Answer:

Explanation:

Answer:

Explanation:

Answer:

Explanation:

In a the card game there are 4 groups N,E,W,S. Each group consist of 13 cards each

N: A,K,Q,J,10,9,8,7,6,5,4,3,2

E: A,K,Q,J,10,9,8,7,6,5,4,3,2

W: A,K,Q,J,10,9,8,7,6,5,4,3,2

S: A,K,Q,J,10,9,8,7,6,5,4,3,2

a) The number of ways player 1 receives 4 aces

Since 52 cards can be arranged in 52! ways

An A's card can be arranged in 4! ways

Number of possible arrangement of A's cards among the 4 player =( 52! / 4! )

So for 1 player to receive all the Ace's there will be (13!/4!) ways

13!/4! = 259459200 ways

b) each player receive 13cards of the same suit

There are 4! different ways to deal the cards so that each player gets all the cards of one suit.

The distribute 4 objects (suits) to the 4 players.

The number of ways to deal out the cards is (52!/13!) X (39!/13!) X (26! / 13!) X (13!/13!). You choose 13 cards to give to the first player, 13 to the second, 13 to the third and 13 to the fourth.

Using the rule for probability, you get an answer of

4! / ((52!/13!) X (39!/13!) X (26! / 13!) X (13!/13!))

Should organizations fear websites where consumers post negative messages about products or services? What actions can companies
pickupchik [31]

Answer:

This is something that actually helps organizations to improve their work and subsidiaries by people's real time assessement.

Explanation:

When consumers post negative messages, whether they are true or not, organizations have the opportunity to have an online conversation with consumers and provide help in real time communication. This improves communication within a company and with other subsidiaries by evaluating honest and threatening comments related to e-commerce real life development. There are a lot of people who do not use products according to the comments available on their marketing webpages, such as myself. These are all important for everyone to assess if it is worth to buy a product or not, and to keep up an online community in which people help each other by suggestions and recommendations, and organizations can take a lot of advantages from that, such as increasing their number of consumers.

3.A ball is thrown into the air with an initial velocity of 15 m/s. a.How long does it take the ball to reach maximum height?b.W
ehidna [41]

Answer:  a) = 1.5 sec.  b= 11.5 m. c=0  d= 1.5 sec.

Explanation:

a) Once thrown into the air , the only influence on the ball is gravity, so, we can conclude that the acceleration acting on the ball is the one due to gravity, i.e., g= 9.8 m/sec².

Applying the definition of acceleration, we can write the following equation:

a= (vf-vo) / t   ⇒ g = vf-vo / t. (1)

Now, when the ball reaches to his maximum height, it stops momentarily, and then starts to fall, so for this height, we can write vf=0.

Replacing  in (1), and solving for t, we get:

t = (0 -vo) / g = -15 m/s/ - 9.8 m/sec² (Taking upward as positive  direction)

a) t= 1.5 sec.

Replacing this value in the kinematic equation for displacement, when vo=15 m/s, we get:

hmax: 15 m/sec . 1.5 sec -1/2. 9.8 m/sec². (1.5 sec) ² (2)

b) hmax= 11.5 m

c) vf= 0 (as explained above)

Finally, in order to know how long the ball takes to return to its initial height, we know that for the falling part of the trajectory, vo=0, so we can write the equation for displacement as follows:

h=-hmax (because it returns to the same starting point)= 1/2 gt²=-11.5 m

Solving for t, we get:

d) t=1.5 sec.

It can be seen that the time used in going up, it is the same for going down, to travel the same distance.

This result is completely general and applies to any free fall problem.
