At a stop sign, some drivers come to a full stop, some come to a rolling stop' (not a full stop, but slow down), and some do not

Natasha2012 [34]

Answer:

Option C.

Step-by-step explanation:

Given information:

Male-Full stop = 6, Male-Rolling stop = 16, Male-No stop = 4

Female-Full stop = 6, Female-Rolling stop = 15, Female-No stop = 3

Using the given information we get

Total number of males = 6 + 16 + 4 = 26

Total number of males = 6 + 15 + 3 = 24

Probability of No stop is

$p=\dfrac{\text{No-stop}}{Total}$

$p=\dfrac{4+3}{50}$

$p=\dfrac{7}{50}$

We need to find the number of males that would we expect to not stop at all.

Expected number of males = Number of males × Probability

Expected number of males = $26\times \dfrac{7}{50}$

Expected number of males = $3.64$

Therefore, the correct option is C.

Derivative of<br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7B3x%7D%5E%7B2%7D%20-%202x%20-%201%20%7D%7B%20%7Bx%7D%5E%7B2

Answer:

$\displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3}$

Step-by-step explanation:

we would like to figure out the derivative of the following:

$\displaystyle \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} }$

to do so, let,

$\displaystyle y = \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} }$

By simplifying we acquire:

$\displaystyle y = 3 - \frac{2}{x} - \frac{1}{ {x}^{2} }$

use law of exponent which yields:

$\displaystyle y = 3 - 2 {x}^{ - 1} - { {x}^{ - 2} }$

take derivative in both sides:

$\displaystyle \frac{dy}{dx} = \frac{d}{dx} (3 - 2 {x}^{ - 1} - { {x}^{ - 2} } )$

use sum derivation rule which yields:

$\rm\displaystyle \frac{dy}{dx} = \frac{d}{dx} 3 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2}$

By constant derivation we acquire:

$\rm\displaystyle \frac{dy}{dx} = 0 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2}$

use exponent rule of derivation which yields:

$\rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ - 1 -1} ) - ( - 2 {x}^{ - 2 - 1} )$

simplify exponent:

$\rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ -2} ) - ( - 2 {x}^{ - 3} )$

two negatives make positive so,

$\displaystyle \frac{dy}{dx} = 2 {x}^{ -2} + 2 {x}^{ - 3}$

<h3>further simplification if needed:</h3>

by law of exponent we acquire:

$\displaystyle \frac{dy}{dx} = \frac{2 }{x^2}+ \frac{2}{x^3}$

simplify addition:

$\displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3}$

and we are done!

Solve the equation g^2-12g=-36

Tresset [83]

$\bold{Answer}$

$\boxed{\bold{G \ = \ 6}}$

$\bold{Explanation}$

$\bold{Solve: \ g^2-12g=-36}$

$\bold{---------------------}$

$\bold{Add \ 36 \ To \ Both \ Sides}$

$\bold{g^2-12g+36=-36+36}$

$\bold{Simplify}$

$\bold{g^2-12g+36=0}$

$\bold{Solve \ With \ Quadratic \ Formula}$
$\bold{a=1,\:b=-12,\:c=36:\quad g_{1,\:2}=\frac{-\left(-12\right)\pm \sqrt{\left(-12\right)^2-4\cdot \:1\cdot \:36}}{2\cdot \:1}}$

$\bold{\left(-12\right)^2-4\cdot \:1\cdot \:36 \ = \ 0}$

$\bold{g_{1,\:2}=\frac{-\left(-12\right)\pm \sqrt{0}}{2\cdot \:1}}$

$\bold{g=\frac{-\left(-12\right)}{2\cdot \:1}}$

$\bold{Simplify \ \frac{-\left(-12\right)}{2\cdot \:1} \ = \ 6}$

$\bold{g=6}$

$\boxed{\bold{Eclipsed}}$
