Answer: D) Groundwater collects only where the soil and geological features allow water to seep down into underground chambers.
In other words, as long as there are gaps to allow water through, then that would lead to underground aquifers. Another important component is the amount of rain water that happens. Sources such as rivers, lakes and streams are also a contributing factor.
Stuff like earthquakes, volcanic activity, and continental movement doesn't really have much an effect on where or how aquifers form. It's really all about the soil type and how the landscape is formed, and of course the other factors mentioned in the previous paragraph.
Answer:
Step-by-step explanation:
From the information given,
Mean, μ = (10.31 + 17.22 + 26.62 + 22.84)/4 = 19.2475
Standard deviation, σ = √summation(x - mean)/n
Summation(x - mean) = (10.31 - 19.2475)^2+ (17.22 - 19.2475)^2 + (26.62 - 19.2475)^2 + (22.84 - 19.2475)^2 = 151.249475
σ = √(151.249475/4)
σ = 6.15
number of sample, n = 4
The z score for 98% confidence interval is 2.33
We will apply the formula
Confidence interval
= mean ± z ×standard deviation/√n
It becomes
19.2475 ± 2.33 × 6.15/√4
= 19.2475 ± 2.33 × 3.075
= 19.2475 ± 7.16
The lower end of the confidence interval is 19.2475 - 7.16 = 12.09
The upper end of the confidence interval is 19.2475 + 7.16 = 26.41
L -2= (1/5)w
P = 2l +2w
P = 2((w/5)+2) +2w
P = 2((10+w)/5 +2w
Hello!
Since we are given the zeros for each function, we can write the equation in factored form first, and then we can simplify it into standard form. Remember that if you were to use the zero product property to find the zeros of a quadratic function, you would need to subtract or add the factors to find the zeros.
1. x = -2 and x = -5
(x + 2)(x + 5) = 0
x² + 7x + 10 = 0
2. x = -2 and x = 0
x(x + 2)
x² + 2x = 0
3. x = -2
(x + 2)² = 0
x² + 4x + 4 = 0
Therefore, the answer to question one is x² + 7x + 10 = 0, the answer to question two is x² + 2x = 0, and the answer to question 3 is x² + 4x + 4 = 0.
