thanks!!

Answer 1

graph!

first 10 days of march :)

Answer 2

#1: The average temperature increased from March _______ (what day?) to March ______ (what day?). The average temperature decreased from March ______ to March ________.

^^not really sure on this one... what do I do first? :/

#2: Find a pair of consecutive intervals over which the average temperature was increasing at a decreasing rate. Find another pair of consecutive intervals over which the average temperature was increasing at an increasing rate.

**answer choices attached here.... A,B,C,D,E from top to bottom :)

not sure about this one either! please explain!! thanks :)

Answer 3

srry, i dont have the time for something this involved :/

Answer 4

okay no worries :) thanks for coming though!! :)

Answer 5

good luck :)

Answer 6

thanks!! :)

Answer 7

I think by "average temperature" they mean the temperature given for a specific day.
from day 5 to day 9 it increased

Answer 8

ohh okay I see :)

yeah i got really confused by what they meant by average temperature... :/

so it's decreasing from day 5-2??

Answer 9

oh sorry, from 2-5? or 1-5? :/

Answer 10

decreases from day 2 to day 5

Answer 11

okay @phi is it because 1 and 2 are the same temp?

@Loser66 are you talking about #2? :/

Answer 12

yes, I am sorry, didn't see phi's reply

Answer 13

yes same temp means neither increase or decrease...

I have not yet checked my thoughts against the choices

Answer 14

haha okay :)

are we on #2 now? :/

Answer 15

and it's okay @Loser66 :)

Answer 16

let phi have it done. :)

Answer 17

hahaa alrighty :)

Answer 18

to answer Q2, write the difference in temperature between days.

Answer 19

oh okay...

1-2 = stayed the same

2-3=decrease by 8 degrees

3-4=decrease by 9 degrees

4-5=decrease by 3 degrees

5-6= increase by 12 degrees

6-7=increase by 4 degrees

7-8=increase by 2 degrees

8-9=increase by 9 degrees

9-10=stayed the same


did i do that right? :/

Answer 20

yes, but I would just use -8 for decrease by 8 and +12 for increase by 12.
it is easier to type.

now to answer:
pair of consecutive intervals over which the average temperature was increasing at a decreasing rate

Answer 21

so between days 5-8, it increased,

and 7-9, it increased as well?

Answer 22

oh and 5-8 the rate of increase was of a smaller margin and 7-9 it jumped up more?

Answer 23

I am trying to decipher what "a pair of consecutive intervals" mean

I assume pair means 2, and consecutive means next to each other
so
5-6 +12
6-7 +4 which shows an increase, but the increase is slowing down
7-8 +2 now we have 3 intervals in a row where it's increasing at a slowing rate

we also have
7-8 + 2
8-9 +9 an increase for both days, but the rate is increasing.

Answer 24

ohh okay... so would it be this choice?

Between March 5 and March 8 , the average temperature increased, but the rate of increase went down. Between March 7 and March 10, the average temperature increased, and the rate of increase went up.

?? :/

Answer 25

I think that is very close, but the last choice sounds better.

Answer 26

ohh okay yeah that makes more sense :)

because at 9-10, there's not increase right? :)

Answer 27

yes, that is my thinking. However, I am confused by what they mean by pairs of consecutive intervals, and what "between days 7 and 10" really means.

I really don't like these kinds of questions where the asker (allegorically speaking" mumbles some cryptic question. In person, I would tell the asker, when you learn to communicate, I'll get back to you on this one..

Answer 28

okie :) thanks!! yeah i was so confused by the phrasing :/

okay sounds good :)
