Trent wanted to know if there was a connection between his coffee consumption and how well he slept that night.

for weeks, trent recorded how many cups of coffee he drank in the morning and how many hours he slept that night. the probability that a day is one when he drank exactly 1 cup of coffee is 0.71, the probability that it is one when he slept exactly 8 hours is 0.61, and the probability that it is one when he drank exactly 1 cup of coffee or is one when he slept exactly 8 hours is 0.89.

what is the probability that a randomly chosen day is one when he drank exactly 1 cup of coffee and is one when he slept exactly 8 hours?

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

i reviewed this question with a peer and teacher, seems to be correct, me later

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
