Gave some feedback: Needs to be tested

Gave some feedback: Ready to use

Saved a checkpoint:

I've done a lot of rewording, and added random names.

Saved a checkpoint:

I've reworded a bit.

Chris Graham commented on Cumulative percent decrease 8 years, 4 months ago

I've rewritten large parts of the advice, especially where visibility conditions were used, and utilised the random names extension to add some context to part b).

Christian Lawson-Perfect on Partial sum of an arithmetic sequence - birthday money 8 years, 4 months ago

Gave some feedback: Ready to use

Christian Lawson-Perfect on Partial sum of an arithmetic sequence - birthday money 8 years, 4 months ago

Saved a checkpoint:

Lots of little edits - I basically disagreed with every formatting choice you made!

This is a good question.

Christian Lawson-Perfect on Rounding and estimating calculations 2 8 years, 4 months ago

Saved a checkpoint:

I've split parts a and b into separate questions. I'm not sure about part c - is it obviousthat you'd always want to underestimate the distance? Maybe it needs a sentence like "you want to know if you'll meet your target in the next five minutes".

Gave some feedback: Should not be used

Christian Lawson-Perfect on Rounding and estimating calculations - painting a room 8 years, 4 months ago

Gave some feedback: Ready to use

Christian Lawson-Perfect on Rounding and estimating calculations - painting a room 8 years, 4 months ago

Saved a checkpoint:

I've split this off from a bigger question.

I've used the random names extension, rewritten the advice, and added a testing condition so that the exact amount of paint needed is never a whole number of buckets.

Changed the randomisation so that sometimes we do have enough money.

Used the currency function to display currencies, rather than formatting by hand.

Christian Lawson-Perfect on Find bounds for distance and time spent running, given imprecise measurements 8 years, 4 months ago

Gave some feedback: Ready to use

Christian Lawson-Perfect on Find bounds for distance and time spent running, given imprecise measurements 8 years, 4 months ago

Saved a checkpoint:

Rejigged a lot of the advice, and added steps to part a to make it abundantly clear that you need to calculate bounds for both the speed and the time taken.

It would be nice if the time was sometimes definitely lower or higher than the record, but I've spent long enough on this question already.

Christian Lawson-Perfect on Find bounds for distance and time spent running, given imprecise measurements 8 years, 4 months ago

Saved a checkpoint:

Used the random names extension, and split part b in two, so you can calculate the upper bounds before making the decision.

Needs some rewording to make it clear that the bounds come from the uncertainty in the average running speed.
