Answer:
The soil of the region A (given in the attachment) must have coarse grain sand and gravel deposits.
Explanation:
The remaining part of the question is attached here
Solution
Most of the aquifers are recharged by rainfall or either the surface water that penetrates through the soil into the ground and reaches the aquifer. Hence, the soil type in these regions must be permeable. Gravel and coarse sand along with medium seize sand particles have high permeability. Hence, the soil of the region A (given in the attachment) must have coarse grain sand and gravel deposits.
Not true, you should change your rule to include the exception
Answer: Look at the explanation.
Explanation: An environmental consequence could be our land. The more land we use for agriculture results in loss of biodiversity. Slash-and-burn kills many trees and plant life. These trees are home to many small animals and now they are homeless and will die unless they adapt and find a new land. A social consequence could be food deserts. Food deserts are caused by and increase poverty and starvation. Nonexistent stores in rural areas do not help the population. People starve and barely have another way of getting healthy food. They rely on fast food chains which do not help with health.
Answer:
Number of students ; 60
Explanation:
Using the formula for p +- z * Sqrt ( pq/n )
Let us first calculate the Margin of Error
= 0.816 –0.7 = 0.116
•z* = 1.96
P = (0.584 + 0.116 ) = 0.7
Q = 1- p = 1 – 0.7 = 0.3
Now inserting the values in the formula; we get
0.116 = 1.96 x sqrt { ( 0.7 x 0.3) / n }
Solving the above equation
N = 60 (rounded off to nearest number)
Hence the number of students that were selected by the environmental teacher in the sample is 60
