Stephen read 121212 books, 202020 magazines, and 171717 newspaper articles last year. Based on this data, what is a reasonable estimate of the probability that Stephen's next reading material is a magazine?

41%

Step-by-step explanation:

So you need to find the probability first:

12+20+17=49

There are 20 magazines:

20/49=0.4081

That rounded would be 0.41.

Now you need to get rid of the decimal point:

0.41×100=41

41%

Hope this helped!

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
