so get a tank of argon, spray that shit under the crack in the door like it's a russian theater, go upstairs to bed, and should be safe from fumes?

next morning, leave as normal, ditch the tank somewhere, come home to dead dad...

nice.

would prefer dry ice since much easier to source but i guess this could work

>It is plausible.

i'm worried that absent a sedative, the victim would just... struggle to breathe, wake up, and exit the bedroom or exit the car.

working on a horror script

hypothetically if i stuck dry ice in an enclosed space, how soon would someone be rendered unconscious?

if my character sleeps on a upper floor, could it be plausible they put some dry ice in a bucket next to their sleeping victim, retreat, and wait for them to expire then hold breath a bit to retreive bowl of evaporated dry ice and feign puzzlement the next morning that daddy didn't wake?

or is it quick enough you could say, put it in a car and just hold the door shut on the person having take their cell phone?

While you’re wrong on $4000 drones for Mars, you’re right that having unique robots for each mission is a dead-end. Once launch costs get significantly cheaper with starship we can plan to have a standard rover in sizes from 100kg, 1,000kg, 10,000kg and for gravities of 1-0.1g or 0.1-0.01g. That way we can have a finite set of choices and make TONS of them with massive economies of scale to make them cheap. You can also send them to many different planets and moons without significant rework.

If you have a network of more but less less powerful transmitters and recievers (maybe one in each planet’s 5 Lagrange points, so that even when the planet is on the other side of the sun the other relays are still close) you could use cheaper/lighter/less powerful stations because the signals wouldn’t need to go as far. It would also be more resilient to disruptions potentially.
I think we’re going to see a big update to the deep space network soon- once starship is operational.

You don’t need a masters in actuarial sciences to become an actuary. Get a job as an actuarial analyst at an insurance company with your bachelors degree (in math, Econ, doesn’t really matter- one of the best actuaries I worked with was a theater major, albeit with a math minor).
The company will pay you decent wages (I think ~60k starting about 10 years ago) and you get paid study time, time off to take actuarial exams, and they cover the exam costs). You stay in the program as long as you pass most exams (it’s ok to fail a few) You get raises/bonuses each time you pass an exam and a big jump when you hit ACAS and an even bigger jump at FCAS. At the company I was at, actuaries in training had a 6-12 month rotations to the various actuarial roles in the company. This was nice because you could figure out if you liked rate making or hated reserving etc.

Thanks a lot, i used the solver and realized where i was wrong

The solution is :

Let's solve your equation step-by-step.
(4x−6)2−(2x+1)(2x−1)=(2x−3)2
Step 1: Simplify both sides of the equation.
12x2−48x+37=4x2−12x+9
Step 2: Subtract 4x^2-12x+9 from both sides.
12x2−48x+37−(4x2−12x+9)=4x2−12x+9−(4x2−12x+9)
8x2−36x+28=0
Step 3: Factor left side of equation.
4(2x−7)(x−1)=0
Step 4: Set factors equal to 0.
2x−7=0 or x−1=0
x=
7
2
or x=1

The only part i didn't understand is (x−1) in part 3, where does it come from?

>>12109027
But the answer should be (1, 1/3), doesn't match with the values i got

>>12109023
I meant the values of a, b and c desu

Guys how do i solve 41 pls help, i get the values of 8 -36 and 27 for the quadratic equation, got something wrong on the way but can't figure it out

>>12108992
Thanks, but i seem to be doing something wrong here, a b and c values for the quadratic equation comes out wrong, i get 8 , -36 ,27
Pls halp

How the fuck do you solve 41

Trig functions, exponent rules, radicals, complex fractions, complex numbers, exponential function, function analysis

Are you good at DnD?
Are you good at math?
If you answered "yes" for at least one of those, maybe you can help me, because I can't.

I'm playing a multiclass character that is a fighter and also a warlock, I have the Elven Accuracy feat that allows me to play three dices to attack when I have advantage, I also can curse my target so 19 rolls will also be criticals, I have two attacks per round, but I also can use the feature "Action Surge" to gain more two attacks, four in total.

So, this is if you don't play DnD, before attacking an enemy, I roll a 20 sided dice to check if my hit will land, if the dice rolls 20, then I get a critical hit, if it rolls 19, I get a critical as well, which, at least in my mind, gives me a 2/20 (10%) of getting a critical hit, but I can roll three times and choose the best dice, so I guess I have (2+2+2)/20, or 6/20, now I must remember you that I have the second attack, which would give me three more chances to roll, so 12/20. But, then again, I can gain two more attacks, thus becoming 24/20, which would, theoretically, certainly hit a critical blow.

I know I'm wrong, I don't know why and where I got myself confused with those numbers. If you are willing to explain me, please, treat me as a child, but any internet video helping me with the question would also be really helpful. Someone once said to me that to get the right result, I must calculate the chances of NOT hitting 19 or 20, but I have no idea how to do that.

Thank you!

help me out

From what i know it is possible to determine hand dominance just by seeing an mri scan with a trained eye, does anyone know something about this?

Can any medfags estimate personality/sex/left or right handness just from this brain image?if so can you share what you can know about a person from a brain scan? Thx

what's your big think
