To determine the number of deer in a game preserve, a forest ranger catches 630 deer, tags them, and releases them. Later 179 deer are caught, and it is found that 42 of them are tagged. Assuming that the proportion of tagged deer in the second sample was the same as the proportion of tagged deer in the total population, estimate the number of deer in the game preserve. The number of deer in the game preserve is:.

The base of a triangle exceeds the height by 7 centimeters. if the area is 400 square centimeters, find the length of the base and the height of the triangle.

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

Assume that there is a 11% rate of disk drive failure in a year. a. if all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. if copies of all your computer data are stored on four independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
