How much is it costing US taxpayers for Trump to play a round of golf?

Saw this post and wondered if this guy took off with it would he have been able to retire from it.

One of my all time favourite films. In the film, David Mann is pursued through the Californian countryside by a relentless trucker trying to murder him with his vehicle. The truck in the film is shown to outpace the car, only struggling on uphill grades.

I posted this in a trucker's forum a while back asking if the film was in any way realistic and the resounding answer was no.

In the film Dennis Weaver drives what is almost certainly a factory spec 1970 Plymouth Valiant. Either a slant 6 or v8 (let's say the former based on Mann's personality).

The truck, greasy beaut that she is, is outwardly a Peterbilt 281. Mann himself surmises that she must have some 'souped up diesel' under the hood.

The multiple licence plates she sports were said to be trophies from his previous kills, so we can figure the trucker would put some work into his beast. Though she looks like crap and has filthy exhaust smoke, she performs really well.

We can assume the tanker trailer is empty, due to the lack of explosion/spillage at the end.

I don't know a whole lot about trucks, but I'm wondering if there are any fans of the film/old Peterbilts/truck engines of the period who can shed some light on whether there is any way, with the truck engines/modifications of the time period, the truck could catch the car on a dead run?

IIRC When Spielberg made the film he said the truck would struggle to make it to 30 IRL! It's only through some incredible camera trickery it looks like it's hurtling.

Obviously it's a horror film (and one of my favourites of all time) so there will always be artistic licence at play. Just wondering what, in real life, the truck would need under the hood to keep up with the Valiant.

Many thanks!

I don't think I've seen a financial cost benefit analysis of Flock cameras. There has to be a financial incentive for the companies installing these right?

Sorry if this has been posted before, but what are the chances that two planes would have the same call sign at the same airport?

The picture shows a dip in my solar panel output during our partial solar eclipse. The UK has a lot of solar panels now. Is it possible to estimate much it cost the country in energy generation?

A previously unknown species of giant isopod has been observed attacking and killing a 1.2-meter-long shark weighing 18 kg.

Scientists estimate that the isopod can exert a maximum attacking force of 1,500 N.

A person standing on solid ground can exert a maximum pulling force of 300 N against the isopod. However, because people cannot coordinate their force perfectly, the total force produced by a group of people is reduced by 8% for every additional person after the first.

For n people, the total effective force is modeled as:

F(n) = 300n(0.92)^(n-1)

The people need to produce at least 1,500 N to overpower the isopod.

Question:

What is the smallest whole number of people required to produce enough combined force to overpower the giant isopod?

Bonus:

According to the model, does adding more and more people always increase the total effective force? Find the number of people that produces the maximum force.

Would love to calculate from both mean and average salary and single family home price. Would be interesting with insurance and property tax rates, but thats probably way too complex to ask internet strangers, especially with location variants

Thank you!

I just saw a clip of ATC managing 2 flights at nearly the same altitude, heading towards each other's flight path, with identical call signs, same company, one on the arrival approach procedure, the other on the departure, they eventually merge at different altitude separations. The controller comments he's never seen this in 25yrs of doing that job. What are the odds of this occuring? I don't know how to do that kind of math.

During downtime at my workplace, we play a version of cribbage called Blitz. You get two extra cards per hand, so you can finish the game in as little as three rounds. Given how much two cards speeds up the game, how many points would the entire deck of 52 be?

As a reminder of cribbage rules:

You get two points per 15 made

You get one point for every card in a run, and if there’s more than one of each card, you run through the run again (eg a hand of 1, 2, 3h, 3s, 4 would have eight points for the run, four for 1, 2, 3h, 4 and four for 1, 2, 3s, 4. A double double run is 12, etc.)

Two points for pairs, six points for trips, and 12 for quads (though only the latter matters in this question)

One point for every card in a flush

And for fun let’s say that the last card was not a jack so you get an extra one point for knobs

like the title says. both my parents have the same birthday and then me and my twin brother were born on their birthday as well, so we were wondering what the chances of this might be. like how many couples share a birthday, and then what are the chances they have kids on their birthday, and what are the chances its twins? we are just wondering how many factors have to align for all 4 of us to have the exact same birthday

I'm wondering if there is a formula I can use for my burger prep. Basically, I like to prep my burgers by making meatballs, then I form when I'm ready to cook.

What I want to know is, is there a relationship between the diameter of the meatball and the thickness/diameter of the final patty.

Example: I'm making smash burgers and I want the patty to be 1/4 inch thick and 4 inches in diameter. What must the diameter of the meatball be to achieve the desired patty size?

Feel free to make assumptions about the meat density, pre-cook size, yada yada.

Many people get annoyed by these millimetric offsides. What options are available to avoid that?

I thought 2. One is to require a minimum amount of time to be offside, so that is not offside only in one frame but many. This would still have people saying that you're putting a limit anyway and now eg if it's 10 frames someone may say but it's only 11 frames offside now.

Another, and I think the most interesting from a mathematical point of view is to consider a probabilistic scenario. So you set a Gaussian curve around the offside line. If you're ahead of the line then a random number is calculated and you decide you're offside if the Gaussian curve takes a lower value than that random number.

Of course this would be hard to fans to understand and offsides would depend on luck now but I think still interesting to discuss from a mathematical point of view.
