Biology question!?

63 In a life table for the population of a developing country, the first age interval is from 0–9 years of age. The second age interval is from 10–19 years of age. Whereas the mortality in the first interval is 8%, it is less than 1% in the second interval. This is different than what is expected in developed countries. What could be the reason for this difference?

a) Record-keeping in developing countries is inaccurate, resulting in an artificially high value for mortality rate.
b) Because humans in developing countries follow a type III survivorship curve, this is the expected result.
c) In developing countries the inadequacy of medical facilities, the presence of tropical diseases, and malnutrition contribute to a much higher infant mortality than that observed in developed countries.
d) Because the mortality at an earlier age is high, it is much lower in subsequent age intervals.

How do you solve this trig. problem?

A storm drain has a cross section in the shape of an isosceles trapezoid. The shorter base and each of the two equal sides measure 2 m, and x is the angle formed by the longer base of each of the equal sides. Write an expression for the area, A, of the cross section in terms of sin x and cos x.

Telescope help needed! ASAP! Have to order for holidays?

My husband wants a telescope. He has never had one before, but he figures things out quickly. Does anyone know of good package deals, maybe with a dvd to help him find things in the sky? I would like to spend around $250 give/take. I have read many pages and many say start out with bionoculars, but everyone tells me he will be disapointed if he wants a telescope. I also know enough to go somewhere other than Walmart/kmart etc. My head is spinning, so I need an easy way out. Will someone tell me a good tele. to start with. I would love for him to see something interesting like planets or other moons. Forgive me, this is not my strong point. Please give me some different models to look up. Thanks in advance!

im trying to prove that transitive property to my teacher that im right and the math book is wrong
Transitive property is if two quantities are equal to the same quantity, then they are equal to each other: if A=B and B=C then A=c.

doesn't this property work with parrle lines ?
