A small wireless store offers three different cell phone plans to anyone who buys one of the five phones the store carries. The store is giving away a free gift to anyone who chooses one of the three plans and buys one of the listed phones. The table below shows the cell phone plans, the cell phone types, and the available free giftsWhat is the probability that a customer selects the two-year contract, a smart phone, and a $25 gift certificate

the answer will be the last one

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.
