Answer:
Step-by-step
If0.04a is 4% of a,
then a is 25 times larger than 0.04a (100/4 = 25).
Therefore, 0.04a is 96% smaller than a (100 - 4 = 96).
13y-8>18 ??????????????????????????????????????????????????
??????????
Answer:
y>2
Step-by-step explanation:
13y-8>18
+8 +8
13y>26
/13 /13
y>2
Step 1: Add 8 to both sides of the equation (-8+8, cancels) (18+8=26)
Step 2: Divide 13y and the result of step 1 (26) by 13
Step 3: Find answer (y>2)
I hope this helps
Answer: y > 2
Let's solve your inequality step-by-step.
13y−8>18
Step 1: Add 8 to both sides.
13y−8+8>18+8 (Addition of 8 undoes the subtraction of 8)
13y>26
Step 2: Divide both sides by 13.
13y/13 > 26/13 (Division of 13 undoes the multiplication of 13 * y)
y > 2
Suppose Martin is a very talented used car salesman.
If the probability of success is 0.43. Then the mean will be 18.49.
What is binomial distribution?Frequency distribution of the percentage of successful outcomes that might occur in a certain number of trials with the same chance of success. If X~B(n, p).
Assume Martin is an extremely capable trade-in vehicle sales rep. Whenever Martin converses with another client, there is a 43% opportunity that he persuades the client to buy one of his pre-owned vehicles. Brian, Martin's chief, is desirous that Martin sells a lot a greater number of vehicles than he does. In view of his desire, Brian establishments another standard that Martin is simply permitted to converse with 43 clients each day.
n = 43
p = 0.43
Then the mean is calculated as,

is given as {−2, −1, 0, 1, 2}. What is the range? Show your
work
The range is: {−28, −15, −2, 11, 24}
__________________________________
To find the range, substitute each 'x' from the domain into the function.
VocabularyDomain means all of the numbers that 'x' can be.
In this problem, 'x' can be −2, −1, 0, 1, and 2.Range means all of the numbers that 'y' can be.
We are looking for all of the 'y's using 'x'.A function can be an equation that relates the 'x' and 'y' variables.
We can replace 'f(x)' in an equation with the 'y' variable.In this problem, the function is f(x) = 13x −2, or y = 13x −2.Substitute into the functionLet's take each number from the domain to substitute 'x'. Remember to follow BEDMAS when solving for 'y'.
If x = −2:f(x) = 13x − 2
f(−2) = 13(−2) − 2
f(−2) = −26 − 2
f(−2) = −28
If x = −1:f(x) = 13x − 2
f(−1) = 13(−1) − 2
f(−1) = −13 − 2
f(−1) = −15
If x = 0:f(x) = 13x − 2
f(0) = 13(0) − 2
f(0) = −2
If x = 1:f(x) = 13x − 2
f(1) = 13(1) − 2
f(1) = 13 − 2
f(1) = 11
If x = 2:
f(x) = 13x − 2
f(2) = 13(2) − 2
f(2) = 26 − 2
f(2) = 24
Write the Range
To write the range, list all of the 'y' values we calculated for from least to greatest. Write the numbers inside braces (curly brackets). Writing the range or domain inside braces is called set notation.
{−28, −15, −2, 11, 24}Therefore, the range is {−28, −15, −2, 11, 24}.

What is a Coordinate Plane?A Cartesian coordinate system on a plane is a coordinate system in which each point is uniquely specified by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicularly oriented lines measured in the same unit of length.
Rene Descartes inspired the Cartesian coordinate system. It is made up of two real number lines that intersect at the origin. The plane is divided into four quadrants by two number lines that intersect at a straight angle. As seen in the attached sample, the quadrants are numbered using Roman numerals.

Three integers have a mean of 10, a median of 11 and a range of 9.
Find the three integers.
The three integers are 5, 11 and 14.
What is Mean?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
Let x₁, x₂ and x₃ be the three integers in an increasing order.
Mean = (x₁ + x₂ + x₃) / 3
(x₁ + x₂ + x₃) / 3 = 10
x₁ + x₂ + x₃ = 30
Median is the middle element when the data set is arranged in an increasing or decreasing order. Here, it is the integer x₂.
x₂ = 11
So x₁ + x₂ + x₃ = 30 becomes,
x₁ + 11 + x₃ = 30
x₁ + x₃ = 19 ⇒ x₃ = 19 - x₁
Range is the difference of the highest and lowest value.
x₃ - x₁ = 9
Substituting x₃ = 19 - x₁,
19 - x₁ - x₁ = 9
19 - 2x₁ = 9
-2 x₁ = -10
x₁ = 5
x₃ = 19 - x₁ = 19 - 5 = 14
Hence the integers are 5, 11 and 14.

Group of answer choices:
A: Book, cup, teddy bear,
B: pencil Cup, book, teddy bear,
C:pencil Pencil, book, teddy bear, cup
D:Pencil, cup, teddy bear, book
Answer:
The answer is D: Pencil, cup, teddy bear, book.
Step-by-step explanation:
The reason why the answer is D is that if you think of a pencil between a book which one would you think will be heavier??? The book. Same for the cup and the teddy bear, the teddy bear will be heavier because it's bigger and weighs more than a cup. And you have the number of grams of each object to help you with. 5 is the lowest number meaning it weighs less and will obviously be first than the others. And the highest number will go last.

Yoshi needs to find the inverse of f(x)=5x-2. what is the first step?
The first step to find the inverse of f(x) = 5x - 2 is to interchange both the x-value and y-value.
What is an inverse function?In Mathematics, an inverse function simply refers to a type of function that is obtained and generated by reversing the mathematical operation in a given function (f(x)).
In order to determine the inverse of this function f(x) = 5x - 2, we would interchange both the input value (x) and output value (y) as follows:
f(x) = 5x - 2
y = 5x - 2
x = 5y - 2
Adding 2 to both sides of the equation, we have the following:
x + 2 = 5y - 2 + 2
5y = x + 2
Dividing both sides of the equation by 5, we have the following:
y = x/5 + 0.4 or (x + 2)/5

According to the best calculations of scientists, the universe is 13.8 billion years old. However, we are not totally certain of its age, as we are with so many of the largest-scale characteristics of the cosmos. The cosmos may be as young as 11.4 billion years old, according to two opposing estimations based on two competing measures of its rate of expansion.
Finding the oldest star and working backwards from there using what we know about how stars are generated would be the simplest method to determine the age of the universe.

Solve x ≥ 0 or x ≥ -5 and write the solution in interval notation.
In the interval notation, the answer is [-5, ∞), for both x 0 and x -5.
When representing numbers between two numbers, either excluding or including the numbers, depending on the need, interval notations are employed. We employ the four interval notations shown below:
All digits from [a, b] up to and including both a and b.
All numbers between a and b, but not including an or b.
All numbers in the range (a, b), omitting a but including b.
[a, b] All numbers in the range [a, b], inclusive of a but exclusive of b.
The answer for x 0 and x -5 must be expressed using interval notation.
Each inequality is initially expressed in interval notation:
All numbers larger than 0—including 0—have the value x. This can be expressed as [0, ∞) in interval notation. Because is ambiguous, we omit it.
All numbers greater than -5, including -5, are expressed as x -5 x. This can be represented as [-5, ] in interval notation. Because is ambiguous, we omit it.
Now, we must find a solution for x 0 or x -5. Since the answer is "or," we take the unions of the two sets, hence the answer is:
[0, ∞) ∪ [-5, ∞) = [5, ∞).
The answer in interval notation for x 0 and x -5 is therefore [-5, ∞).
