Please help. attached question

OpenStudy (anonymous):

Will you upload under .pdf file?

OpenStudy (anonymous):

ill try

OpenStudy (anonymous):

OpenStudy (anonymous):

First 30-min range: d lower: 0 d upper: 13 * 30 = 390 m/h

OpenStudy (anonymous):

lower estimate cant be 0

OpenStudy (anonymous):

In your lecture, time can't be 0?

OpenStudy (anonymous):

its asking distance not time

OpenStudy (anonymous):

distance = speed * time!

OpenStudy (anonymous):

yea but its done in a weird way. its not asking just the lowest interval or the highst interval

OpenStudy (anonymous):

Should you upload your notes so I can compare?

OpenStudy (anonymous):

I'm researching on net now!

OpenStudy (anonymous):

i don't have online notes

OpenStudy (anonymous):

but i may be able to show u the book notes

OpenStudy (anonymous):

Anything that help me to catch up what level you are is fine :)

OpenStudy (anonymous):

thanks! one sec

OpenStudy (anonymous):

there will be two files because it all doesnt fit on the screen

OpenStudy (anonymous):

:)

OpenStudy (anonymous):

this is lower estimate or wahtever

OpenStudy (anonymous):

OpenStudy (anonymous):

upper

OpenStudy (anonymous):

OpenStudy (anonymous):

I'm sort of getting the idea :)

OpenStudy (anonymous):

okay thanks! I got all of the files attached here

OpenStudy (anonymous):

Don't worry, I'll finish up! Just do whatever you want, then I'll show you how to!

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

Because Roger's speed is decreasing: Upper estimate distance for the first 30 min: 15min ( 15 + 14 ) = 435 mi Lower estimate distance for the first 30 min: 15 min ( 13 + 14 ) = 405 mi Upper estimate distance for the whole 90 min: 15 min ( 15 + 14 + 13 +13 + 11 + 10) = 1140 mi Lower estimate distance for the whole 90 min: 15 min ( 0 + 10 + 11 + 13 + 13 + 14 ) = 915 mi

OpenStudy (anonymous):

Hey, it takes so long, somehow my internet connection so unstable!

OpenStudy (anonymous):

thank you! ill try it out

OpenStudy (anonymous):

:)

OpenStudy (anonymous):

hm it says itis wrong. I

OpenStudy (anonymous):

All wrong?

OpenStudy (anonymous):

it doesnt say which one or if all is :( but i remember get 1140 my last tim for something

OpenStudy (anonymous):

How about switch lower upper!

OpenStudy (anonymous):

but that does not make much sense i dont think

OpenStudy (anonymous):

I got 1140 for the upper!

OpenStudy (anonymous):

After calculation, I see it makes sense, because the speed is decreasing!

OpenStudy (anonymous):

i don't know :( i just had to get all new values and this is my last chance.

OpenStudy (anonymous):

Are you sure you enter correctly? because in the question, the lower estimate goes first while my answer the upper estimate goes first!

OpenStudy (anonymous):

yea i made sure of that

OpenStudy (anonymous):

You did answer in right order already?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

i got all new values :(

OpenStudy (anonymous):

I'm recalculating!

OpenStudy (anonymous):

well i have new stuff :(

OpenStudy (anonymous):

new numbers

OpenStudy (anonymous):

Something wrong with my calculator!

OpenStudy (anonymous):

hope not lol

OpenStudy (anonymous):

Because the result different!

OpenStudy (anonymous):

its okay. I got new numbers anyway

OpenStudy (anonymous):

The method is exactly right! All you do make sure the calculation correctly!

OpenStudy (anonymous):

ok ill try it again thanks

OpenStudy (anonymous):

Do you want to upload, so you can compare your answer!

OpenStudy (anonymous):

i just dont think its doen right fo some reason

OpenStudy (anonymous):

upper is adding that extra value at the end. whatever it is i think

OpenStudy (anonymous):

The idea is estimate from right end or left end!

OpenStudy (anonymous):

its not ends. lower is all of them calculated not including last interval and upper is including last interval

OpenStudy (anonymous):

Exactly!

OpenStudy (anonymous):

Did you see the set of numbers I entered just different at the left or right end!

OpenStudy (anonymous):

im confused im sorry but it didnt look like the examples. its okay! thankyou for trying and giving ur time.

OpenStudy (anonymous):

In the example, it has total 6 sets!

OpenStudy (anonymous):

When they estimate lower/ upper: they calculate 5 sets!

OpenStudy (anonymous):

hmm you might be right. I was confused. shouldi show you my new examples or i could just try it soon

OpenStudy (anonymous):

Go ahead, I'd like to clarify it to you!

OpenStudy (anonymous):

ok one sec

OpenStudy (anonymous):

I'll make sure triple check my calculation this time!

OpenStudy (anonymous):

ur awesome thanks here it is

OpenStudy (anonymous):

OpenStudy (anonymous):

Lower estimate distance for the first 30 min: 15 min ( 14 + 15 ) = 435 mi Upper estimate distance for the first 30 min: 15min ( 16 + 15 ) = 465 mi Lower estimate distance for the whole 90 min: 15 min ( 15 +14 +14 + 12 +11) = 990 mi Uppper estimate distance for the whole 90 min: 15 min ( 16 +15 + 14 +14 + 12 + 11) = 1230 mi

OpenStudy (anonymous):

are ya confident :)

OpenStudy (anonymous):

Yep!

OpenStudy (anonymous):

i think the book mislead u. It's not always six boxes, this one is seven boxes. I feel like lower would be 15(16+15+14+14+12+11) and upper would be 15(15+14+14+12+11+0)

OpenStudy (anonymous):

i didnt plug in yet becasue this is my last chance.

OpenStudy (anonymous):

No matter how many sets, the idea is just enter n -1 sets from left or right!

OpenStudy (anonymous):

I know and I already tested my number over and over!

OpenStudy (anonymous):

ok ill do it! haha

OpenStudy (anonymous):

it was wrong :( its okay i cant do it anymore times. But you were great. I'll give u points

OpenStudy (anonymous):

I really don't need point! All I want is helping you out :(

OpenStudy (anonymous):

well ur awesome for being so nice. I can't do any more of it

OpenStudy (anonymous):

I believe the system malfunction! You can complain about it with your teacher!

OpenStudy (anonymous):

well thank you!

OpenStudy (anonymous):

My friends have the same problem while taking the online quizzes.

OpenStudy (anonymous):

yea it sucks. Thanks so much though ur great.

OpenStudy (anonymous):

Talk to him, you'll see!

OpenStudy (anonymous):

Good luck!

OpenStudy (anonymous):

thanks!
