Correct Answer
A. Penghasilan dan umurExplanation
The variables "penghasilan" (income) and "umur" (age) are both quantitative variables because they can be measured and expressed numerically. They represent numerical values that can be compared and analyzed. On the other hand, "jenis kelamin" (gender), "tingkat pendidikan" (education level), "jumlah keluarga" (number of family members), "status perkawinan" (marital status), and "pendidikan" (education) are categorical variables because they represent categories or groups that cannot be measured numerically.Rate this question:

Correct Answer
B. Deret berkalaExplanation
The given correct answer, "Deret berkala," is the most appropriate explanation for the series of data described in the question. It states that the data consists of a series of observations where the variable Yi is a function of the variable Xi, which represents time moving uniformly and in the same direction from past to future. This suggests that the data follows a periodic pattern or a cyclical trend, which is characteristic of a "deret berkala" or a periodic series.Rate this question:

Correct Answer
A. ResesiExplanation
The question asks for the component that is not included in a periodic series. Resesi is the correct answer because it refers to a period of economic decline and is not a component of a periodic series. On the other hand, tren sekuler (secular trend), variasi sikli (cycle variation), variasi random (random variation), and variasi musim (seasonal variation) are all components that can be present in a periodic series.Rate this question:

C. Trend sekulerExplanation
The correct answer is "Trend sekuler". A secular trend refers to a long-term pattern or direction of development that shows a general upward or downward movement. It is a sustained trend that lasts for an extended period, usually spanning several years or decades. This term is commonly used in economics and finance to describe long-term trends in economic indicators, such as GDP growth or stock market performance.Rate this question:

Correct Answer
B. SikliExplanation
The question is asking for a movement or pattern that can repeat after a certain period of time, but may also not repeat within the same time frame. The term "sikli" in Indonesian means "cycle" or "cyclic", which fits the description given in the question. Therefore, "sikli" is the correct answer.Rate this question:

Correct Answer
C. IncreasingExplanation
The correct answer is "Increasing". The question is asking for an exception to the complete cycle of movements, and "Increasing" does not fit into the pattern of a typical cyclical movement. It is not a phase or stage in a cycle, but rather a continuous upward trend or growth. The other options, such as "Recovery," "Prosperity," "Recession," and "Depression," are all phases that are commonly seen in a complete cyclical movement.Rate this question:

The given correct answer for this question is "Musiman". This is because the sentence mentions the habits of giving gifts during New Year, Eid al-Fitr, and Christmas, as well as consumption before New Year and other big days. These events occur at specific times of the year and are repeated annually, indicating a seasonal pattern. Therefore, the correct answer is "Musiman" which means seasonal in English.Rate this question:

Correct Answer
C. Nilai tren pada tahun dasarExplanation
The correct answer is "Nilai tren pada tahun dasar". In the given linear trend line equation Y = a + bx, the term "a" represents the value of the trend at the base year. This means that when the time variable (x) is equal to zero, the value of Y will be equal to "a", which represents the trend value at the base year.Rate this question:

- C.
1,2,1
- D.
1,2,2
- E.
2,1,1
Correct Answer
C. 1,2,1Explanation
The correct answer is 1,2,1. This is because a binomial coefficient is used to calculate the coefficients in a binomial expansion. In this case, the binomial coefficients represent the weights or proportions assigned to each year in the moving average calculation. The first and last year are given a coefficient of 1, indicating that they have equal importance in the calculation. The middle year is given a coefficient of 2, indicating that it has double the weight of the other years. This suggests that the middle year is considered more significant or influential in the calculation of the moving average.Rate this question:

Correct Answer
C. Gempa bumi, dan pemogokanExplanation
Random variations are generally caused by unpredictable events such as earthquakes and strikes. These events can disrupt normal patterns and introduce unexpected changes in various aspects of life. Gempa bumi (earthquakes) are natural disasters that can have widespread effects on infrastructure, transportation, and daily activities. Pemogokan (strikes) can occur in various industries and sectors, leading to disruptions in production, services, and supply chains. Both earthquakes and strikes can introduce random variations that are beyond the control of individuals or communities, affecting the overall stability and predictability of a system.Rate this question:

Diketahui jumlah dari perkalian harga sekarang dan barang awal adalah 52,5. Sedangkan jumlah dari perkalian harga awal dan barang awal adalah 44,75. Hitunglah indeks harga Laspeyres!
- A.
117,3%
- B.
95%
- C.
100%
- D.
80%
- E.
85,2%
Correct Answer
A. 117,3%Explanation
The Laspeyres price index is calculated by dividing the sum of the current prices multiplied by the base quantities by the sum of the base prices multiplied by the base quantities. In this case, the sum of the current prices multiplied by the base quantities is 52.5, and the sum of the base prices multiplied by the base quantities is 44.75. Dividing these two values gives us a Laspeyres price index of 117.3%.Rate this question:
