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.

What is the safest position in traffic?
MrRa [10]

With the fewest vehicles around you is the answer.

Simply put, the central seat is farthest from the impact of a collision and farthest from the airbag. The National Highway Traffic Safety Administration (NHTSA) recommends that all children under the age of 13 ride in the backseat, ideally in the center.

Assuming passengers fasten their children's seat belts, child seats, or booster cushions, the rear center seat is currently the safest seat in the car.

But as vehicle safety technology continues to improve, this ancient wisdom is beginning to change. According to the New York Times, in past model year cars, experts now recommend sitting in the front seats for adults over the age of 55 if they want the safest place.

Assume risk and return are positively related. which algebraic formula best represents this relationship
Mkey [24]
I believe the answer is: <span>Risk = m x Return where m is zero

When risk and return is positively correlated, aiming for higher return is only risk the loss of larger amount of capital.
<em>But the percentage loss to happen does not necessarily increased.
</em>Because of this, we can say that there is zero risk in putting more capital to get more profit.<em>
