The probability of a dry day is 1/8 If it is a dry day, the probability that Blake cycles to work is 5/14 that he drives to work is 5/14
and that he takes the train to work is 2/7
If it is a wet day, the probability that Blake cycles to work is 3/16 that he drives to work is 1/4 and that he takes the train to work is 9/16

Determine the probability that Blake takes the train to work. (CREATE A TREE DIAGRAM IN YOUR NOTES AND USE IT TO SOLVE THIS PROBLEM)

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

the answer is 489

step-by-step explanation:

45

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
