Sally’s bag of marbles contains 10 red, 12 blue, and 3 green marbles. She conducted an experiment in which she pulled out one marble and recorded the color then returned it to the bag 50 times. Her results are shown in the table. What is the difference between the experimental probability and the theoretical probability of picking a red marble?

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

8 2/3 is the answer

step-by-step explanation: just use a calculator

step-by-step explanation:

cats

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
