Answer:
0.216
Step-by-step explanation:
If the probability of green, P(green) is 40%, the probability of red, P(red) is 60%.
The probability of a light being red is not affected by the colour of the previous light, so at each of the 3 lights, the probability of red is always 60%.
To find the probability that all three lights will be red, multiply the three probabilities together. (Convert them to decimals first).
0.6 x 0.6 x 0.6 = 0.216
0.2 is rounded to the nearest tenth
Answer:
32 n
Step-by-step explanation:
I had the same problem but I used a net force calculator the formula is F=MA so it would be 32=16/2.0 :)
Answer:
80 hours
Step-by-step explanation:
let d represent doug, let l represent laura
first, set up a system of equations representing the problem:
since doug spent 10 less than twice the hours laura did, and we know that the total amount of hours they spent together is 230:
l=2d+10
d+l=230
then solve:
*first i rearranged the equations so i can solve this system of equations using elimination method*
l-2d=10
l+d=230
*subtract*
3d=240
d=80
so, doug spent 80 hours in the lab
