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:
20%
Explanation:
Return on assets is a profitability ratio that shows how much in net income a company is able to generate from its assets.
It is a financial measure that shows the net profit a company is able to generate per $1 invested in assets.
Mathematically,
Return on asset = net income/average total asset
= $800,000/$4,000,000
= 0.2
= 20%
This means that the company's management is a to generate a net income of 20 cents for every $1 invested in assets.
Answer:
Standard deviation = 47.69% (Approx)
Explanation:
Given:
Portfolio of Apple stock w1 = 25% = 0.25
Portfolio of Tesla stock w2 = 75% = 0.75
Standard deviation return Apple σ1 = 35% = 0.35
Standard deviation return Tesla σ2 = 60% = 0.60
Correlation coefficient ρ12 = 0.22
Find:
Standard deviation
Computation:
Standard deviation = √w1²σ1² + w2²σ2² + 2w1σ1w2σ2ρ12
Standard deviation = 0.4769
Standard deviation = 47.69% (Approx)
Answer:
It will take 30 years for country Y’s GDP to catch up with that of country X
Explanation:
In this question. We are asked to calculate the number of years it will take a certain country Y to catch up with the GDP of a certain country X, given the annual growth rate in both countries.
We calculate the number of years as follows;
Firstly, we assign a variable to the value of the real GDP of country Y
let real
Let the real GDP of the country Y be n. This means that the GDP of country C will be 4 * n = 4n
With a 7% growth rate annual, country Y's Real GDP will be doubled in 70/7 = 10 years and;
With annual growth rate of 2.33% ,country x's Real GDP doubles in 70/2.33 = 30 years.(Approx)
Now in next 30 years x's Real GDP will be = 2x4n = 8n
and Y's Real GDP in next 30 years will be = 2x2x2xn = 8n.
thus , it will take 30 years to country Y to catch up to the level of country x.
Hi There!
Complainer in the workplace?
There are days where employees seem to be complaining about everything. In many companies, misery loves company, and it's a big problem for small-business owners. It can bring down employee morale, and affect employee productivity and retention. Ultimately, it will trickle down to the customers—resulting in sub-par service and a decrease in sales.
Negativity is rampant in the workplace. According to Jim Harter, Gallup’s chief scientist for workplace management, 18 percent of U.S. employees are “actively disengaged,” and will complain about their companies.
