Upper and Lower Bounds

[xDaDivax]

Glad I stopped the video to look at comments, the upper bound for 450 to the nearest 10 is 455, I need to doubt myself less, please fix that

[jazeirwie]

I'm pretty sure that the upper bound is 455 not 465.

I am absolutely sure the UB for 450 is 455. Well spotted.

[sikaawe]

Lower bound = 445
Actual number =450
Upper bound = 455

Thank You, i know understand upper and lower bounds, it never got into my head but it has now

[crypticgamerz]

the last question you did is wrong, I checked the answer in my textbook which has the same exact question and it says that the answer is 8.75

What would be an upper bound for 30cm that has been rounded to 2 significant figures

[rocketlauncher]

was helpful thanks, you did better than the mathswatch lady

[gooeynick]

Lower bound of 3.1 to 2 significant figures???

[arunkumararunkumar]

For the number 6.99 correct to 2 decimal place find upper bound and lower bound

[evienell]

this video really helped me, apart from the upper bound of 450 is 455 not 465

[majorobalino]

Ain't 165.5 LB=165.54 and UB 165.56?

[Chrisymcmb]

So you add another significant figure from what the problem mentions?

[jamiebarclay]

yea the upper bound is not half way btw, if it was 5.5 for example you would round it to 6 not 5

[ibodulloturaev]

FIND THE UPPER BOUND OF 234 TO THE NEAREST 10?
Who can send answer plz

[MOHIBeAALeRASOOL]

Your UB of 450 is wrong it should be 455

[evabakerio]

Was revising when I noticed that 465 isn't the highest bound for 450. Pheww

[trexz]

it said 1dp and you did 2 dp then it said 2dp and you did 3dp

All of this is so wrong. Please, if you plan on teaching, properly educate yourself first.
Cheers.
