Abag contains 4 green marbles, 6 red marbles, 14 orange marbles, 5 brown msrbles, and 8 blue marbles. you choose a marble, replace it, and choose again. what is p(red, then blue)?

Step-by-step explanation:

A bag contains 4 green marbles, 6 red marbles, 14 orange marbles, 5 brown marbles, and 8 blue marbles. You choose a marble, replace it, and choose again. Total marbles = 37 marbles

Probability (choosing red) = number of red marbles / total marbles

= 6/37

Red is replaces so total marbles again becomes 37

P( choosing blue)= 8/37

P(red, then blue)=

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

a .4y4

hope this !
