Answer:

Is it possible to pass a single vertical line through more than one point on the horizontal line?The answer to this question is: No it is not possibleSince we cannot have a vertical line cross through more than one point, this graph passes the vertical line test making it a function. Any input (x) leads to exactly one output (y)

Ask yourself this: Is it possible to pass a single vertical line through more than one point on the horizontal line?

The answer to this question is: No it is not possible

Since we cannot have a vertical line cross through more than one point, this graph passes the vertical line test making it a function. Any input (x) leads to exactly one output (y)

Answer:

2/3

Step-by-step explanation:

so the inverse takes us from the range to the domain... they tell us that f(4) goes to 5.. so if we were to take the inverse f $\left \[-1} \atop$ (5) it takes us back to 4... and the slope at 4 or the derivative was 2/3 so that's what we get for f $\left \ {{-1} \atop$ '(5) :)

Suppose James randomly draws a card from a standard deck of 52 cards. He then places it back into the deck and draws a second ca

qwelly [4]

Answer:

1.92%

Step-by-step explanation:

The probability for first case, picking a queen out of deck, will be:

$\frac{4}{52}$

as there will be 4 queens in a deck, one of each suit.

For the second pick, the probability of picking a diamond card, will be:

$\frac{13}{52}$

here the total will remain 52 as he has replaced the first card and not kept it aside and there will be 13 cards in diamond suit (including the three face cards).

Thus the net probability for both cases will be:

$P = \frac{4}{52} * \frac{13}{52}\\ P = \frac{1}{52}\\ P = 0.01923\\P = 1.923\%\\\\P = 1.92\%$

Thus total probability for the combined two cases will be 1.92%
