Answer: 1/15

Explanation:

Since it's a class of 6, and there are 2 students who forgot their lunch. The probability of firs choosing a student who forget their lunch will be 2 out of 6 which is 2/6.

When the next student who forget their lunch is picked there'll be 5 students left which means the probability then will be 1 out of 5 which is 1/5.

Therefore, the if the teacher chooses 2 students, the probability that both of them forgot their lunch will be 1/3 multiplied by 1/5 which will be:

= 1/3 × 1/5

= 1/15

A good reason to discuss why developing one is important to the success of a school government is it could create a safer, high qualified and more intelligent environment within the school walls. There could be possibilities in creating laws on bullying and it can positively affect everybody involved from hero through bully and victim through bystander. Setting ground rules can intimidate someone from doing something opposing. When there are consequences to positive and negative actions not only will it make people think twice about doing something wrong, but it will also encourage these people to step up and create a more positive atmosphere.

The equations of the tangent to the curve y=xsinx at the point (pi/2,pi/2) is

never [62]

The first thing you have to realize is that tangent is the slope of a curve on a given point. You can solve for the slope by finding the derivative of the given function. So:

$\frac{d}{dx} xsin(x)$

Next use product rule (I recommend watching videos if you're confused):

$= [sin(x)] + [x*cos(x)]$

Next substitute you x-value (π/2) into your derivative:

$= [sin( \frac{ \pi}{2} )] +[ \frac{\pi}{2}*cos( \frac{\pi}{2})]$
$= 1 + \frac{\pi}{2} *0$
$= 1$

So our slope at π/2 is 1. Next we use our slope-form and substitute our given value and solve for y-intercept (algebra-stuff)

$( \frac{\pi}{2}) = 1( \frac{\pi}{2}) + b$
$b = 0$

So we get our equation:

$y = x$

So our answer is E

Feel free to ask any questions.
