Based on experience, the time required to complete a college statistics exam is normally distributed with a mean of 42 minutes and a standard deviation of 8 minutes. The class is a large lecture and has 900 students. Simulate the exam completion times for the 900 students. (Convert to a percent then round to two decimals) a) What percent of students are still working when the professor stops the exam at 50 minutes

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

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
