Just took one of those thinly veiled IQ tests for a job application and I got one of those number sequences that you're supposed to find the next in the sequence for but I don't think there was a correct answer

Here is the sequence: 5, 3, 9, 13, 23

Baby girl what? I was running out of time so I clicked 37 which has to be wrong but I'm so confused

Are kims arms.. 1.3m long... a 2.6m wingspan. The the real cryptids are the friends we make along the way

Wingspan is measured from fingertip to fingertiwp which includes the length of the hands (0.5m) and the breadth of the back (1.1m) which aren’t accounted fo by the 1.3m figure, which measures sleeve length (arm length) only, so the real wingspan is probably something more like 2(0.5) + 1.1 + 2(1.3) which comes out to 3.4m (π)

3 hour study session☕️

taking the first longer break since I started at 3.30pm. after dinner ill probably continue with solving math problems. at least I got the latin presentation done. my head is hurting but I’m motivated :‘)

update, 10:30pm: switched to working on my term paper about an hour ago, google docs is making me loose my mind. But at least I finally have some words written down.

to do: solve math problems / study for exam

Adult math problem:

My doctor appointment is at 4:30, it's a 23 minute bus ride away but the bus stop is an 11 minute walk from here. The bus runs every 30 minutes and I want to be at the clinic 15 minutes early. What time should I leave work so that I can sit in the waiting room for 2 hours because the doctor is behind schedule?

A math problem I heard about, that I thought you might find interesting:

We have a burger patty, and a ketchup packet.

We don't know how much ketchup is in the packet - the only way to know is to use it all.

What's the optimal path we can draw on the burger patty, in order to minimize the average shortest distance to ketchup for any given point on the patty?

Extra details:

The path does not have to be continuous, it's allowed to have breaks.

You're not allowed to spread the ketchup once it's placed.

You can't place an infinitely small amount of ketchup on a given timestep. It can be arbitrarily small, but it has to deduct some measurable amount of ketchup from the packet.

Yes, the objective is ambiguous. For example, we haven't defined whether we're optimizing for the worst case, best case, or average case. We also haven't decided whether or not the ketchup trail has width. Pick whichever parameters seem most interesting.

The patty is circular, although solutions for other shapes would also be interesting.

It's a vegan patty. Other condiments are also acceptable.

Can anyone make a proof of these

I too lazy to try.
