Which of the following is true about the lines defined by the equations 4x−2y=6 and x+2y=14? .
A.The lines share the same y-intercept.
B.Both lines intersect at point (1,−1).
C.The lines are perpendicular.
D.The lines are parallel.
Answer:
Only: C. The lines are perpendicular.Step-by-step explanation:
4x - 2y = 6 x + 2y = 14
- 2y = - 4x + 6 2y = - x + 14
y = 2x - 3 y = - ¹/₂x + 7
A.
y-intecept: (0, -3) (0, 7)
The lines don't share the same y-intercept
B.
x=1 ⇒ y = 2(1)-3 = -1 and y = -¹/₂(1) + 7 = 6¹/₂ ≠ -1
the line x+2y=14 doesn't go through point (1,−1) so the lines couldn't intersect at point (1,−1)
Slope: m₁ = 2 m₂ = -¹/₂
C.
m₁· m₂ = 2·(-¹/₂) = -1
The lines are perpendicular.
D.
m₁ ≠ m₂ The lines are not parallel
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.

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%.

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.

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

three trays of cookies
2.5x+2y=P
2.5(2)+2(3)=P

$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.

$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.

Una tableta contiene 500 mg de paracetamol, ¿cuántas tabletas se obtendrán con 5kg del mismo medicamento? xfavor ayudenme con explicación y todo lo necesito para el sabado
Answer:
Se pueden obtener 10.000 comprimidos de 500 mg de paracetamol a partir de la cantidad de 5 kg del medicamento
Step-by-step explanation:
La cantidad en masa de paracetamol en una tableta = 500 mg de paracetamol / tableta
El número de comprimidos que contienen 500 mg de paracetamol que se pueden obtener a partir de 5 kg del medicamento (paracetamol) se calcula dividiendo los 5 kg del medicamento por los 500 mg de paracetamol / comprimido de la siguiente manera;
[tex]El \ nmero \ de \ tableta = \dfrac{5 \ kg \ paracetamol}{500 \ mg \ paracetamol/tableta }[/tex]
Observamos que 5 kg = 5,000,000 mg
Por lo tanto;
[tex]El \ numero \ de \ tableta = \dfrac{5,000,000 \ mg \ paracetamol}{500 \ mg \ paracetamol/tableta } = 10,000 \ tabletas[/tex]
Por tanto, podemos obtener 10.000 comprimidos de 500 mg de paracetamol a partir de la cantidad dada de 5 kg del medicamento.

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!
