What equation represents an exponential function that passes through the point (2, 80)?
Marina86 [1]

Answer:

f(x) = (4\sqrt{5})^{x}

Step-by-step explanation:

The exponential function looks like the following: f(x) = b^{x}.

If the function passes through the point (2, 80), then:

f(x) = b^{x} → 80 = b^{2}

Solving for 'b':

b = \sqrt{80} →b=4\sqrt{5}

Then, the equation of exponential function that passes through the point (2, 80) is: f(x) = (4\sqrt{5})^{x}

Consider a regular deck of cards with 52 cards in total. Four of a kind is a poker hand that contains all four cards of one rank
svet-max [94.6K]

Answer:

No.

Step-by-step explanation:

This is because if one event happens before the other, the odds of the other event happening will change due to less cards being left to pick from.

Consider the scenario where 4 of a kind all contained 10's from the deck.

The possibility of a full-house with a 10 in the pile would be zero if there were no 10's left after the four of a kind turn had been made. Thus, since the four of a kind affects the probability of the full house, and vice versa, they are both dependent on each other and hence not exclusive events.
