You want to compute a 80% confidence interval for the mean of a population with an unknown population standard deviation. The sample size is 25. What will be the degrees of freedom?

What could explain what happened when the time was equal to 120 minutes

Factor -8x3-2x2-12x-3 by grouping what is the resulting expression?

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.
