What is the probability of rolling two dices whose sum is prime

Mathematics
1 answer:
Nuetrik [128]3 years ago
7 0

The logic is there are six sides to each die, so for each number on one die you can pair with six different numbers on the other die. Therefore, the probability of rolling a prime number on two dice is 15/36, which reduces to 5/12.

You are given the following information: Stockholders' equity = $323 million; price/earnings ratio = 14; shares outstanding = 8,
vagabundo [1.1K]

Answer:

$282.59 per share

Step-by-step explanation:

Given that,

Stockholders' equity = $323 million

price/earnings ratio = 14

shares outstanding = 8,800,000

Market/book ratio =7.7

Book Value per share:

= Stockholders' equity ÷ shares outstanding

= $323,000,000 ÷ 8,800,000

= $36.70

Market price per share:

= Book Value per share × Market/book ratio

= $36.70 × 7.7

= $282.59 per share

A ferry departs from a port along the Sands River at 10:00 am. The ferry travels at a speed of 15 mph in still water and returns
jek_recluse [69]

Answer:

Speed of river's current = 5 mph

Step-by-step explanation:

Let 'd' be the distance covered  

 Let x be the speed of the rivers current

Speed upstream = 15-x

speed downstream = 15+x

Time = distance / speed

time upstream = \frac{d}{15-x}

time downstream = \frac{d}{15+x}

the ferry trip upstream takes twice as long as its return trip downstream

\frac{d}{15-x}= \frac{2d}{15+x}

divide both sides by d

\frac{1}{15-x}= \frac{2}{15+x}

cross multiply

15+x= 2(15-x)

15+x= 30-2x

Add 2x on both sideds

15+3x= 30

subtract 15 from both sides and divide by 3

3x=15

x=5

Speed of river's current = 5 mph
