Answer:

4.5 It doesn't come out evenly, but cross products do work.

Step-by-step explanation:

She is not correct.

50 * x = 3 * 75              Combine the right

50x = 225                    Divide by 50

x = 225/50

x = 4.5

A state vector X for a four-state Markov chain is such that the system is four times as likely to be in state 2 as in 4, is not
GREYUIT [131]
All the components in the state vector need to sum to 1. You're given that component corresponding to state 1 is 0.2, and that the component for state 3 is 0.

That leaves states 2 and 4, for which you're told that the component for state 2 is four times as large. If x_i is the component for state i, then you have

x_1+x_2+x_3+x_4=1\iff 0.2+4x_4+0+x_4=1\implies5x_4=0.8\implies x_4=0.16

which means x_2=4x_4=0.64. So the state vector is \mathbf x=(0.2,0.64,0,0.16).

A company’s total cost from manufacturing and selling x units of their product is given by: y = 2x^2 – 600x + 49,000. How many u
AysviL [449]

Answer:

number of units for cost to be minimum=150

Step-by-step explanation:

y=2x^2-600 x+49000

dy/dx=4x-600

dy/dx=0 gives 4x-600=0

4x=600

x=150

d^2y/dx^2=4x

at x=150,d^2y/dx^2=4*150=600>0

so y is minimum at x=150

I dont understand the problem
Roman55 [17]

Answer:

equation of a line:

y = mx+c

1) find the gradient, m

m =  \frac{y2 - y1}{x2 - x1}

m =  \frac{ - 4 - ( - 4)}{ - 10 - 1}

m = 0

2) find y-intercept, c using coordinate (1,-4)

y = mx + c

-4 = 0(1) + c

c = -4

the equation of line:

y = mx+c

y = 0(x) + c

y = c

y = -4
