A standard deck of cards has 52 cards in four suits: spades, hearts, diamonds, and clubs. Spades and clubs are black; hearts and

Olegator [25]

Answer:

231

Step-by-step explanation:

Let's compute the probability of this event and then multiply it by 100.

As each deck has 4 suits and each suit has 3 faces, there are 12 faces in a deck.

As a deck has 52 cards, the probability of drawing a face is

This means that if you choose a card 1000 times from a deck of poker cards, you probably will select 231 times a face (rounding to the nearest integer).

If an object is propelled upward from a height of s feet at an initial velocity of v feet per second, then its height h after t

irina [24]

Answer:

At 1.5 seconds and 2.5 seconds

Step-by-step explanation:

Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.

$68=-16t^2+64t+8$

Set that equal to 0 and factor to solve for t:

$-16t^2+64t-60=0$

Using the quadratic formula, we get t = 1.5 and t = 2.5
