Answer:
The function is:
[tex]f(x) = x - 0.15x[/tex]
Can also be written as:
[tex]Sale = Original - 0.15(Original)[/tex]
Step-by-step explanation:
Given that the sale percentage is 15%
In general, the sale price is calculated by finding the discount according to discount percentage and then subtracting the discount from original price.
Given that x is the original price
Then the discount will be:
[tex]Discount = Original Price * 0.15\\Discount = 0.15x[/tex]
The sale price will be:
[tex]Sale Price = Original\ Price - 0.15(Original\ Price)\\[/tex]
As x is the original price
[tex]f(x) = x - 0.15x[/tex]
Can also be written as:
[tex]Sale = Original - 0.15(Original)[/tex]

5(4 • 3 + 3 • 4)=
480
300
120
Answer:
Step-by-step explanation:
Our given equation is 5 (4 × 3 + 3 × 4)
Using The Order of Operations (AKA): PEMDAS, we need to solve this.
The "P" stands for parentheses. We do have them, so we need to solve the operations inside of them.
We don't have any parentheses inside.
The "E" stands for exponents. We don't have any, so we need to move on.
The "M" stands for multiplication. We have two multiplication symbols, so we need to solve them.
1. 5 (4 × 3 + 3 × 4)
2. 5 (12 + 3 × 4)
3. 5 (12 + 12)
The "D" stands for division. We don't have any of them, so we need to move on.
The "A" stands for addition. We have one of them, so we need to solve.
4. 5 (12 + 12)
5. 5 × 24
Now that we only have the operation 5 × 24, we can go ahead and solve.
6. 5 × 24 = 120
So now we know that when using The Order of Operations to solve the equation: 5 (4 × 3 + 3 × 4) results in a 120.
Remember this; This is The Order of Operations/ PEMDAS expression:

The y-intercept of an equation is a point where the graph of the equation intersects the Y-axis. There are several ways to find the y-intercept of an equation, depending on the starting information you have.
How to find the Y-Intercept from the Slope and Point.
Write down the slope and point. The slope or "rise over run" is a single number that tells you how steep the line is. This type of problem also gives you the (x, y) coordinate of one point along the graph. Skip to the other methods below if you don't have both these pieces of information.
Example 1: A straight line with slope 2 contains the point (-3,4). Find the y-intercept of this line using the steps below.Mark owns a personal training business. He makes a total of $500 for every 3 clients he acquires. How much money will 21 clients bring in?

A boy was asked to multiply a number by 7/8
instead he divided the number by 7/8 and got the
result 15 more than the correct result The number is?
Answer:
So first you would do 15 x 7/8 which would get you 13.12500 but round it and you would get 13.125 as the original number. If you were trying to get the number it first asked you would do 15 x 13.125 = 196.87500, round that and you would get 196.875.

Tamika has two bags of trail mix. Each has a combination of 60 pieces of fruit and nuts. Ratio of fruit to nuts in the first bag:3 5 Ratio of fruit to nuts in the second bag:7 10 Which bag has more fruit? Use the ratios to justify your answer. The first bag, because the ratio is greater. The first bag, because the ratio is smaller. The second bag, because the ratio is greater. The second bag, because the ratio is smaller.
Answer:
the second bag because the ratio is greater
Step-by-step explanation:
Bag1
fruits 3 : 5 nuts so 3+5=8 and 60/8=7.5 but 7.5*3=22.5
ratio is 3/5=0.428
Bag2
fruits 7 : 10 nuts so 10+7=17 and (60/17)*7 ≈ 24.7
ratio is 7/10=0.7
Answer:
The second bag, because the ratio is greater.

