Answer:
x = 7
Step-by-step explanation:
Let's solve the problem,
→ 4x - 2x + x - 6 = 15
→ 3x - 6 = 15
→ 3x = 15 + 6
→ x = 21/3
→ [ x = 7 ]
Thus, the value of x is 7.

The mean absolute deviation of this data set is 0.2
What is the mean absolute deviation of this data set?The dataset is given as
0.7, 1.4, 3 and 2
Calculate the mean using
m(x) = Sum/Count
So, we have
m(x) = (0.7 + 1.4 + 3 + 2)/4
Evaluate
m(x) = 1.775
The mean absolute deviation is calculated as
Deviation = 1/n∑|(x - m(x))|
So, we have
Deviation = 1/4 * (|0.7 - 1.775| + |1.4 - 1.775| + |3 - 1.775| + |2 - 1.775|)
This gives
Deviation = 1/4 * (-1.075 + 0.375 + 1.225 + 0.225)
Evaluate
Deviation = 0.1875
Approximate
Deviation = 0.2
Hence, the mean absolute deviation of this data set is 0.2

What is function?
A function is a type of rule that produces one output for a single input. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is the input value, we would state that y is a function of x.Four main categories can be used to classify different sorts of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element.f(x) = 5x + 6

Solve using PEMDAS
11²-[3. (8-5)*7-19=
Step-by-step explanation:
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)
Answer:
39.
Step-by-step explanation:
I say good try to the first guy, but aye, it's not fully answering the question.
PEMDAS is the order you solve all of this in. Parenthesis (), Exponents (^), Multiplication (*), Division (/), Addition (+), and Subtraction (-).
We would solve (8-5) first for 3, since there is no sign between both three's, this will be multiplication.
Next is the exponent, 11^2 is 11*11, which is equal to 121.
121 - 3 * 3 * 7 - 19
Next up is Multiplication. 3 * 3 = 9, and 9 * 7 is 63.
Now our equation is 121 - 63 - 19. There is no Division or addition symbol, so we skip to Subtraction.
121 - 63 = 58, and 58 - 19 = 39.
Your Answer is 39.

charlies mom just had a baby. he notices that they use an average of 9 dipers per day. At this rate, how many total dipers will they use during June and july this year?
We get that the total dipers that Charlie's mom will use in the month of June and July will be 549 dipers.
Charlie's mom uses an average of 9 diapers a day.
Average = 9
Average means a number that is calculated by adding quantities together and dividing the total by the number of quantities.
Average = Sum of observations / number of observations
A = S / N
We know that:
June has = 30 days
July has = 31 days.
Total days = 30 days + 31 days = 61 days
N = 61
Let the sum = S be x.
Substituting the values in the formula, we get that:
9 = S / 61
S = 9 × 61
S = 549
Therefore, we get that the total dipers that Charlie's mom will use in the month of June and July will be 549 dipers.

Change the following statement into coordinate points
a)f(-1)=1
b)f(2)=7
c)f(1)=1
d)f(3)=0
Changing [f(-1) = 1] into coordinate points, we get (x₁, y₁) = (-1, 1),
Changing [f(2) = 7] into coordinate points, we get (x₂, y₂) = (2, 7),
Also, changing [f(1) = 1] into coordinate points, we get (x₃, y₃) = (1, 1),
And finally, changing [f(3) = 0] into coordinate points,
We get (x₄, y₄) = (3, 0).
As per question statement, we are provided with Four separate functions, as follows, [f(-1) = 1], [f(2) = 7], [f(1) = 1] and [f(3) = 0].
We are required to convert the above mentioned functions into coordinate points.
To solve this question, we need to know the standard form of conversion of functions into coordinate points, which goes as [y = f(x)], i.e., the ordinate is a function of the abscissa.
Thus comparing [y = f(x)] to [1 = f(-1)], we get (x, y) = (-1, 1).
Similarly, comparing [y = f(x)] to [7 = f(2)], we get (x, y) = (2, 7),
Comparing [y = f(x)] to [1 = f(-1)], we get (x, y) = (-1, 1),
And finally, comparing [y = f(x)] to [0 = f(3)], we get (x, y) = (3, 0).

Find the length of AC if PQ is a segment bisector.
Show work.
Answer:
AC = 135 units
Step-by-step explanation:
since PQ bisects AB , then
BC = AC , that is
12x - 21 = 9x + 18 ( subtract 9x from both sides )
3x - 21 = 18 ( add 21 to both sides )
3x = 39 ( divide both sides by 3 )
x = 13
Then
AC = 9x + 18 = 9(13) + 18 = 117 + 18 = 135

Answer:
Algebraic Expressions- An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc. For example, let us have a look at the expression 2x + 4. Thus, we can say that 2x + 4 is an example of an algebraic expression.
Here are more examples:
• 5x + 4y + 10
• 2x2y - 3xy2
• (-a + 4b)2 + 6ab
To simplify an algebraic expression, we just combine the like terms. Hence, the like variables will be combined together. Now, out of the like variables, the same powers will be combined together
Multiply the numbers
x - 3 . 5x – 3x -12 - 4x + 18x - 7
= x – 15x - 3x – 12 – 4x + 18x – 7
Subtract the numbers
= x – 15x – 3x – 12 – 4x + 18x - 7
= x – 15x – 3x – 19 - 4x + 18x
Combining the like terms

The length and width of a rectangle are consecutive integers. The perimeter of the rectangle is 42 inches. Find the length and width of the rectangle.
Answer:
The length of the rectangle is 11 inches, and the width of the rectangle is 10 inches.
Step-by-step explanation:
Let l be the length of the longer side of the rectangle. Then the width of the rectangle is l-1 inches. Since the perimeter of the rectangle is 42 inches, we have:
2(l + l - 1) = 42
l + l - 1 = 21
2l = 22
l = 11 inches, so l - 1 = 10 inches

Definition of volumeAll matter occupies a space that can vary depending on its size. This space can be defined by volume, which is defined as the extension of an object in its three dimensions. That is, the volume corresponds to the measure of the space that a body occupies.
Volume of a cubeThe cube is a polyhedron or three-dimensional geometric figure, with six equal sides, each of which is a regular polygon, that is, a square. In other words, a cube is a body made up of six faces that are square.
The volume of a cube is equal to the measure of its side to the cube:
Volume = side x side x side = side³
Edge length of the fish tankIn this case, you know that:
The volume of the fish tank is 216 cubic inches.The fish tank is in shape of a cube.Replacing in the definition of volume of a cube:

Two cards are selected from a standard deck of 52 playing cards. the first card is not replaced before the second card is selected. find the probability of selecting and then selecting .
The probability of a given event gives a result of 0.00037. It is generated by applying the basic concepts of probability to the assigned problem.
What is probability?
Probability depicts the number of possibilities of how many times an event can occur. The probability of happening of an event invariably lies between 0 and 1. For a sure event, it is always 1. Its formula is given as P(E) = No. of favourable outcomes / Total no. of outcomes
Calculation of finding the probability according to the conditions specified
The entire number of cards in a standard deck = 52
Total number of favourable outcomes = 1
The probability of selecting two cards is given by P(E1) which is equal to 1 / 52
P(E1) = 1 / 52
Another card is selected without replacing the first card, so the total number of cards in the deck becomes 51. The probability of selecting a card from these 51 cards is given by P(E) i.e. (1 / 52) × (1 / 51)
P(E) = 1 / 2652
P(E) = 0.00037
