Let y1, y2,... , yn denote a random sample of size n from a population with a uniform distribution on the interval (0,theta). le

t y(n) = max{y1,y2,...,yn} and u = (1/theta)y(n). (a) show that u has distribution function fu(u) = { (b) because the distribution of u does not depend on theta, u is a pivot. find a 95% lower confidence hound for theta.

7 divided by 4 x + 3 Y + 4 divided / 4 x minus 3 Y is equal to 5 / 4

Answer:

  (x, y) = (4, 4)

Step-by-step explanation:

If you attempt to solve this by clearing fractions, you end up with an extraneous solution. Here, we'll solve the linear equations ...

  7a +4b = 5/4

  8b -14a = 3/2

where a = 1/(4x+3y) and b = 1/(4x-3y)

Dividing the second equation by 2 and adding the first, we have ...

  (7a +4b) +1/2(8b -14a) = (5/4) +1/2(3/2)

  8b = 8/4

  b = 1/4

Substituting into the first equation gives ...

  7a +4/4 = 5/4

  a = 1/28

__

Now, we can get back to solving for x and y.

  4x +3y = 1/a = 28

  4x -3y = 1/b = 4

  8x = 32 . . . . . . . . . add the two equations

  x = 4

  3y = 28 -4x = 28 -4(4) = 12 . . . . . use x in the equation for 'a'; rearrange

  y = 4 . . . . divide by 3

The solution to the system of equations is (x, y) = (4, 4).

_____

<em>Additional comment</em>

If you graph these equations, you find they describe hyperbolas that intersect at (0, 0) and (4, 4). The "solution" (0, 0) is extraneous, as both equations are undefined there.

How long (to the next whole year) will it take
fomenos

Step-by-step explanation:

2x = x1.2^n

2 = 1.2^n

log1.2(2) = n

log10(2)/log10(1.2) = n = 3.801784017...

so, rounded to the next whole year it takes 4 years.

Answer:

519.6

Step-by-step explanation:

A hexagon has a total of 720 for it's interior angles so each angle is 120 and in the triangle, each of them is 60, making it an equilateral triangle. You can use 30 60 90 triangles to find the height which is 5√3.

(5√3)*10=50√3

The area of the triangle times 6 is 300√3 which is approximately 519.6
