I guess the correct answer is the color of the decorations in the room
A group of researchers wanted to determine if people will eat more food in a room with red paint and red decorations than in a room that is decorated blue. Half the participants in this study ate in a red room and half ate in a blue room. The researchers then measured how much food was consumed in each of the two rooms. In this study, the independent variable was  the color of the decorations in the room.

Answer:
$412,500
Explanation:
March 
Cash receipts from sales on account for April = $400,000 * 75%
Cash receipts = $300,000
April
Cash receipts from sales on account for April = $450,000 * 25%
Cash receipts = $112,500
Total Cash receipts = Cash receipts from sales on account from March + Cash receipts from sales on account from April
Total Cash receipts = $300,000 + $112,500
Total Cash receipts = $412,500
 
        
             
        
        
        
Answer:
Human needs are the impulse that individuals have to access certain goods or things. Scarcity, in turn, is the lack of goods or things to meet the needs of all humans in general.
Therefore, all human needs could be covered without major problems if the phenomenon of scarcity did not exist, that is, if there were more goods available than those demanded by society.
 
        
             
        
        
        
Answer:
1) Flitcom Corp (Beta = 0.60)
2) Tobotics Inc. (s.d. = 11%)
Explanation:
1. Suppose all stocks in Ariel's portfolio were equally weighted. Which of these stocks would contribute the least market risk to the portfolio?
The indicator of the market risk is the Beta. It relates the variation of the price or value of the stock relative to the variation of the total stocks in the market.
The value of Beta indicates how risky is a stock relative to the risk of the market. A Beta =1 means it has the same systemic risk as the market. If Beta<1, the stock is less volatile than the market, and if Beta>1, it is more volatile than the market.
Then, the stock with less value of Beta will contribute the least risk to the portfolio.
This is the case of Flitcom Corp (Beta=0.60)
2. Suppose all stocks in the portfolio were equally weighted. Which of these stocks would have the least amount of stand-alone risk?
The stand-alone is reflected by the standard deviation. The less the standard deviation, the less risk of the stock (measured only the stock variability).
This is the case of Tobotics Inc. (s.d. = 11%)
