Abag contains 50 marbles,10 of which are blue ,8 are red,20 are green ,and 12 are purple . marcie takes a ow marble out of the bag ,records the color and returns
it to the bag how many red marbles should she expect after 500 trials

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
