Suppose that the 149 million square kilometers of land on the surface of the earth was divided equally among this population, so that each person was allotted a square parcel of land. How long would be the sides of each square parcel if the world has a population of 7 billion people?

The figure below shows that 4 one-inch segments are needed to make a 1 × 1 square, 12 one-inch segments are needed to make a 2 × 2 square composed of four 1 × 1 squares, and 24 one-inch segments are needed to make a 3 × 3 square composed of nine 1 × 1 squares. How many one-inch segments are needed to make an nx n square composed of 1 x 1 squares?

A family is building a new house on a rectangular lot of land. The lot measures 7x by 11x, and the house will be 2x by 3x. How much land will be left for their yard after the house is built?

Kamrie wants to paint her living room. The rectangular room measures 20 feet by 15 feet and has 10-foot ceilings. Along one of the long walls, there are three windows that each measure 3 feet by 8 feet. Along one of the short walls, there are two windows that each measure 3 feet by 8 feet. Along the other long wall, there is a rectangular opening that measures 7 feet by 8 feet. The cans of paint Kamrie will purchase cover 415 square feet. Determine the area of the doors, windows, and rectangular opening.

A scientist investigated the effect of​ cross-fertilization on the heights of plants. In one​ study, the scientist planted 15pairs of a species of plant. Each pair consisted of one​ cross-fertilized plant and one​ self-fertilized plant grown in the same pot. The table available below gives the height​ differences, in eighths of an​ inch, for the 15 pairs. Each difference is obtained by subtracting the height of the​ self-fertilized plant from that of the​ cross-fertilized plant. Use the paired​ t-interval procedure to determine a 99​% confidence interval for the difference between the mean heights of​ cross-fertilized and​ self-fertilized plants. Interpret the result.​ (Note: d=19.00 and sd=35.50​.)       The 99​%confidence interval is from ____ eighths of an inch to_____ eighths of an inch. ​(Round to two decimal places as needed. Use ascending​ order.)   Which statement below best interprets the confidence​ interval? A. There is 99​%confidence that the difference between the…
