makes as a waitress for x hours

g(x) = amount of money Guadalupe makes as a tutor for the remaining (30 - x) hours, given that she has already worked x hours as a waitress

h(x) = total amount of money Guadalupe makes in a week, given that she has worked x hours as a waitress and (30 - x) hours as a tutor.

To find the amount of money Guadalupe makes as a waitress for x hours, we can simply multiply her hourly wage ($11.75) by the number of hours she works:

f(x) = 11.75x

To find the amount of money Guadalupe makes as a tutor for the remaining (30 - x) hours, we can use the same approach, but with her tutor hourly wage ($16.50):

g(x) = 16.5(30 - x)

Note that we are using (30 - x) instead of just x, since the number of hours she can work as a tutor is limited by the number of hours she has already worked as a waitress.

Finally, to find the total amount of money Guadalupe makes in a week, we simply add up the amount of money she makes as a waitress and the amount of money she makes as a tutor:

h(x) = f(x) + g(x)

h(x) = 11.75x + 16.5(30 - x)

h(x) = 11.75x + 495 - 16.5x

h(x) = -4.75x + 495

So the function h(x) gives us the total amount of money Guadalupe makes in a week, in terms of the number of hours she works as a waitress (x).

Answer:

An arithmetic sequence with a common difference of −2 is 20,18,16,14,12..

Step-by-step explanation:

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is same. Here, the common difference is -2, which means that each term in the sequence is obtained by subtracting 2 from the previous term.

To find the arithmetic sequence with a common difference of -2, you can start with an first term and then subtract 2 successively to find the subsequent terms.

Let the initial term is 20. Subtracting 2 from 20, we get 18. Subtracting 2 from 18, we get 16. Continuing this pattern, we subtract 2 from each subsequent term to generate the sequence. The arithmetic sequence with a common difference of -2 starting from 20 is

20,18,16,14,12

In this sequence, each term is obtained by subtracting 2 from the previous term, resulting in a common difference of -2.

Answer:

Let's start by assigning a variable to Susan's present age. Let's call it "x".

According to the problem, in seven years, Susan will be "x + 7" years old.

Three years ago, Susan was "x - 3" years old.

The problem tells us that Susan will be 2 times as old in seven years as she was 3 years ago. So we can set up the following equation:

x + 7 = 2(x - 3)

Now we can solve for x:

x + 7 = 2x - 6

x = 13

Therefore, Susan's present age is 13 years old.

Let's assume Susan's present age is "x" years. According to the information provided, "Susan will be 2 times old in seven years as she was 3 years ago."

Seven years from now, Susan's age would be x + 7, and three years ago, her age would have been x - 3. According to the given statement, her age in seven years will be two times her age three years ago:

x + 7 = 2(x - 3)

Let's solve this equation to find Susan's present age:

x + 7 = 2x - 6

Subtracting x from both sides:

7 = x - 6

Adding 6 to both sides:

13 = x

Therefore, Susan's present age is 13 years.

f the gray suitcase weighs 11 lb more than the pink suitcase, the pink suitcase weighs 5 lb than the blue suitcase, and the total of 3 suitcases is 127 lb, then the blue suitcase weighs 35.3 lb

Let the gray suitcase be represented by g

Let the pink suitcase be represented by p

Let the blue suitcase be represented by b

The gray suitcase weighs 11 lb more than the pink suitcase

g    =   p   +   11........(1)

The pink suitcase weighs 5 lb than the blue suitcase.

p   =  b  +  5

b  =  p  -  5...........(2)

Total of 3 suitcases = 127 lb

p  +  b  +  g    =  127............(3)

Substitute equations (1) and (2) into equation (3)

p  +  p  - 5 + p  +  11   =  127

3p  +  6   =  127

3p   =  127  -  6

3p   =  121

p  =  121/3

p  = 40.3 lb

Substitute p = 40.3 into equation (2)

b = p - 5

b  = 40.3  - 5

b  =  35.3

The blue suitcase weigh 35.3 lb

Answer:

the solution to the equation -2a - 6a - 9 = -9 - 6a - 2a is all real numbers, or (-∞, +∞).

Step-by-step explanation:

To solve this equation for "a", you need to simplify and rearrange the terms so that all the "a" terms are on one side of the equation and all the constant terms are on the other side. Here are the steps:

Start by combining the "a" terms on the left side of the equation: -2a - 6a = -8a. The equation now becomes: -8a - 9 = -9 - 6a - 2a.

Combine the constant terms on the right side of the equation: -9 - 2a - 6a = -9 - 8a. The equation now becomes: -8a - 9 = -9 - 8a.

Notice that the "a" terms cancel out on both sides of the equation. This means that the equation is true for any value of "a". Therefore, the solution is all real numbers, or in interval notation: (-∞, +∞).

In summary, the solution to the equation -2a - 6a - 9 = -9 - 6a - 2a is all real numbers, or (-∞, +∞).

Answer:

1 round = 220 meter wire

2 rounds = 440 meter wire

3 rounds = 660 meter wire

Step-by-step explanation:

Given that:

Perimeter of squared garden = 220m

As the perimeter is given, the length of the wire would be calculated with it.

The length of wire to fence with 1 round = 220 * 1 = 220m

The length of wire to fence with 2 rounds = 220 * 2 = 440m

The length of wire to fence with 3 rounds = 220 * 3 = 660m

Hence,

1 round = 220 meter wire

2 rounds = 440 meter wire

3 rounds = 660 meter wire
