If f(x) = 0.41x is a function that represents the cost to mail
x number of letters, what is a reasonable domain for f?
O all real numbers
o all real numbers greater than 0
O the set of all whole numbers
o the set of all integers
Answer:
B
Step-by-step explanation:
The domain of the function 'f' represents the set of all whole numbers.
What is a function?A function is a relation between two sets. One set is called domain of the function and the other one is called range range of the function.
Given function is: f(x) = 0.41x.
f(x) represents the cost of mail.
Here, x represents the number of letters in the mail.
It can't be real numbers because, real numbers consist of negative numbers, fractions, etc.
It can not be integers, real numbers consist of negative numbers.
Therefore, the domain of must be all whole numbers.

Most of the math we learn in school do you actually think that we use half of it?
Also tell me how to give brainliest in your answer so I can give full points
please actually answer the question this is worth 50 points and i dont want to waste them
Answer:
Some subjects are more important than others. You have to be working in a field where the concepts you learn in school.
I'd say that everything you learn in middle school and Algebra 1 + 2 , maybe a little of geometry you'll use at some point in your life.
Step-by-step explanation:
Everyone has asked themselves: When will I use math? Well, hundreds of careers use skills learned in high school math on a daily basis. The truth is virtually every career you could choose will build on the basic skills learned in High School Math.
But there are a number of craft and fine arts careers that do not require math skills or involve using them regularly, such as being a painter or sketch artist. Craft and fine artists produce original works that will be displayed or sold, and they may work with a range of materials, such as paint, glass or ink.
To conclude I might say that math is important and everyone should know more than just some basic skills in math.Life is long and sometime harsh for most of us and not always we get in life what we want,probably we will end up doing a job that it was not our dream job.
Or our preferences might change depending on different aspects of life.So knowing a 'little bit' from every subject we do in school is not a bad thing,at the end we know all that greatest things are achived will a hard work!So we should learn as much as we can! Math especially!
And all our hard work will be payed at the end,just remember this!

Solve the multistep inequality.
4x + 3 < 5x − 6
Answer:
x > 9
Step-by-step explanation:
Isolate the variable, x. Treat the < as an equal sign, what you do to one side, you do to the other.
First, subtract 5x and 3 from both sides of the inequality:
4x (-5x) + 3 (-3) < 5x (-5x) - 6 (-3)
4x - 5x < -6 - 3
-x < -9
Isolate the variable, x. Divide -1 from both sides. Note that when you divide or multiply by a negative number, you must flip the sign:
(-x)/-1 < (-9)/-1
x < -9/-1
x > 9
x > 9 is your answer.

Answer:
x > 9
Step-by-step explanation:
4x + 3 < 5x − 6
-x < -9
x > 9
Baking a tray of chocolate chip cookies takes three cups of milk and two cups of flour. Baking a tray of oatmeal raisin cookies takes one cup of milk and four cups of flour. The baker has 9 cups of milk and 16 cups of flour available. He makes $2.50 profit per tray of chocolate chip cookies and $2 profit per tray of oatmeal raisin. How many trays of each type of cookies should be make to maximize his profit?
Step-by-step explanation:
this is a linear programming problem.
the objective is to maximize profit
let the chocolate be x
and cookies be y
Maximize
2.5x+2y=P
constraint milk
3x+y=9------------------1
constraint flour
2x+4y=16----------------2
solving 1 and 2
3x+y=9
2x+4y=16
multiply 1 by 2 and 2 3 to eliminate x we have
6x+2y=18
6x+12y=48
-0-10x=-30
10y=30
y=30/10
y=3
put y= 3 in eqn 1 we have
3x+3=9
3x=9-3
3x=6
x=6/3
x=2
two trays of chocolate
three trays of cookies
2.5x+2y=P
2.5(2)+2(3)=P
5+6=P
P=$11
On June 19, NoteQuest Inc. instituted a 3-for-2 split. At that time Keisha owned 205 shares of that stock. The price per share was
$33.99. After the split, Keisha received a check for a fractional part of a share. What was the amount of that check?
Answer:
$11.33
Step-by-step explanation:
Keisha will own 307 shares after the split. and the amount of check is 11 dollar.
Given that, NoteQuest Inc. instituted a 3-for-2 split. At that time Keisha owned 205 shares of that stock. The price per share was
$33.99.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Here, 3+ 2 = 5
Now, let x be the number of shares post split
Then;
3/2 = x/205
x = 3/2 (205)
x = 615/2 = 307.5
Therefore, Keisha will own 307 shares after the split.

