Answer:
Check the explanation
Step-by-step explanation:
Since each and every one of the 4 hallways is equally likely then
Now, if he chooses H1 he escapes after 12 minutes then
If he chooses H2 then he wastes 10 minutes and then he is again in the same starting
position so he expects to escape in E(T) minutes, then
Analogously, if he chooses H3 then he wastes 40 minutes and then he is again in the same starting
position so he expects to escape in E(T) minutes, then
Therefore
So we have
Therefore he is expected to escape in 72 minutes
Answer:
108 ft
Step-by-step explanation:
point slope form
y-y1 = m(x-x1)
y-5 = -2/15(x--5)
y-5 = -2/15 (x+5)
change to slope intercept form
distribute
y-5 =-2/15x -10/15
y-5 = -2/15x -2/3
add 5 to each side
y = -2/15x -2/3 + 5
y = -2/15x -2/3 + 15/3
y = -2/15x +13/3
