Answer:

The galaxy is moving closer to us

Explanation:

When there is a decrease in the wavelength of light which is being observed then it means that the object and observer are getting closer to each other.

When there is an increase in the wavelength of light which is being observed then it means that the object and observer are getting farther apart.

This phenomenon is called the Doppler effect.

Orange has shorter wavelength than red so the wavelength is getting shorter.

Hence, the galaxy is moving closer to us.

Suppose an economist says that "other things equal, the lower the price of bananas, the greater the amount of bananas purchased.
V125BC [204]

Answer:

C) All factors other than the price of bananas (for example, consumer tastes and incomes) are assumed to be constant

Explanation:

When developing an economic model, only a limited number of variables can be taken into account for the sake of simplicity and understanding. Economic models never give a full picture of reality, only an approach.

The economic model alluded in the question is perhaps the most famous of all: the supply and demand model. It tells us that, assuming all else constant, the higher price, the less quantity is demanded, and the lower the price, the more quantity is demanded.

Click to read the "Correlation vs. Causation" article. In your own words, explain the problem of correlation vs. causation. Why
Katyanochek1 [597]

Answer:

Correlation and causation are two very different things

Explanation:

Correlation means that two or more factors are dependent on each other in a way that one can be predicted with the help of the other. On the other hand, causation means that one thing causes another. For instance, a correlation between ice cream consumption and hot weather means that when its hot people eat ice cream more and in less hot weather people eat less ice cream. But if this correlation is confused with causation between ice cream demand and hot weather then it would mean that eating ice cream causes hot weather which will not be correct. Also for causation, three criteria should be met which are correlation, no effect of third extraneous variable and this casual effect should precede all other rational effects.
