What is a sampling ratio?
It is the ratio between the size of the sample and the size of the population.
What are two different size squares that the ratio of their perimeters is the same as the ratio of their areas?
Assume square A with side a; square B with side b. Perimeter of A is 4a; area of A is a2. Perimeter of B is 4b; area of B is b2. Given the ratio of the perimeters equals the ratio of the areas, then 4a/4b = a2/b2; a/b = a2/b2 By cross-multiplication we get: ab2 = a2b Dividing both sides by ab we get: b = a This tells us that squares whose ratio of their perimeters equals the ratio of their areas have equal-length sides. (Side a of Square A = side b of Square B.) This appears to show, if not prove, that there are not two different-size squares meeting the condition.
How do you calculate compression ratio?
compression ratio = compressed size / uncompressed size the ratio should be between 1 and 0 (multiply with 100 to get the ratio in percent) a ratio greater than 1 means, the compressed size is actually greater than the uncompressed size a ratio just below 1 means bad compression the lower the ratio, the better the compression
What is the relationship between the surface area to volume ratio of a cell and its size?
The larger the surface area to volume ratio of a cell, the smaller its size (and vice versa).
How do you find the ratio of an object?
You cannot. You can only find a ratio of two or more objects. Then, it can be the ratio of their size, volume, mass, monetary value, temperature - or any other characteristic that can be measured.
