For this case we have:
Let a function of the form
By definition, to graph , where
, we must move the graph of f (x), h units to the left.
We observe that the red graph has the same form as the black graph, but it is displaced "h" units to the left.
It is observed that
So, if the black graph is given by, the red graph is given by:
Answer:
Option A
Answer:
Step-by-step explanation:
We know that:
In a deck of 52 cards there are 4 aces.
Therefore the probability of obtaining an ace is:
P (x) = 4/52
The probability of not getting an ace is:
P ('x) = 1-4 / 52
P ('x) = 48/52
In this problem the number of aces obtained when extracting cards from the deck is a discrete random variable.
For a discrete random variable V, the expected value is defined as:
Where V is the value that the random variable can take and P (V) is the probability that it takes that value.
We have the following equation for the expected value:
In this problem the variable V can take the value V = 9 if an ace of the deck is obtained, with probability of 4/52, and can take the value V = -1 if an ace of the deck is not obtained, with a probability of 48 / 52
Therefore, expected value for V, the number of points obtained in the game is:
So:
Let y represent the original price of a game.
<span>Ella purchased a game that was on sale 12% off which means that the new price of the game is 88% of the original price, so:
</span>
Next, t<span>he sales tax in her county is 6%, which means that the the now price is 106% to the original price, so:
</span>
. As a result, the final cost can represent under the form of 0.9328y. Hope it help!
