In a missile-testing program, one random variable of interest is the distance between the point at which the missile lands and t

Arisa [49]

Answer:

Step-by-step explanation:

From the given data

we observed that the missile testing program

Y1 and Y2 are variable, they are also independent

We are aware that

$(Y_1)^2 and (Y_2)^2$ have $x^2$ distribution with 1 degree of freedom

and $V=(Y_1^2)+(Y_2)^2$ has x^2 with 2 degree of freedom

$F_v(v)=\frac{e^{-\frac{v}{2}}}2$

Since we have to find the density formula

$U=\sqrt{V}$

We use method of transformation

$h(V)=\sqrt{U}\\\\=U$

There inverse function is $h^-^1(U)=U^2$

We derivate the fuction above with respect to u

$\frac{d}{du} (h^-^1(u))=\frac{d}{du} (u^2)\\\\=2u^2^-^1\\\\=2u$

Therefore,

$F_v(u)=F_v(h-^1)(u)\frac{dh^-^1}{du} \\\\=\frac{e^-\frac{u^-^}{2} }{2} (2u)\\\\=e^-{\frac{u^2}{2} }U$

Anvisha [2.4K]

Answer:

True: 1, 4, 5

Step-by-step explanation:

Main notations:

A plane is a flat 2D surface with no thickness that extends infinitely far. (Option 1 is true)

A point is an exact location. It has no size, no width, no length, no depth, only position. (Option 2 is false)

Collinear points are two or more points that lie on the same line and have different location. (Option 3 is false)

A line is straight (no bends), has no thickness, and extends in both directions without end (infinitely). (Option 4 is true)

The distance between two points is the length of a line segment that connects them. (Option 5 is true)
