Two trains are 500 miles apart when they first enter a collision course. If, after two hours, the distance between them is 300 m
deff fn [24]
60 miles per hour. In two miles the sum of the distance the two trains traveled was 200 miles, you divide that by 2, the sum of the speed of the two trains is 100 miles per hour, now put the speed of the slow train as  x and the fast as x +20, the sum of x and x +20 is 100, so 2x + 20 =100, you subtract 20 from both sides, 2x = 80, divide by 2, x = 40, the problem asks for the speed of the fast train, so, x + 20 is 60.

1. y and x have a proportional relationship, and y = 7 when x = 2. What is the value of x when y = 21?
Alex

Answer:

Proportional relationship states that one in which two quantities vary directly with each other.

In other words, we say the variable y varies directly as x if:

  y = kx , where k is constant of proportionality.

(1)

Given: y and x varies a proportional relationship, and y = 7 and x=2

find the value of x when y =21

By the definition of proportional relationship;

y = kx                  ......[1]

Substitute the value y= 7 and x = 2 to solve for k;

7 = 2k

Divide by 2 to both sides we get;

\frac{7}{2} =\frac{2k}{2}

Simplify:

k = 3.5

Now,  substitute the value of k = 3.5 and y =21 in equation [1] to find the value of x.

21 = 3.5 x

Divide both sides by 3.5 we get;

\frac{21}{3.5} =\frac{3.5x}{3.5}

Simplify:

x = 6

Therefore, the value of x is 6.

(2)

Given: y and x varies a proportional relationship, and y = 9 and x=2

find the value of y when x=3.

By the definition of proportional relationship;

y = kx                  ......[1]

Substitute the value y= 9 and x = 2 to solve for k;

9 = k\cdot 2

Divide by 2 to both sides we get;

\frac{9}{2} =\frac{2k}{2}

Simplify:

k = 4.5

Now,  substitute the value of k = 4.5 and x=3 in equation [1] to find the value of y.

y= 4.5 \cdot 3

Simplify:

x = 13.5

Therefore, the value of y is 13.5.

(3)

From the given table,

y = 2.8 when x = 2

by the definition of proportional relationship;

2.8 = k \cdot 2

or

2.8 =2k

Divide by 2 to both sides, we get;

\frac{2.8}{2} =\frac{2k}{2}

Simplify:

k = 1.4

Therefore, the equation that represents the table is; y = 1.4 x

Jobs arrive at the server at the rate of 8 jobs per hour. The service takes 3 minutes, on the average. This system is modeled by
Gemiola [76]

Answer:

2249 / 540000

Step-by-step explanation:

Jobs arrival time = 8 jobs per hour

Service takes 3 minutes on average

Frame size = 5 second

capacity of each frame = 3 jobs

<u>Determine the transition probability matrix for number of jobs in system </u>

First step : find probability of job arrival

= 8 / ( 5 * 3600)

=  8 / 18000 =  1 / 2250

next : determine probability of service

= ( 3 * 5 )/ 3600

= 15 / 3600 = 1/240

Finally the transition probability matrix ( p10 )= { 1, 0}

=  probability of service(1 - probability of arrival)

 = 1/ 240 * ( 1 - 1 / 2250 )

= 1 / 240 * ( 2249 / 2250 )

= 2249 / 540000
