Answer:
b
Step-by-step explanation:
Surface of the earth =3959×3.14
=12,437.565
if 20%is suitable so we multiply it by the surface
12,437.565×0.2=2,487.513 per people
2,487.513/7,700,00,00
So I think it will be the closest to b
Answer:
Value of the test statistic, 
Step-by-step explanation:
Null hypothesis, 
Alternative hypothesis, 
Sample mean, 
Sample size, n = 110
Standard deviation, 
Significance level, 
The value of the test statistics is given by the formula:
The z-score tells you how many standard deviations from the mean.
<span>1.5 * 3.6 = 5.4 miles </span>
<span>So anything within 5.4 miles of the average (29). </span>
<span>The range would be: </span>
<span>29 - 5.4 = 23.6 </span>
<span>to: </span>
<span>29 + 5.4 = 34.4 </span>
<span>23.6 ≤ x ≤ 34.4 </span>
<span>Answer: </span>
<span>B) 24 miles</span>
Answer:
The correct answer is option B. Return on Investment.
Step-by-step explanation:
The return on investment is used when we want to measure the capacity of an investment, or compare it among several other investments.

ROI = Margin on sales X asset turnover.
Now let's clarify what each of these things is:
Margin on sales: it is the result obtained from the calculation of benefits / sales.
Asset Rotation: this is the result obtained from the calculation of Average Total Sales / Assets.
