Discrete: possible number of ways of arranging odd numbers in odd position.

How many 7-digit naturals can be formed by catenating all of 1, 2, 2, 3, 3, 3, 4 if the odd naturals in this list must always occupy the odd positions?
the order be like for example 1, _, 3, _, 3, _, 3 where the odd numbers are in the odd positions. I know we have to use combinations. Is it correct?

Question: Is it possible to do student teaching at an online school?

I’m currently in a teachers prep program and it requires me to complete a 12-week clinical experience as a student teacher at a school of my choice.

With all the school shootings that have been happening, I’m honestly regretting my decision to become a teacher and am afraid to step into a classroom anymore. I can’t find any information regarding my question, but I was wondering if anyone here knows if it’s possible to do student teaching at an online school?

Serious answers, please.

P.S. When my program is over, I will be seeking employment at an online school and will only go in a real classroom if it’s the only job opportunity I get until I can find a new career path.

Is it possible to reparent child records?

Let me give you an outline of what I’m dealing with.

Parent records have an inactive/active value (picklist), some parent records share an external data value; SAP_Document_Number. I want to re-parent the child records of inactive parents to the active parent that shares the same SAP_Document_Number as the inactive parents records. IE there’s five inactive records that have the SAP_Document_Number of 5678123 there’s also a record listed as active that has an SAP_Document_Number of 5678123. I want those five inactive records to have all of their child records re-parented to the active record.

How they’re assigned is through a massive mess of apex triggers/handlers. So i’d rather do this using process automation —> to flow if possible. But I’ve yet to see examples online of anyone attempting something similar…my googlefu has failed. If someone has seen something similar please share it with me.

Is it possible to obtain someone’s private IP through IP logging?

Let’s say Alice sends Bob a link through email, social media etc. The link logs Bob’s IP if Bob clicks the link.

If I’m correct, the IP Alice gets is Bob’s public/ISP IP address. Is it possible for Alice to obtain Bob’s private/client IP with only a link, or does Alice have to do more than that to obtain Bob’s private IP (Evil twin for example).

I also assume that this all becomes obsolete if Bob uses a VPN to mask his identity.

Is it actually possible to obtain someones private IP through IP logging

Let’s say User A sends User B a link through email, social media etc. that logs User Bs IP if User B clicks the link. Now if I’m correct, the IP User A gets is User Bs public/ISP IP address. Is it possible for User A to obtain User Bs private/client IP with only a link, or does User A have to do more than that to obtain User Bs private IP(Evil twin for example). I also assume that this all becomes obsolete if User B uses VPN to mask his identity.

Is it possible to build a secure PRG from two functions one of them being a PRG?

Having two deterministic functions $G_1, G_2 : left{0,1right}^lambda rightarrow left{0,1right}^{lambda+l}$, at least one of which is a secure PRG.

Being $alpha$ a constant, is it possible to build a secure PRG $G’ : left{0,1right}^{alpha*lambda} rightarrow left{0,1right}^{alpha*(lambda+l)}$ using $G_1$ and $G_2$?

My intuition is that it can’t be done, but I don’t know how to prove it.
