The ages of three siblings Jason John and Jackson totals 21 years. Jason is one year older than John. Jackson is three times as
Ymorist [56]

Answer:Jason is 5 years old.

John is 4 years old.

Jackson is 12 years old.

Step-by-step explanation:

Let x represent the age of Jason.

Let y represent the age of John.

Let z represent the age of Jackson.

The ages of three siblings Jason John and Jackson totals 21 years. It means that

x + y + z = 21 - - - - - - - - - - -1

Jason is one year older than John. It means that

x = y + 1

Jackson is three times as old as John. It means that

z = 3y

Substituting x = y + 1 and z = 3y into equation 1, it becomes

y + 1 + y + 3y = 21

5y = 21 - 1 = 20

y = 20/5 = 4

x = y + 1 = 4 + 1

x = 5

z = 3y = 3 × 4

z = 12

Find the probability that when 200 reservations are accepted for united flight 15, there are more passengers than seats availabl
Arlecino [84]

The solution for this problem is:

We know the problem has the following given:

Sample size of 200

X = 182

And the probability of .9005; computation: 1 - .0995 = .9005

 

So in order to get the probability:

P (x >= 182) = 1 – 0.707134 = .292866 is the probability that when 200 reservations 
are recognized, there are more passengers showing up than there 
are seats vacant.

The other solution is:

p (>= 182) = p(183) + P(184) + P(185) + ... + P(199) + P(200) = 0.292866
