Answers

Answer 1

Answer:

36.

Step-by-step explanation:

There were 10 elephants that were marked. Only 4 of those were counted. The other 26 were new elephants. Because of this, we know that there were 6 other elephants that were not counted. There were the 30 counted, and the other 6. Add those and you get 36.

Answer 2

Answer:

75 elephants

Step-by-step explanation:

This sort of population study assumes that the probability of catching any particular elephant is the same as for any other.

We are given that there is a population of 10 painted elephants, of which 4 of them are caught in a sample of 30 elephants. We know the total population of painted elephants is 10/4 = 2.5 times the number caught in the sample. This suggests the total population of elephants is 2.5 times the sample size.

estimated population = 2.5 × 30 = 75 . . . elephants

Aside from her school and other crumbling buildings in their neighborhood, their world was a few rooms in a dull, gray concrete flat with no yard and no trees. The wall was part of the view from the only windows they had, and Inge was drawn to the sounds she often heard from the other sidelaughter, shouting, music, and the noise of busy traffic.One day, as she explored the wall imagining what the sounds meant, she came upon a hole. Her heart thumped wildly as she leaned toward it. Through the hole, Inge caught a glimpse of a whole new world. It was a world of colorreds, blues, and yellows in the dresses of women strolling down the street, the colors of the shirts and ties the men wore, the colors of the ribbons in the little girls' braids. It was a world of people who did not begin and end each day in shades of gray. It was alive and brimming with activity, with living. Inge leaned, transfixed by the view, for hours until she began to feel the strain in her back and leg muscles. Then, pulling herself away, she headed home, knowing she would return again and again.One fall day in 1990, as Inge headed for her favorite spot in the wall, she noticed that the towers from which the guards viewed her neighborhood were empty. And she noticed something else: she was not alone. Others, mostly young men with a mix of other people, some of whom she recognized were at already at the wall or moving toward it.
