Seasonality is a data pattern that repeats itself after a period of weeks, days, months, or quarters.
The progressive upward or downward movement of the data over time is referred to as a trend. Trend movement may be explained by shifts in income, population, age distribution, or cultural perspectives.
Data patterns called cycles appear every few years. They play a significant role in short-term company analysis and planning and are typically linked to the business cycle. Because they might be influenced by worldwide unrest or political events, business cycles are challenging to predict.
Data "blips" are caused by chance and uncommon circumstances and are known as random fluctuations. They exhibit no clear pattern, making prediction impossible.
Seasonality is a recurring trend in data that occurs every few days, weeks, months, or quarters. Six typical seasonality patterns exist.
Hence, the correct option is (d) seasonality.

What are Interior Angles?Interior angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles
The method that can not be used to prove that lines i and k are parallel is the statement "shows that both lines are perpendicular to a third line".
Lines l and k intersect forming two pairs of vertical angles. If one of these angles measures 120°,
As per the given question,
Let angle ∠1 is 120°
here angles ∠1 and ∠2 are supplementary
So ∠2 = 180° - 120° = 60°
However, if a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.
∠2 = ∠4 = 60°
∠1 = ∠3 = 120°
Therefore, the measures of the other three angles are 60°, 60°, and 120°.

This is an explain your reasoning question. You will need to show all your work and explain how you arrived at your answer.
Answer:
m∠R = 72°
Step-by-step explanation:
As ΔPQR and ΔUVW are congruent, m∠R = m∠W.
Equate the expressions for the two angles and solve for x:
⇒ m∠R = m∠W
⇒ 10x - 18 = 8x
⇒ 10x - 18 + 18 = 8x + 18
⇒ 10x = 8x + 18
⇒ 10x - 8x = 8x + 18 - 8x
⇒ 2x = 18
⇒ 2x ÷ 2 = 18 ÷ 2
⇒ x = 9
Substitute the found value of x into the expression for m∠R:
⇒ m∠R = 10x - 18
⇒ m∠R = 10(9) - 18
⇒ m∠R = 90 - 18
⇒ m∠R = 72°
Therefore, m∠R = 72°.

The cost of each land is 120,000 dollars.
How to find the cost of each land?The mountain cabin on 1 acre of land costs 30,000 dollars.
The land cost 4 times as much as the cabin.
Therefore, the cost of each land can be calculated as follows:
cost of each land = 4 (30, 000)
cost of each land = 4 × 30000
cost of each land = 120,000 dollars
Therefore, the land that cost 4 times as much as the cabin cost 120000 dollars for each.

What are angles?In Euclidean geometry, an angle is a shape created by two rays that share an endpoint and are referred to as the angle's sides and vertex, respectively. The plane that contains the rays contains the angles created by two rays. The meeting of two planes can also result in an angle. They are referred to as dihedral angles.So, first label the lines as A, B, C, and D as follows:
Refer to the image attached below.
As we can see that line ADB is a straight line, so ∠ADB will be 180°.Line DC cuts the angle ∠ADB in two parts, so the equation can be:
(6x + 5) + 67 = 180Now, solve for x as follows:
(6x + 5) + 67 = 1806x + 72 = 1806x = 180 - 726x = 108x = 108/6x = 18°Therefore, in the given angle, the value of x is 18°.

Answer:
x + 2y = 5
Step-by-step explanation:
y = mx + b the m is the slope or gradient.
y=2x+3 The slope is 2.
When lines are perpendicular, the slopes are opposite inverses of each other. So, the perpendicular slope to 2 is -1/2. I would write the answer in the point slope of the line and then change the equation to the stand form
y -2 = -1/2(x -1) Distribute the -1/2
y - 2 = -1/2x + 1/2 Add 1/2 x to both sides
1/2x + y -2 = 1/2 Add 2 to both sides
1/2x +y = 5/2 Multiply by 2 to clear the decimal
x + 2y = 5
if 9^(2-x)=3,find the value of x
9^(2-x) = 3 -> 2-x = 1/2
into details about why it is 1/2 (ill call 2-x as y for easier demonstration)
9^y = 3
(3^2)^y = 3
And we have : (x^m)^n = x^mn
-> (3^2)^y = 3^2y = 3
-> 2y = 1
y = 1/2, therefore 2-x = 1/2.
So, x = 2 - 1/2 = 3/2.

The equation to represent the cost of each drink is 3(x + 2.5) + 3x = 25.50. The cost of each drink will be $3.
In the given question, it is stated that the family spent a total of $25.50 and they bought 3 Popcorn and 3 Drinks. Each popcorn costs $2.5 more than the drink. Now, suppose the cost of one drink is 'x' then we get:
Cost of 3 Drinks = 3x
Cost of 3 Popcorn = 3(x + 2.5)
The equation to represent this will be:
=> 3(x + 2.5) + 3x = 25.50
=> 3x + 7.5 + 3x = 25.50
=> 6x = 18
=> x = 3
We get x = 3, Cost of one drink will be $3
Hence, equation representing it will be 3(x + 2.5) + 3x = 25.50, and the cost of each drink will be $3

The x-intercepts of the function are 10, and -8.
y-intercept is: -80.
The zeros are: x = 10 and x = -8
f(2) = -80
f(x) = -65 when x = 5 or -3.
What is the Y-intercept and the X-intercept of a Function?The y-intercept of a function is the output (y) when the input value (x) is zero. On the other hand, the x-intercept is the input value (x), when the output value (y) is zero.
What are the Zeros of a Function?The zeros of a function are the x-intercepts of a function.
Given the function, f(x) = x² - 2x - 80, substitute f(x) = 0 to find the value of x, which is the x-intercept:
0 = x² - 2x - 80
x² - 2x - 80 = 0
Factorize
(x - 10)(x + 8)
x = 10 or x = -8
Substitute x = 0 into the function to find the y-intercept:
f(0) = 0² - 2(0) - 80
f(0) = -80
x-intercepts are 10, and -8.
y-intercept is: -80.
The zeros are: x = 10 and x = -8
Find f(2):
f(2) = (2²) - 2(2) - 80,
f(2) = 4 - 4 - 80
f(2) = -80
Find x when f(x) = -65:
-65 = x² - 2x - 80
-65 + 80 = x² - 2x
15 = x² - 2x
x² - 2x - 15 = 0
Factorize
(x - 5)(x + 3) = 0
x = 5; x = -3
Therefore, f(x) = -65 when x = 5 or -3.

The strategy used by Dr. Chang for the research study of undergraduate students is c. stratified sampling.
Stratified sampling can be defined as the type of sampling in which a population is divided into subpopulations and then random samples are taken from these subpopulations. These subpopulations or subgroups are also called strata.
The strategy used by Dr. Chang is stratified sampling because she divided all the undergraduate students into subgroups based on grade level and then from these subgroups she randomly selected 50 students.
Contrastingly, in simple random sampling, no subgroups are involved and the subset of individuals are chosen from a single large population randomly. On the other hand, quota sampling and accidental sampling are not a type of random sampling.
In cluster sampling, the subgroups are internally heterogeneous but in this case, the subgroups are internally homogenous as they are made based on grade level.
