The translation of the question is:
<h3>What are solar parks?</h3>
The solar park is a concentrated zone of development of solar power generation projects and provides developers an area that is well characterized, with proper infrastructure and access to amenities and where the risk of the projects can be minimized.
How many solar parks are there in China?
- Huanghe Hydropower Hainan Solar Park – 2.2GW
- Tengger Desert Solar Park – 1.55GW
- Datong Solar Power Top Runner Base – 1.1GW
- Yanchi Ningxia Solar Park – 1GW
- Longyangxia Dam Solar Park – 850MW

#SPJ1
Because, often times, water pollutants occur in small amounts. Therefore, it is likely to use small percentages (less than 1%) in comparison to the water and various other pollutants in the same sample.
Answer:
a. [ 0.454,0.51]
b. 599.472 ~ 600
Step-by-step explanation:
a)
Confidence Interval For Proportion
CI = p ± Z a/2 Sqrt(p*(1-p)/n)))
x = Mean
n = Sample Size
a = 1 - (Confidence Level/100)
Za/2 = Z-table value
CI = Confidence Interval
Mean(x)=410
Sample Size(n)=850
Sample proportion = x/n =0.482
Confidence Interval = [ 0.482 ±Z a/2 ( Sqrt ( 0.482*0.518) /850)]
= [ 0.482 - 1.645* Sqrt(0) , 0.482 + 1.65* Sqrt(0) ]
= [ 0.454,0.51]
b)
Compute Sample Size ( n ) = n=(Z/E)^2*p*(1-p)
Z a/2 at 0.05 is = 1.96
Samle Proportion = 0.482
ME = 0.04
n = ( 1.96 / 0.04 )^2 * 0.482*0.518
= 599.472 ~ 600
Answer:
9 =x
Step-by-step explanation:
The angles are vertical angles and vertical angles are equal
56 = 6x+2
Subtract 2 from each side
56-2 = 6x+2-2
54 = 6x
Divide each side by 6
54/6 = 6x/6
9 =x
1 liter = 1.05669 quarts
3 liters = 3.17006 quarts
