A new club opens with 20 members, plus an unknown number of members x from another club. The club allows only members to join
once a year. After the first year, the number of total members doubles.
The following year, half of the members that joined from the other club
leave, but another 40 people join. After the third year, the total number
of members triples. Give a non-simplified expression that represents the
total number of members at the club after the third year. Then simplify
your expression.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
