Answer:

$x = - 12$

C.E.: x <em>=/=</em> -4

Step-by-step explanation:

$\frac{x}{x + 4} = \frac{4}{x + 4} + 2 \\ \frac{x}{x + 4} = \frac{4 + 2x + 8}{x + 4} \\ x = 4 + 2x + 8 \\ - x = 12 \\ x = - 12$

A college financial adviser is interested in studying the number of students at his college who apply for loans when entering gr

Shalnov [3]

Answer:

0.7429

Step-by-step explanation:

Given that Of the 721 students at the college, 299 of them apply for loans when entering graduate school.

So p = proportion of students applying for loans = $\frac{299}{721} =0.415$

Each student is independent of the other and there are two outcomes

Hence out of 45 students the no of students who apply for loans say X is binomial with n =45 and p = 0.415

the probability that more than 16 of them apply for loans

= $P(X>16)\\= \Sigma_{x=17} ^{45} P(x)\\=\Sigma_{x=17} ^{45}(45Cx (0.415)^x (0.585)^{25-x} )$

=0.7429

$\large\underline{ \boxed{ \sf{✰\:Important\: point's }}}$

➣ Circle:- A two-dimensional geometric figure, a line, consisting of the set of all those points in a plane that are equally distant from a given point (center).
➣ Circumference:- The line that bounds a circle or other two-dimensional figure

${ \rule{70mm}{2.9pt}}$

★ also circumference of a circle is also known as it's perimeter

➣To find circumference of circle when use formula

${ \boxed{✜\underline{ \boxed{ \sf{\: Circumference \: of \: circle= \: 2\pi \: r}}}✜}}$

➢ r = radius (25inch.)
➢ value of π is 3.14

${ \rule{70mm}{2.9pt}}$

$\large\underline{ \boxed{ \sf{✰\: Let's\:solve }}}$

$\sf{➛ \: Circumference \: of \: circle = 2 \times 3.14 \times 25} \\ \sf{➛ \: Circumference \: of \: circle =2 \times 78.5} \\ \sf{➛ \: Circumference \: of \: circle =157inch}$

★ Hence circumference of circle=157inch

$\large\underline{ \boxed{ \sf{➪\:157inch. }}}$

${ \rule{70mm}{2.9pt}}$

Hope it helps !

Solve for A R=x(A+B)

julia-pushkina [17]

R=x(A+B)
divide both sides by x
R/x=A+B
minus B both sides
(R/x)-B=A
A=(R/x)-B
