How do I complete the square but with cubes and cuboids?

How come on the last problem (4) the answer is 5 and not -5?

Example 5:

Your answer for the mean is wrong in part a. I'm pretty sure you don't need to make it negative. I think the mean should be 150.3

Bien, y tu?

okay!

Can I just please say something? Have you been sent by God on earth to save the lives of us IB students? Or, perhaps, make the life easier?

No, I am serious. I am as serious as can be. Are you an angel or something? Is there something I can do for you? like… I dont know, send you 50 packets of chocolate, or maggi or… whatever.

I dont even know how to say thank you or appreciate this website because I dont have words or the perfect terminology for this website.

It is beyond good, and perfect.

:) hehe… Thanks a lot!

I've had a few requests for that… Sorry just don't have the time. However!

There is a print option at the bottom of the page. You may be able to print to a pdf.

please please please, if you have chance, add any math hl videos! my class of '17 is the first class in the entire school's history to receive the IB diploma! they even warned us that the program will not be okay and we're the experimental class (the lab rats). by the way, my school and only 2-3 others in the entire city have this iB program. any help you're able to give us, I'll be more than grateful! thank you!

Question 6 - Part b. 72 is one standard deviation away, but 90 is not. 88 would be 1 standard deviation away.

Yes it should be 'right', not 'left'. I was just going to post that here.
