The probability of getting exactly 1 red is 60/121
What is probability?Probability theory, a branch of mathematics concerned with the analysis of random phenomena.
There is a bag filled with 5 blue and 6 red marbles.
A marble is taken at random from the bag, the color is noted and then it is replaced. Another marble is taken at random.
It is required to find the probability of getting exactly one red marble.
Now, the red marble can occur on the first draw or the second draw.
The probability of getting exactly 1 red marble from the first draw will be,
P(1) = 6/11 x 5/11
p(1) = 30/121
The probability of getting exactly 1 red marble from the second draw will be,
P(2) = 6/11 x 5/11
p(2) = 30/121
So, the total probability of the event will be,
P = P(1) + P(2)
P = 30/121 + 30/121
P = 60/121
hence, the probability of getting exactly 1 red is 60/121

What do you understand by irrational number?In mathematics, all real numbers that are not rational are referred to as irrational numbers (from the in- prefix assimilate to ir- (negative prefix, privative) + rational). In other words, it is impossible to describe an irrational number as the ratio of two integers. When there is an irrational relationship between the lengths of two line segments, the line segments are also said to be incommensurable. This means that there is no length, no matter how short, that could be used to express the lengths of the two supplied segments as integer multiples of itself.
In short, an irrational number is a real number that cannot be expressed as a fraction or ratio of two integers. Examples of irrational numbers include pi (3.14159), the square root of 2 (1.41421356237...), and e (2.718281828459045...).

A country road is 27 miles long and goes all the way around a lake, connecting the six cottages that
are next to the lake. Two of the cottages are 1 mile apart (along the road). Two cottages are 2 miles
apart, two are 3 miles apart, two are 4 miles apart..... two are 25 miles apart, and two are 26 miles
apart. How are the cottages distributed along the road? Find a second way to distribute
them. Explain your thinking.
Answer:
Step-by-step explanation:
The total length of the road is 27 miles, and since each cottage is separated from its neighbor by a distance of 1, 2, 3, 4, ..., 25, or 26 miles, the total length of the road occupied by these distances must sum to 27 miles. This is because the road connects the six cottages.
One possible distribution is:
Cottage 1 and 2 are 1 mile apart.
Cottage 3 and 4 are 2 miles apart.
Cottage 5 and 6 are 3 miles apart.
Cottages 1 and 3 are 4 miles apart.
Cottages 2 and 4 are 5 miles apart.
Cottages 3 and 5 are 6 miles apart.
Cottages 4 and 6 are 7 miles apart.
...
Cottages 1 and 6 are 25 miles apart.
Cottages 2 and 5 are 26 miles apart.
A second possible distribution can be obtained by reversing the order of the distances between the cottages. That is:
Cottages 2 and 5 are 26 miles apart.
Cottages 1 and 6 are 25 miles apart.
Cottages 4 and 6 are 7 miles apart.
Cottages 3 and 5 are 6 miles apart.
Cottages 2 and 4 are 5 miles apart.
Cottages 1 and 3 are 4 miles apart.
Cottage 5 and 6 are 3 miles apart.
Cottage 3 and 4 are 2 miles apart.
Cottage 1 and 2 are 1 mile apart.
There may be other possible distributions, but these two demonstrate that there are multiple ways to arrange the distances between the cottages while still satisfying the constraint that the distances must sum to 27 miles.

Can someone please explain what a Function is to me?
A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
Salut/Hello!
Definition of a function: In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
To make it more simple imagine a empty box with 2 holes ( one at the top and the other at the bottom ) and you insert a ball in the top hole and it falls thru the bottom hole.
When the ball falls inside the box (function) thru the top hole it'll be called
"input ball". The inside of the box can be called "function box:"
So once the ball falls out of the box thru the bottom hole it'll be called "output box(ball)".
Example: (using the image)
1. In this diagram of a function we have the domain X = {A,B,C} and codomain Y = {1,2,3} and it's defined with the set of ordered pairs {(A, 2), (B, 1), (C, 3)} and the set range is {A,B,C}
2. In this diagram of a function we have the domain A = {1,2,3} and codomain B = {X,Y,Z} and it's defined with the set of ordered pairs {(1, Y), (2, Y), (3, Z)} and the set range is {Y,Z}
3. In this diagram, representing the set of pairs {(1,D), (2,E), (2,F)} does not define a function because 2 is the first element in more than one ordered pair, but also because 3 is not the first element of any ordered pair.
Answer:
Relation 1: Function
Relation 2: Not a function (-8 is the first element in more than one ordered pair)
Relation 3: Function (a function can contain ordered pairs that include the same value for both the domain and codomain)
Relation 4: Not a function (5 is the first element in more than one ordered pair)

Let P(t)=36(1−e^(−kt))+56
represent the expected score for a student who studies t
hours for a test. Suppose k=0.24
and test scores must be integers.
The highest integer that the student can possibly score is given as follows:
92.
If the student does not study, the grade that he should expect is of:
56.
What is the exponential function?The exponential function for this problem is defined as follows:
P(t) = 36(1 - e^(-0.24t)) + 56.
In which:
t is the number of hours studied for the test.P(t) is the expected grade.The highest grade is for large values of t, meaning that e^(-0.24t) = 0, and thus:
P(t) = 36 + 56
P(t) = 92.
If the student does not study, we have that t = 0, hence the grade is given as follows:
P(0) = 36(1 - e^(-0.24 x 0)) + 56
P(0) = 0 + 56
P(0) = 56.

How long does it take a 2000-Kg car to stop from a velocity of 35 m/s if a braking force of 4000 Newtons is used?
Answer:
To find the time it takes for a car to stop from a velocity of 35 m/s using a braking force of 4000 N, we can use the following formula:
vf = vi + at
where
vf = final velocity (0 m/s in this case, since the car is stopping)
vi = initial velocity (35 m/s)
a = acceleration, which can be calculated as a = F/m, where F is the braking force (4000 N) and m is the mass of the car (2000 kg)
t = time
Rearranging the formula:
t = (vf - vi)/a = (0 - 35) / (4000 / 2000) = (35) / (2) = 17.5 s
Answer:
It takes the car 17.5 seconds to stop from a velocity of 35 m/s with a braking force of 4000 N.
What is the difference between the tallest height of 4 2/4 and the shortest height of 4 1/4? Explain.
The difference difference between the tallest height of 4 2/4 and the shortest height of 4 1/4 is of:
1/4.
How to obtain the difference between the heights?The heights are given as follows:
Tallest height: 4 and 2/4 -> as a fraction: (4 x 4 + 2)/4 = 18/4.Shortest height: 4 and 1/4 -> as a fraction: (4 x 4 + 1)/4 = 17/4.The difference between these heights is given by the subtraction of the tallest height by the shortest height, hence:
18/4 - 17/4 = 1/4.
The fractions have the same denominator, hence we just subtract the numerators.
