Of all airline flight requests received by a certain discount ticket broker, 60% are for domestic travel (D) and 40% are for international flights (I). Let x be the number of requests among the next three requests received that are for domestic flights. Assuming independence of successive requests, determine the probability distribution of x. (Hint: One possible outcome is DID, with the probability (.6)(.4)(.6) = .144)

Answer:
We have a binomial probability distribution, in which:
P(X = 0) = 0.064
P(X = 1) = 0.288
P(X = 2) = 0.432
P(X = 3) = 0.216
Step-by-step explanation:
For each flight, there are only two possible outcomes. Either it is for domestic travel, or it is for international travel. Flights are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Let x be the number of requests among the next three requests received that are for domestic flights.
3 flights, and 60% are for domestic travel. This means that [tex]n = 3, p = 0.6[/tex]. The probabilities are given by:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{3,0}.(0.6)^{0}.(0.4)^{3} = 0.064[/tex]
[tex]P(X = 1) = C_{3,1}.(0.6)^{1}.(0.4)^{2} = 0.288[/tex]
[tex]P(X = 2) = C_{3,2}.(0.6)^{2}.(0.4)^{1} = 0.432[/tex]
[tex]P(X = 3) = C_{3,3}.(0.6)^{3}.(0.4)^{0} = 0.216[/tex]
You typically buy all of your groceries at Grocery Mart. This week, your favorite cereal is on sale there, 4 boxes for $10. At Food Market, where you don’t typically shop, the same cereal is on sale for $2.25 a box.
Answer:
B. Food market
Step-by-step explanation:
You typically buy all of your groceries at Grocery Mart. This week, your favorite cereal is on sale there, 4 boxes for $10. At Food Market, where you don’t typically shop, the same cereal is on sale for $2.25 a box. Based on price, which is the better value option?
A.Grocery Mart
B. Food Market
Grocery market:
4 boxes for $10
Unit price = cost / quantity
= $10 / 4 boxes
= $2.50 per box
Food market:
Price per box = $2.25
The better value option based on price is food market because it cost less to buy a box of cereal than grocery mart

write an equation in point-slope form of the line that passes through the (7,-4) and has a slip of m=-6?
Answer:
y+4=-6(x-7)
Step-by-step explanation:
Point slope form is giving by the equation
y - y = m (x - x)
M being the slope and y and x being points
All you have to do is plug in your slope and point:
(y + 4) = -6 (x - 7)

Determine whether each relation is a function.
Answer:
Each relation is a function because none of the domain repeats.
The graph of a function is shown:
A coordinate grid is shown from negative 5 to 5 on both axes at increments of 1. A graph shows three straight lines. The first straight line joins ordered pair negative 3, negative 2 with negative 2, 2. The second straight line joins ordered pair negative 2, 2 with 2, 2. The third straight line joins ordered pair 2, 2 with 4, 0. The ordered pair negative 3, negative 2 is labeled as A, the ordered pair negative 2.5, 0 is labeled as B, the ordered pair negative 2, 2 is labeled as C, the ordered pair 2, 2 is labeled as D, and the ordered pair 4, 0 is labeled as E.

Answer:
A. 9(x + 8) = 9(x + 12)
Step-by-step explanation:
Simplify the probelm;
9(x + 8) = 9(x + 12)
Distribute;
9x + 72 = 9x + 108
Inverse opreations;
9x + 72 = 9x + 108
-9x -9x
72 = 108

-72 0 72
Answer: The outdoor temperature is 4 degrees below 0 or -4 degrees.
The indoor temperature is 72 degrees above 0 or 72 degrees.
Step-by-step explanation:
We use negative integer to represent loss, below , or withdrawal etc.
On the other hand we use positive integers to show gain , above , deposit etc.
Given statement : The outdoor temperature is 4 degrees below 0.
So we will represent it by -4 degrees.
The indoor temperature is 72 degrees above 0.
So we will represent it by +72 or 72 degrees.
Answer:
The outdoor temperature is 4 degrees below 0, or
✔ –4

The indoor temperature is 72 degrees above 0, or

What is a correct first step in solving the inequality –4(3 – 5x)≥ –6x + 9?
–12 – 20x ≤ –6x + 9
–12 – 20x ≥ –6x + 9
–12 + 20x ≤ –6x + 9
–12 + 20x ≥ –6x + 9
Answer:
-12 + 20x ≥ -6x + 9
Fourth choice
Step-by-step explanation:
Inequalities
We are given the inequality:
-4(3 - 5x) ≥ -6x + 9
Solving the inequality implies having x isolated on one of the sides.
We must start by removing the parentheses. It will be done by multiplying -4 by (3 - 5x). Since this operation doesn't imply multiplying all the inequality by a negative number, the sign won't be flipped:
-4*3 - (-4)5x ≥ -6x + 9
Multiplying:
-12 + 20x ≥ -6x + 9

The city is issuing bonds to raise money for a building project. You obtain a $1000 bond that pays 9% interest annually that matures in 7 years. How much interest will you earn?
Answer:
$630
Step-by-step explanation:
1000 x .09 = 90
90 x 7 = 630
The interest earned after 7 years = $630
What is Face value?Face value is a term in finance which is used to explain the nominal value of a security.
For stocks, it is defined as the cost of the stocks and it is defined as the amount paid to the holder after maturity for bonds.
In the question, is is given that $1000 bond is obtained.
Face value of the bond = $1000
The bond pays 9% interest annually.
Interest rate = 9% = 0.09
So the interest you earn annually = face value × interest rate
= 1000 × 0.09 = $90
The bond matures in 7 years.
Interest earned on maturity = 90 × 7 = $630
Hence, the amount of interest earned after 7 years will be $630.

Jennifer had some money in her pocket. She spent $1.35, which left her with $2.30. Write an equation or an inequality to find the original amount of money she had in her pocket.
Answer:
Equation: X-1.35= 2.30
Value of X: x=3.65
Step-by-step explanation:
You can choose whatever variable you want to represent the original amount of money Jennifer had in her pocket. I decided to use X as my variable.
If X represents the original amount of money Jennifer had in her pocket, then I can write this equation:
X-1.35= 2.30
Essential what this equation shows is that Jennifer spends $1.35 of what she originally has, which is x. After she spends that she's left with $2.30. This is how we solve for x, also known as the original amount Jennifer had in her pocket:
X-1.35= 2.30
(we will add 1.35 to each side because we what to balance out the equation and the inverse operation of subtraction is addition)
X= 3.65
So Jennifer originally had $3.65 in her pocket before she spent the $1.35
