For this case we must raise an inequality.
We have "d" dollars initially and they are spent 12. Then:
At least 51 dollars remain, then, the sign of inequality is greater or equal in favor of the expression, that is:
Resolving:
There are at least 63 dollars left in the account.
Answer:
Answer:
d = 483.56 inches
Step-by-step explanation:
We have,
Radius of a bicycle tire is 11 inches. It is required to find the distance traveled by the distance covered by the tire when it makes 7 revolutions. One revolution means the circumference of circle. So,
In 7 revolution, it will cover a distance of 7C i.e.
So, the tire will cover a distance of 483.56 inches in 7 revolutions
Answer:
The probability that he ends up with a full house is 0.0083.
Step-by-step explanation:
We are given that a gambler has been dealt five cards—two aces, one king, one 3, and one 6. He discards the 3 and the 6 and is dealt two more cards.
We have to find the probability that he ends up with a full house (3 cards of one kind, 2 cards of another kind).
We know that gambler will end up with a full house in two different ways (knowing that he has given two more cards);
Only in these two situations, he will end up with a full house.
Now, there are three kings and two aces left which means at the time of drawing cards from the deck, the available cards will be 47.
So, the ways in which we can draw two kings from available three kings is given by = {∵ one king is already there}
= {∵
}
= = 0.0028
Similarly, the ways in which one king and one ace can be drawn from available 3 kings and 2 aces is given by =
=
= = 0.0055
Now, probability that he ends up with a full house =
= = <u>0.0083</u>.
