Answer:
1. Necro- c. Death.
2. Therm- a. Heat.
3. Arachn- e. Spider.
4. Claustr- d. Small space.
5. Soph- b. Wisdom.
Explanation:
1. "Necro" means anything related to death or dying or even dead bodies or corpses. The fear of death of anything death-related is known as necrophobia.
2. The word "therm" is usually related to the term "heat". It is also the unit of heat which makes the fear of heat to be thermophobia.
3. "Arach" is a term relating to the spider family. Thus, the fear of spiders is arachnophobia.
4. "Claust" refers to any small, congested space. Claustrophobia is the fear or small space or an enclosed congested space.
5. Soph is a word related to wisdom or knowledge. Thus, sophobia means to have a huge fear of learning of knowledge or wisdom.
False, Time Series methods base forecasts only on past variables and not on recent values.
Forecasting in time series is done when we make scientific predictions based on historical data. Time series involves building models through the analysis of historical data and using them to make observations that help in decision-making. The methods of time series refer to the different ways to measure the timed values.
There are four different components of the methods of time series. The first one is a secular trend which helps to describe the movement along the term. The second one is seasonal variations that help to show seasonal changes. The third one is cyclical fluctuations that correspond to periodical changes. the last component is irregular variations that happen at random.

Answer:
170 L
Explanation:
Boyles laws states that the pressure exerted by a gas is directly proportional to the volume it occupies provided that the temperature is held constant. Boyles law is given by:
PV = constant
P₁V₁ = P₂V₂
Given that the initial volume V₁ = 200 L, initial pressure P₁ = 850 atm, final volume V₂ = 1000 atm and final pressure = P₂.
Applying Boyles law gives:
P₁V₁ = P₂V₂
850(200) = 1000(V₂)
V₂ = 170 L
