Mathematics

IRISSAK [1]3 years ago
5 0

Step-by-step explanation:

I assume the question is asking for Eric's grandfather age now.

Let Eric's age now be x. Then Eric's grandfather age now is (x + 55).

In 7 years, Eric's age will be (x + 7) and Eric's grandfather age will be (x + 62).

We know that (x + 62) = 6(x + 7).

x + 62 = 6x + 42

5x = 62 - 42 = 20

x = 4.

Answering the question: Eric's grandfather age now is (4 + 55) = 59 years old.

Refer to a standard deck of playing cards. Assume 5 cards are randomly chosen from the deck. How many hands contain 4 aces?
Setler79 [48]

There would be 0.07923 probability to get 4 aces.

<h3>What is probability ?</h3>

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Total number of cards in deck = 52

Total number of aces = 4

When 5 cards are chosen randomly,

The probability to get 4 aces

= 1/52+1/51+1/50+1/49+0

Since, at 5th time there will be no ace remains, so probability would be 0.

= 0.01923+0.01960+0.0200+0.0204

=0.07923

Question 3 of 12
vichka [17]

Answer:

See explanation

Step-by-step explanation:

Given

Needed = 19000

Required

Support the jeweler's conclusion

From the question, we have that:

Boxes = 48

Bead = 400 per box

So, he bought a total of:

Total = 48 * 400

Total = 19200

<em>Since, he needed exactly 19000 and he has 192000, we can conclude that he has enough beads</em>