THIS IS STATISTICS** Are physically fit people less likely to die of cancer? An article in the May 2002 issue of "Medicine and Science in Sports and Exercise" reported results of a study that followed 25,892 men aged 30 to 87 for 10 years. The most physically fit men had a 55% lower risk of death from cancer than the least fit group. What is the population of interest and the sample in this scenario? Write your response using complete sentences. plz help
Answer:
In this case the population of interest is the set of all men aged 30 to 87.
In this case the sample is the set of 25,892 men aged 30 to 87.
Step-by-step explanation:
A population is the set of all the data that can be collected and from which a smaller set of data is drawn for further examination. A population may denote to a group of individuals, articles, trials or measurements. A population can thus be called as a collection of information regarding subjects combined together by a common characteristic.
In this case the population of interest is the set of all men aged 30 to 87.
A sample denotes a smaller, controllable form of a larger cluster. It is a subset comprising of the characteristics of a bigger population. Samples are used in statistical experiments when the population under consideration is too large for the test to include all the members.
In this case the sample is the set of 25,892 men aged 30 to 87.
After some bad news (due to a revolutionary but ultimately doomed process for making toast in a microwave oven), stock in Seraj Food Industries fell by 40%, to $324 a share. What was the original price of a share? Thank you so much i'll mark brainliest!
Answer:
Around $650
Step-by-step explanation:
The original price of a share is $540.
Given that, Seraj Food Industries fell by 40%, to $324 a share.
What is the percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
Let the original price of share be x.
x - 40% of x = 324
⇒ x - 40/100 × x = 324
⇒ x - 0.4x = 324
⇒ 0.6x = 324
⇒ x = 324/0.6
⇒ x = 540
Therefore, the original price of a share is $540.

second day by selling 4 adult tickets and 5 child tickets. What is the price each of one adult
ticket and one child ticket?
Answer:
x+y=4+8=12
$12 for one of each
or if you mean indivually (the wording confused me)
$4 for child, $8 for adult
Step-by-step explanation:
x=adult
y=child
2x+10y=56
4x+5y=52
iin order to be able to subtract values and find x and y im going to multiply 4x+5y=52 by two and get 8x+10y=104
8x+10y=104
-2x+10y=56
6x=48 divide each side by 6
x=8
plug 8 back into an equation to find cost of y
2(8)+10y=56

A pet store sells mice, reptiles, and birds.
Let event A = A customer buys a mouse.
Let event B = A customer buys a bird.
What does P(A or B) = 0.25 mean in terms of this problem?
A. Buying a mouse and buying a bird are mutually exclusive events.
B. The probability that a customer buys neither a mouse nor a bird is
25%.
C. The probability that a customer buys both a mouse and a bird is
25%.
D. The probability that a customer buys either a mouse or a bird is
25%.
The correct answer is: The probability that a customer buys either a mouse or a bird is 25%.
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.
Given that, a pet store sells mice, reptiles, and birds,
Let event A = A customer buys a mouse.
Let event B = A customer buys a bird.
We need to tell that,
What does P(A or B) = 0.25 mean in terms of this problem,
So, here the statement given is saying that the 0.25 is the probability that a customer will buy either a mouse or bird,
Hence, the correct answer is: The probability that a customer buys either a mouse or a bird is 25%.
