From the given Image :

Mean = Sum of all the observations/ Number of observations = (87+46+90+78+89)/5 = 78
Variance = SD^2 ------ SD = Standard deviation
It means that with Variance, square root is never taken.
Therefore,
Variance = Summation of square of differences between observation and the mean divided by the number of observations.
That is,
Variance = {(87-78)^2 + (46-78)^2 + (90-78)^2 + (78-78)^2 + (89-78)^2}/5 = 274
Answer:
Biosphere 2 is a unique facility that allows scientists to research ecosystems and environmental effects in a controlled environment. The controlled environment of the biosphere allows researches to obviate uncontrolled variables that might have an unintended effect on their research. This allows for specific hypothesis about the environment to be tested with a higher degree of certainty. They can study how the ecosystem is affected when there are artifically induced limiting factors. The ability of the scientists to control factors in the ecosystem lets them model almost any environment on earth.
Answer: 2^2 x 3^2 x 5
You can use a star symbol * in place of the x symbols.
==================================================
Explanation:
We simply circle the primes where they have the largest exponent.
The unique primes listed here are: 2, 3, 5
- The prime 2 has the highest exponent of 2, meaning 2^2 is part of the answer.
- The prime 3 has the highest exponent of 2, meaning 3^2 is also part of the LCM
- The prime 5, without any exponent, is also part of the LCM. We can write this as 5^1 or just leave it as 5.
