What is Deviation?
The deviation is a metric used to determine the discrepancy between an observed variable's value and its predicted value. The deviation can be defined as the distance from the centre point.
Concept:
Each remote PIC who deviates from a Part 107 rule shall, upon request from the FAA administrator, submit a written report of such deviation.
Who is in charge of providing the participants with information on emergency procedures while utilising a small unmanned airplane in a commercial operation? The commander of the remote pilot.

There is no correct answer given.
Horizontal compression of f(x) = -x + 4 by a factor of 0.5 will be -2x + 4.
What is a horizontal function?A horizontal line that a function's graph looks to coincide with but does not really do so is said to be its horizontal asymptote. The final behavior of the function is determined using the horizontal asymptote.
Given, g(x) is a horizontal compression of function f(x) = - x + 4 by a factor of 0.5. Hence,
g(x) = -x / 0.5 + 4
g(x) = -2x + 4
Therefore, By a factor of 0.5, the horizontal compression of the function (f(x)) is -x + 4 will result in -2x + 4.

What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
X is the amount of the 20% saline solution
Y is the amount of the 40% saline solution
X + Y = 200
0.2X + 0.4Y = 0.20 * 200 = 40
Solving the first equation for Y and multiplying
the second equation by 10 to clear away the decimals
Y = 200 - X
2x + 4y = 400
2x + 4(200 - x) = 400

Which table of values represents the equation y = 7x - 3?
The table of values which represent the equation y = 7x - 3 is: table D.
What is an ordered pair?In Mathematics, an ordered pair can be defined as a pair of two (2) elements or points that are commonly written in a fixed order within parentheses as (x, y), which represents the x-coordinate or x-axis (abscissa) and the y-coordinate or y-axis (ordinate) on the coordinate plane of any graph.
In order to determine the true ordered pair that is a solution for the given linear equation, we would have to test the ordered pair contained in each table by substituting it into the linear equation as follows;
For ordered pair (-2, -1), we have:
y = 7x - 3
-1 = 7(-2) - 3
-1 = -14 - 3
-1 = -17 (False).
For ordered pair (-2, -19), we have:
y = 7x - 3
-19 = 7(-2) - 3
-19 = -14 - 3
-19 = -17 (False).
For ordered pair (-2, -15), we have:
y = 7x - 3
-15 = 7(-2) - 3
-15 = -14 - 3
-15 = -17 (False).
For ordered pair (-2, -17), we have:
y = 7x - 3
-17 = 7(-2) - 3
-17 = -14 - 3
-17 = -17 (True).
In this context, we can logically deduce that all of the coordinates in table D represents the equation y = 7x - 3.

The sum of any two sides of a triangle must be greater than the other thus 32 feet,21 feet, and 12 feet will be the correct so options (A),(B), and (D) are correct.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
As per the given,
To be a triangle of three side polygon the sum of any two sides must be greater than the third side.
If we take 32 feet,21 feet, and 8 feet.
21 + 8 = 29 < 32 so it will not form any triangle.
Thus, 8 cannot be taken. now let's take 32,21 and 12 here 21 + 12 = 33 > 32 so it will form a triangle this will be used for the project.

In angle JKL, if angle L is thirteen more than angle k and angle j is seven more than six times angle k, find the measure of each angle
The measure of Angle JKL mJ = 159.4°, mK = 3.8°, and mL = 16.8°.
What is the measure if Angle JKL?A ray is rotated about its endpoint, or vertex, to create an angle. The rotational difference between a ray's starting and ending positions is what is measured by an angle's degree.
If x = mJ, y = mK, and z = mL, then
Angle L exceeds Angle K by thirteen, hence z = y + 13 is the result (1)
Since angle J exceeds angle K by a factor of 7, x = 7(6y) = 42y (2)
X + Y + Z = 180 because the triangle's angles add up to 180°.
In place of (1) and (2) (3).
42y + y + (y + 13) = 180
44y + 13 = 180

Let BBB repreent the number of additional block that Joe reerve. 1) Which inequality decribe thi cenario?
Chooe 1 anwer:
The bare minimum required is $4500 to reserve 5 blocks totaling at least 34 rooms.
What is inequality?In mathematics, a relationship between two expressions or values that are not equal to each other is called "inequality".
Here,
The number of rooms Joe company needs is 50. Let the number of rooms needed be n, this can be represented by the inequality:
n ≥ 50
Joe has already reserved 16 rooms, therefore the number of additional rooms needed to be reserved = 50 - 16 = 34 rooms. At least 34 rooms have to be reserved, if B is the number of additional blocks that Joe reserves, the inequality is:
B ≥ 34
Each block contains 8 rooms therefore the minimum number of block (a) needed to be reserved = 34/8 = 4.25 = 5 to the next whole number. Therefore the minimum number of blocks needed is given as:
a ≥ 5
Since each block cost $900, let c represent the minimum amount of money needed, therefore the least amount of money needed is given as:
c = $900(5) = $4500
c ≥ $4500
The least amount of money needed is $4500 for booking 5 blocks that will reserve at least 34 rooms.

Part A: A highway's path can be found using the equation 2x − 3y = 21. Use the graphs of the functions to determine the number of intersections there will be between the railroad and the highway, and explain completely. (5 points)
Part B: A turnpike's route is determined by the equation y equals one third times x squared period Prove algebraically how many intersections there will be between the railroad and the turnpike, showing all necessary work. (5 points)
a) The number of intersections between the railroad and the highway is of: One.
b) The number of intersections between the railroad and the turnpike is of: Two.
How to define the linear function?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which the parameters are listed as follows:
m is the slope, representing by how much y changes when x is increased by one.b is the intercept, representing the value of y when x = 0.The points for the railroad are given as follows:
(-8, 0) and (0,5).
When x = 0, y = 5, hence the intercept is of:
b = 5.
When x increases by 8, y increases by 5, hence the slope is of:
m = 5/8.
Thus the equation for the railroad is of:
y = 5/8x + 5.
Then the number of intersections with the highway is of one, as they are linear functions with different slopes.
With the turnpike, the intersection is given as follows:
5/8x + 5 = x²/3
x² -1.875x - 15 = 0.
The discriminant is of:
(-1.875)² - 4(1)(-15) = 63.5.

Given
The cost of the gallon of milk earlier was $2.81
The cost of a gallon of milk now is $3.48.
The total time period is 10 years.
r = (F/P)ⁿ⁻¹ - 1
r = {(3.48/2.81)^(1/10) - 1}×100
r = {(1.238)^(1/10) - 1}×100
r = 0.0215 ×100
r = 2.15
Hence, when the cost of a gallon of milk increases from $2.81 to $3.48 over a period of 10 years the annual inflation rate is 2.15 percent.
