8 0

Answer:

2.48 × 10⁻⁵

Step-by-step explanation:

Number of people in the room of a different age = 8 people

The number of ways people can leave the room  = 8!

                                                                                 = 40320

They leave the room in ascending order is  = 1 way

The probability they leave the room in ascending order of their ages =

\frac{1}{40320} = 2.48 × 10⁻⁵

Given the cost function C(x) = 0.81x + 60, 420 and the revenue function R(x) = 1.87x, find the break-even point
Viktor [21]

Answer:

x = 57,542.8571

Step-by-step explanation:

C(x) = 0.81x + 60,420

R(x) = 1.87x

At break even point, Cost function and revenue function becomes equal.

-> C(x) = R(x)

-> 0.81x + 60,420 = 1.87x

-> 60420 = 1.87x - 0.82x

-> 60420 = 1.05x

-> x = 60420/1.05

-> x = 57,542.8571

Thus, at break even point x = 57,542.8571

y = 0.25x + 40

60 = 0.25x + 40

60 - 40 = 0.25x + 40 - 40

20 = 0.25x

\frac{20}{0.25}  =  \frac{0.25x}{0.25}

80 = x

Y = 2x + 1<br> y = 4x - 1<br> Solve by graphing
svet-max [94.6K]

Answer:

See attached graph

Step-by-step explanation:

Because both expressions are equal to y, they'll intersect each other at a certain point, which is the solution to the system of equations. In this case, as shown by the graph, the point of intersection is (1,3) which means x=1 and y=3.