Suppose the total number of acres of genetically modified crops grown in developing countries from 2006 through 2012 was changing at the rate of R′(t)=2.613t2−17.7t+41.38 (0 ≤ t ≤ 6). The total number of acres of such crops grown in 1997 (t=0) was 18.1 million acres. How many acres of genetically modified crops were grown worldwide in 2012?
Answer:
The number of acres of genetically modified crops were grown worldwide in 2012 is approximately 529.39 million.
Step-by-step explanation:
Note: There are mistakes in this question particularly in the years and the rate of change. The question is therefore correctly stated before answering the question as follows:
Suppose the total number of acres of genetically modified crops grown in developing countries from 2006 through 2012 was changing at the rate of R′(t) = 2.613t^2 − 17.7t + 41.38 (0 ≤ t ≤ 6). The total number of acres of such crops grown in 2006 (t=0) was 18.1 million acres. How many acres of genetically modified crops were grown worldwide in 2012?
The explanation to the answer is now given as follows:
From the question, we are given:
R′(t) = 2.613t^2 - 17.7t + 41.38 ................................... (1)
Since t = 0 corresponds to 2006; by counting from 2006 to 2012, it implies that t = 6 corresponds to 2013.
Substituting t = 6 into equation to obtain the rate of change in 2012, we have:
R′(6) = (2.613* 6^2) - (17.7 * 6) + 41.38
R'(6) = 29.248
The number of acres of genetically modified crops were grown worldwide in 2012 can therefore be calculated as follows:
Number of acres grown worldwide in 2012 = Number of acres grown worldwide in 2006 * R'(6) ......................... (2)
Where;
Number of acres grown worldwide in 2006 = 18.1 million acres
R'(6) = 29.248
Substituting the values into equation (2), we have:
Number of acres grown worldwide in 2012 = 18.1 * 29.248 = 529.3888 million
Approximating to 2 decimal places, we have:
Number of acres grown worldwide in 2012 = 529.39 million
Therefore, the number of acres of genetically modified crops were grown worldwide in 2012 is approximately 529.39 million.

y>-3x+1
How do I graph this
Answer:
The graph of y>-3x+1 through the points (0,1) and (1,-2)
Step-by-step explanation:
y=3x+1 is in the slope intercept form
y=mx+b
m = the slope in this case 3
b = the y intercept in this case 1.
Think of b the y intercept as the beginning this is where to start the graph.
So start with (0,1) the y intercept and make the first point at (0,1)
Think of m ( the slope) as the mountain slope, This is the angle of the slope of the line
So in this case go up three on the y axis and over 1 on the x axis.
make the next point at 1 + 3 = 4 for the y value and 0 + 1 = 1 for the x value. Make the next point at ( 1, 4)
Now connect the points. creating the line

Erik Red is a player for the Arizona Snowflakes in the National Foosball League. The league has 25 teams, each with 73 players. Every week, 8 players per team are chosen for random drug testing.
A) What is the probability that Erik Red is chosen for random drug testing in a specified week of the foosball season?
B) What is the probability that Erik Red is chosen for random drug testing at least 5 times in the first 9 weeks of the foosball season?
C) What is the expected number of players who are chosen for random drug testing at least 4 times in the first 9 weeks of the foosball season?
D) Let Y be the number of players who are chosen for random drug testing at least 4 times in the first 9 weeks of the foosball season. What is the maximum possible value of Y, i.e., the largest k such that P(Y=k) > 0?
Answer:
8/73
0.10959
21 players
Step-by-step explanation:
Given that:
Number of teams = 25
Number of players per team = 73
Number of players chosen for drug testing = 8
A) What is the probability that Erik Red is chosen for random drug testing in a specified week of the foosball season?
Number chosen per team / number of players per team
8 / 73 = 0.10959
B) What is the probability that Erik Red is chosen for random drug testing at least 5 times in the first 9 weeks of the foosball season?
P( being chosen at least 5 times)
USing binomial. Distribution
P(X =x) = nCr * p^x * (1-p)^n-x
To save computation time, we can use the binomial distribution calculator :
P(x≥5):p(x = 5) + p(x = 6) + p(x =7) + p(x = 8) +. P(x = 9) = 0.00136
C) What is the expected number of players who are chosen for random drug testing at least 4 times in the first 9 weeks of the foosball season?
Number who are chosen atleast 4 times :
P(x ≥ 4) = p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7) + p(x = 8) +. P(x =9) = 0.0115
P(x ≥ 4) * number of players per team * nunber of teams in league
0.0115 * 73 * 25 = 20.9875
= 21 players
D) Let Y be the number of players who are chosen for random drug testing at least 4 times in the first 9 weeks of the foosball season. What is the maximum possible value of Y, i.e., the largest k such that P(Y=k) > 0?

Do the Louisiana State Flag have a line of symmetry?
Answer: No it does not
Well, first you can search up a picture of the Louisiana State Flag if you don't know what it looks like. In case you don't, it looks like this.
The Louisiana State Flag does not have a line of symmetry because the bird's head is facing in one direction. If you split the state flag in half, both sides would not be similar.
