Answer:

John's commute = x + 0.5

Sheila's commute = 2x

Step-by-step explanation:

Given:

Total hour commute = 2

Mark's commute = x

John's commute = x + 0.5

Sheila's commute = 2x

Find:

Each commute

Computation:

Total hour commute = Mark's commute + John's commute + Sheila's commute

2 = x + x + 0.5 + 2x

4x = 1.5

x = 0.375  hour

John's commute = x + 0.5

John's commute = 0.375 + 0.5 = 0.875 hour

Sheila's commute = 2x

Sheila's commute = 2(0.375) = 0.75 hour

The lifetime of a machine part has a continuous distribution on the interval​ (0, 50​) with probability density function​ f, whe
Strike441 [17]

Answer:

Probability that the lifetime of the machine part is less than 13 = 0.6782

Step-by-step explanation:

given that f(x)=(10+x)^{-2}

Normalizing the function we get

\int_{0 }^{50}cf(x)dx=1

\int_{0 }^{50}c(10+x)^{-2}dx=1

\therefore a=\frac{1}{\int_{0 }^{50}(10+x)^{-2}dx}

\therefore a=12

P(x< 13)=\int_{0}^{13}12(10+x)^{-2}dx\\\\P(X< 13)=0.6782

Y=-6x + 5<br> x - y = 5
rodikova [14]

Answer:

y = \frac{-25}{7} or -3.571

x = \frac{10}{7} or 1.429

Step-by-step explanation:

x - y = 5

x = 5 + y

Solve for y:

y =  -6x + 5

y =  -6(5 + y) + 5  Substitute x with 5 + y

y = -6(5) - 6y + 5

y = -30 - 6y + 5

y + 6y = -30 + 5

7y = -25

y = \frac{-25}{7} or -3.571

Solve for x:

x = 5 + y

x = 5 + -25/7

x = \frac{10}{7} or 1.429
