I got 0. 

Why: To find the mean of a set of numbers, you need to add all the numbers that are given. Once you find the numbers that are given, divide by the amount of numbers given. Basically, add -1, 4, 0, -1, -1, -1, then divide the outcome by 6.

Message me for more help if needed.

Kevin has already read 45 pages in his novel for English. He can read roughly 20 pages each hour. Shania has only read 5 pages s
jolli1 [7]

Answer:

Shania has read the most pages.

Step-by-step explanation:

Following the formula y = mx + b.

Kevin already read 45 pages.

y = mx + 45

He reads 20 pages per hour, since it has per hour, we put it has "m"

y = 20x + 45

Shania already read 5 pages

y = mx + 5

Shania reads 25 pages per hour

y = 25x + 5

We need to find out how many pages they read after 20 hours, plug 20 into x.

Kevin

20(20) + 45 =

400 + 45 =

445

Shania

25(20) + 5 =

500 + 5 =

505

Shania read 60 more pages than Kevin.

HELP ME ASAP I HAVE SO MANY QUESTIONS THAT WILL SAY THIS BUT HELP MEEE!!!(timed!!)
tester [92]

Answer:

1. $8.30

Step-by-step explanation:

so 3 hats were purchased and each cost 15.50 so

15.50*3=46.50

and the rest of the 96.30 is 6 keychains so

96.30-46.50=49.80

and there is 6 keychains

49.80/6=8.30

Each key chain was $8.30

Claire's answer is unreasonable because when we got the price of the keychains all together in Claire's mind the total for the keychains would be $4.98, which we clearly got the total for the keychains at $49.80.
