Question 6 of 10 For a group experiment your science class measured the fine particulate
concentrations in the air at random places around campus, and estimated a
sample average of 32 ug/m (micrograms per cubic meter). If 225 readings
were taken, and the standard deviation of the sample measurements was
3 ug/m you are 99.7% confident that actual concentration of fine
particulates at the school is
A. 31.7 ug/m3 - 32.3 pg/m.
B. 31.4 ug/m3 - 326 ug/m
O G 26 pg/m2 - 38 ug/m3
D. 28 ug/m3 - 34 pg/m

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

the probability is 0

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
