What is the sample variance of the following data, which describe the height growth of 10 foxtail pine trees grown in a common garden ( give your answer to one decimal place)?
Tree Height(cm)
1 25.6987
2 19.6587
3 11.4780
4 9.11130
5 16.8747
6 14.7771
7 33.0001
8 24.0000
9 19.4441
10 14.1010
answer 51.9
Explanation:
what is a sample variance?
A sample variance (denoted as 
) is used to calculate how far a set of numbers are from the mean value of the set. Mathematically, it is defined as the average of the squared deviations from its mean value.
Let the individual value of the trees be represented as x₁ to x₁₀
Let the total number of Foxtail pine trees be N
To calculate the standard deviation, we will first calculate the mean or average of the height of the trees
1. Mean (μ) = 
= 
= 
2. we need to calculate the sum of the squares of the individual deviations.
∑[x-μ]²= 
3. Now the variance is ; (∑[x-μ]²) ÷ (N-1) and since N=10, then N-1 = 10-1 = 9
= 
we were asked the give our answer to one decimal place
∴ Variance()= 51.9
Answer:
Probably because a drought does not mean that water disappears.
Turning off the faucet doesn't mean that water can't go down the drain, right?

The second row of values in plant experiment most likely to have "high oxygen level and carbon dioxide level would be the same".
Explanation:
The procedure by which living things convert oxygen and glucose to water and carbon, accordingly yielding vitality is called photosynthesis. It does not require the nearness of daylight and is continually happening in living life forms. Cell breath occurs in the mitochondria of cells.
Through these procedures, plants get the carbon dioxide they need, and living life forms get the oxygen they need. They are additionally crucial to the vitality trade that living things need to endure.
C. They both have cell membrane
