I need some help on this...

Suppose that y= (2 - log(100-x)) / 0.38 can be used to calculate the number of years "y" for "x" percent of a population of 936 sparrows to reach maturity. Approximate the percentage(to the nearest whole per cent) of sparrows that reached maturity after 1 year.

I'm just asking because every time I come to this catagory all the questions are below the calculas mark on math and are pretty easy at that.

Is it because no one is taking college level courses? or not even able to enter college?!

this would support the 75% of americans are below accademic intellegents level idea

CRACKS ON PROOFS OF EVOLUTION

At best the debate between creation and evolution will be a lively one replete with name calling on both sides. Supporters of evolution shout that it is no longer a theory but a fact. However, scientific arguments against it seems to be rising and with good reasons. Here are some reasons why.

1.DEFECTIVE DATING METHODS. Most of the dating methods used to argue that the earth is at least a billion years old are inaccurate to say the least. Meaning there is no real means to prove that the earth is just a few thousand years old, or it’s age runs into the billions of years.

2. EVIDENCE FROM OUR SOLAR SYSTEM that our solar system is quite young:
Research studies indicate that our sun is gradually shrinking at a steady rate of seconds of arc per century. At its rate of shrinkage, as little as 50,000 years ago the sun would have been so large that our oceans would boil. But in far less a time than 50,000 years, life here would have ceased to exist.
