Keep in mind x >0 since x is a measurement of length.
1+3+5+7+9+11+13+15+17+19 is the answer. Hopefully this helped!! :)
Answer:
I don't understand the arrangement of the "table." I'll assume the question wants to know the values of b as a increase from 2 to 6.
Step-by-step explanation:
The resulting table is attached.
There are 25 species of trees, each with a known abundances. The question is how many possible ways to randomly select one tree there are.
We should calculate the number of combinations. Combinations, because we select item/s from a collection. In this case, when we select only one item, the combination is also a permutation. From set of n objects we select r. In our case: n=25, r=1.
The equation is: n!/r!(n-r)!= 25!/1!*24!=25*24!/24!=25
There are 25 different outcomes (events).
