Step-by-step explanation:
Based on 100 trials, we don't expect the experimental probability to deviate much from the theoretical probability. The scales on the attached graphs are hard to read, but you want to choose the graph that ...
- has bars that total 100 in their length
- has bars that are approximately .50, .25, .17, .08 in height, corresponding to the area fraction
We think the appropriate choice may be C, but we cannot tell for sure.
Answer:
- Exact distance =
feet
- Approximate distance = 127.2792 feet.
===========================================================
Explanation:
The area of the square is 8100 square feet, abbreviated ft^2.
Apply the square root to find the distance from any base to its adjacent counterpart (eg: from 1st to 2nd base). So we get sqrt(8100) = 90 ft as that side distance. Notice that 90*90 = 8100.
If you were to draw a line from 1st base to 3rd base, then you would split the square into two congruent right triangles. Each right triangle is isosceles (the two legs being 90 ft each).
Use the pythagorean theorem to find the hypotenuse.
The distance from 1st to 3rd base is roughly 127.2792 feet.
