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,

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

Volume of sphere = 4/3 x pi x r^3

904.32 = 4/3 x pi x r^3

Divide both sides by 4/3

678.4 = pi x r^3

Divide both sides by pi:

216 = r^3

Take the cubic root of both sides

R = 6

Compute the product AB by the definition of the product ofmatrices, where Ab1 and Ab2 are computed separately, and by therow-

nasty-shy [4]

Answer:

$A * B = \left[\begin{array}{ccc}10&-6\\8&5\\19&-10\end{array}\right]$

Step-by-step explanation:

Given

$A =\left[\begin{array}{cc}2&-2\\3&4\\4&-3\end{array}\right]$

$B = \left[\begin{array}{cc}4&-1\\-1&2\end{array}\right]$

Required

$AB$

To do this, we simply multiply the rows of A by the column of B;

So, we have:

$A * B = \left[\begin{array}{ccc}2*4 + -2*-1&2*-1+-2*2\\3*4+4*-1&3*-1+4*2\\4*4-3*-1&4*-1-3*2\end{array}\right]$

$A * B = \left[\begin{array}{ccc}10&-6\\8&5\\19&-10\end{array}\right]$
