Elian heard that spinning a coin on a flat surface-rather than flipping it-made the probability of the coin landing
showing "heads" something other than 50%. To test this theory, he spun a nickel a series of 80 times and
observed that p = 60% of the spins landed showing "heads."
To see how likely a sample like this was to happen by random chance alone, Elian performed a simulation. He
generated a sample of n = 80 spins where each spin had a 50% chance of showing "heads," and he recorded
what proportion of spins in the sample showed "heads." He repeated this process for a total of 125 samples.
Here are the sample proportions from his 125 samples:

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
