Step-by-step explanation:
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.
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.

Answer:
[tex]\rm x=7[/tex]
Step-by-step explanation:
Given equation:
[tex]\rm 5x-2+x=9+3x+10[/tex]
Collect like terms:
[tex]\implies \rm 5x+x-2=3x+10+9[/tex]
Combine like terms:
[tex]\implies \rm 6x-2=3x+19[/tex]
Add 2 to both sides:
[tex]\rm \implies 6x-2+2=3x+19+2[/tex]
[tex]\rm \implies 6x=3x+21[/tex]
Subtract 3x from both sides:
[tex]\rm \implies 6x-3x=3x+21-3x[/tex]
[tex]\implies \rm 3x=21[/tex]
Divide both sides by 3:
[tex]\implies \rm 3x \div 3=21 \div 3[/tex]

Answer:
The answer is -2.25
Answer:
-2.25
Step-by-step explanation:
1. Between each integer, there are four sections. That means that each section is 1/4, or 0.25
2. Starting at -2, we're going to the left by 0.25 to point B. This can be written as an equation of: [tex]-2 - 0.25 = B[/tex]
3. Now, since -2.25 is the result when subtracting 0.25 from -2, -2.25 is the decimal value positioned at point B.

s = d / t
d = s * t

evelin had 1/4 of piece of choclate leftover. she wanted to share it which n other people. if each other person got 1/12 of a piece of choclate, how many people did she share with ?
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:
[tex]\frac{3}{12} - \frac{1}{12} = \frac{2}{12}[/tex]
She will share with 2 other people.

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?
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

The scale on a map says that 6cm represents 8km What is the actual number of kilometers that is represented by 8cm
If a map has a scale where 6 cm represents 8 km, using proportion, the actual distance in km that 8 cm represents is: 10.7 km.
Given the following:
Scale of map: 6 cm represents 8 kmRequired:
Actual distance that 8 cm on the map represents.
We would apply our knowledge of proportion to solve this problem as follows:
Let x represent the actual distance we are looking.
Thus, the following proportion can be made:6 cm = 8 km
8 cm = x km
Cross multiply[tex]x = \frac{8 \times 8}{6} \\\\x = 10.7 $ km[/tex]
Therefore, if a map has a scale where 6 cm represents 8 km, using proportion, the actual distance in km that 8 cm represents is: 10.7 km.

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
