COORDINATE GEOMETRY Find the perimeter and area of each figure with the given vertices. 20. D(-2,-2), E(-2, 3), and F(2, -1)​

Answers

Answer 1

Step-by-step explanation:

Find the sides and perimeter:

DE = 3 - (-2) = 5EF = [tex]\sqrt{(2+2)^2+(-1+2)^2} =\sqrt{17}[/tex] ≈ 4.1DF = [tex]\sqrt{(2+2)^2+(3+2)^2} =\sqrt{41}[/tex] ≈ 6.4

Perimeter:

P = 5 + 4.1 + 6.4 = 15.5 units

Find the area using shoelace formula:

A = 1/2|(x₁y₂ + x₂y₃ + x₃y₁) - (y₁x₂ + y₂x₃ + y₃x₁)|=1/2|(-2*3 + -2* -1 + 2* -2) - (-2* -2 + 3*2 - 1* -2)|=1/2|(-6 + 2 - 4) - (4 + 6 + 2)| =1/2|-8 - 12| =1/2(20) = 10 units²

In a statewide lottery, one can buy a ticket for $1. With probability .0000001, one wins a million dollars ($1,000,000), and with probability .9999999 one wins nothing ($0). Let Y denote the winnings from buying one ticket. Construct the probability distribution for Y. Show that the mean of the distribution equals .10, corresponding to an expected return of 10 cents for the dollar paid.

Answers

Using the expected value, it is found that the mean of the distribution equals $0.1.

The expected value, which is the mean of the distribution, is given by each outcome multiplied by it's probability.

The probabilities of each outcome are:

.0000001 probability of earning $1,000,000..9999999 probability of earning $0.

Thus, the mean is given by:

[tex]E(Y) = 0.0000001(1000000) + 0.9999999(0) = 0.1[/tex]

Thus showing that the expected value is $0.1.

four times the sum of a number and 7 is 44 less than the number

Answers

Answer:

The number is 17.

Step-by-step explanation:

Let x be the unknown number.

4 times the sum of a number plus 7 would be

4x + 7

44 less than the unknown number (x) would be

x - 44

Now we connect everything.

4x + 7 = x - 44

4x - x = -44 - 7

3x = -51

x = -17

The algebraic representation of the expression is 4(x + 7)  = x - 44

How to determine the algebraic representation of the expression

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

four times the sum of a number and 7 is 44 less than the number

By definiton:

Sum means plus

Less than means minus

Using the above as a guide, we have the following:

4 * (x + 7) = x - 44

So, we have

4(x + 7)  = x - 44

17. The sum of a three-digit number
and a one-digit number is 642.
The product of the numbers is
5,072. What are the numbers?

Answers

Answer: 2  and 321 or  3  and 214

Step-by-step explanation:

One number is between 200-225.

Now, back up just a bit.  The product of the two numbers is 642.  Product comes from multiplying the two numbers.  So, if we divide 642 by the number that is between 200-225, we will get the other number.

 So, divide 200 into 642 and get 3 with a remainder of 42

     divide 225 into 642 and get 2 with a remainder of 192

This means that the other number must be either 2 or 3.  (note: this is because dividing by 200 gives the biggest value it could be and dividing by 225 gives the lowest value it could be -- think about sharing a bag of candy, dividing it between 2 friends gets each person the most candy and dividing it between more friends (3) gives each person less candy).

Well. if the other number is either 2 or 3, and the product of the two numbers is 642, the numbers must be either: 2  and 321 or  3  and 214

Answers

Answer:

2 other people.

Step-by-step explanation:

First, find a common denominator. Note that what you do to the denominator, you must do to the numerator:

[tex]\frac{1}{4} * \frac{3}{3} = \frac{3}{12}[/tex]

Each other person implies that she will reserve a piece of chocolate for herself, so you will subtract 1:

the sum of two consecutive integers is 299. find the integers.​

Answers

THANK YOU.

TEDDYLOVER

Since the sum of two consecutive integers is 299, the integers are 149 and 150

What are integers?

Integers are posiive or negative whole numbers.

Since the sum of two consecutive integers is 299. To find the integers., we proceed as follows.

Since the sum of two consecutive integers is 299.

Let the two consecutive integers be n and n + 1.

Since the sum of two consecutive integers is 299, we have that

n + n + 1 = 299

Adding like terms, we have that

n + n + 1 = 299

2n + 1 = 299

Subtracting 1 from both sides of the equation, we have that

2n + 1 = 299

2n + 1 - 1 = 299 - 1

2n + 0 = 298

2n = 298

Dividing both sides of the equation by 2, we have that

2n = 298

n = 298/2

n = 149

So, n + 1 = 149 + 1 = 150

So, the integers are 149 and 150
