Answer:

D. The inequality sign always opens up to the smaller number.

Step-by-step explanation:

Well if A says sign always opens up to larger number and D says sign always opens up to smaller number so 1 of them must be false. Inequality signs always open up to greater number so the answer is D.

Step-by-step explanation:

Let (x, y) be the point R

(x - 10)/2 = 3 and (y + 12)/2 = 7

x - 10 = 6 y + 12 = 14

x = 16 y = 2

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,

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

Solve for x. 4(2-x)+13=2x+3

gregori [183]

Answer:

x = 3

Step-by-step explanation:

4(2-x)+13=2x+3

distribute the 4.

8 - 4x + 13 = 2x + 3

combine like terms.

21 - 4x = 2x + 3

18 = 6x

divide by 6.

x = 3

check.

4(2 - 3) + 13 = 2(3) + 3

4(-1) + 13 = 6 + 3

-4 + 13 = 9

9 = 9

correct!

What is the value of this expression when n approaches infinity?

topjm [15]

ANSWER

C. 35

EXPLANATION

The given expression is:

$15 - 35 - \frac{85}{n} + 55 + \frac{75}{2n} + \frac{15}{2 {n}^{2} }$

$n \to \: \infty$

$\frac{k}{n} \to0$

where k is a constant.

This implies that,

$15 - 35 - \frac{85}{n} + 55 + \frac{75}{2n} + \frac{15}{2 {n}^{2} } = 15 - 35 - 0 + 55 + 0+ 0 =35$

The correct answer is C
