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,

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

Giovanna owns a farm. She is going to randomly select one animal to present at the state fair. She has 6 pigs, 7chickens, and 10

Arada [10]

Answer:

The answer to your question is P(chicken) = 0.30

Step-by-step explanation:

Data

number of pigs = 6

number of chickens = 7

number of cows = 10

P(chicken) = ?

Process

1.- Sum up all the number of animals

Total animals = 6 + 7 + 10

= 23

2.- Calculate the probability

P(chicken) = number of chicken / total number of animals

-Substitution

P(chicken) = 7/23

-Simplification

P(chicken) = 0.30

The terminal arm of an angle drawn in standard position rotates in a positive direction through two quadrants of the coordinate

miskamm [114]

There are 4 quadrants and each quadrant is has a measure of 90° angle.

Because the direction is positive, it means that the arm is going from 1st quadrant to 2nd quadrant.

90° + 90° = 180°

Because there is an additional rotation of 25°, the arm is now in the 3rd quadrant.

180° + 25° = 205°

The measure of the angle is 205°
