to exercises 4.141 and 4.137. suppose that y is uniformly distributed on the interval (0, 1) and that a > 0 is a constant. a
Elis [28]

The moment-generating function for y is given as eⁿᵇ - eⁿᵃ / n(b-a) and derivation of  moment-generating function of y is e-1/t

Given that,

The interval (0, 1) is covered by a uniform distribution of y, and a > 0 is a constant.

The moment generating function is eⁿᵇ - eⁿᵃ / n(b-a)

The given interval is (0,1)

Here a =0;

         b=1;

Now substitute the values of a and b in the above moment generating function we get,

y=eⁿᵇ - eⁿᵃ / n(b-a)

y=e^1-e^0/t(1-0)

y= e-1/t

Therefore, the derivation of the moment generating function is e-1/t

A rectangular field with perimeter of 80m is to have an area of at least 380m² . Describe the possible lengths and of the field.
Kryger [21]

let \: x \: be \: the \: length \\ let \: y \: be \: the \: width

perimeter = 2x + 2y \\ area = xy

2x + 2y = 80 \\ xy = 380 \\  \\ x + y = 40 \\ xy = 380 \\  \\ x = 40 - y \\ (40 - y)y = 380

40y - y {}^{2}  = 380 \\ y {}^{2}  - 40y + 380 = 0 \\  y {}^{2}  - 40y + 400 = 20 \\ (y - 20) {}^{2}  = 20 \\ y  - 20 =± \sqrt{20}  \\ y_{1}=20-√20≈15.52786\\ y_{2}=20+√20≈24.4721

morpeh [17]

Answer:

650/per hour

Step-by-step explanation:

I got this answer by dividing 1,625 by the amount of hours it took to fill that much water, 2.5 so basically i divided 1,625/2.5 to get my answer.
