Mathematics
1 answer:
Alinara [238K]2 years ago
3 0

Answer:

let Karen's music library be represented by K

let Clarann's music library be represented by C

C = K +18

C +K =40

put C = K +18 into (C +K =40)

K + 18 +K =40

2K +18 = 40

collect like terms

2K =40 -18

2K =22

divide both sides by 2

K =11

since C = K+18

C= 11 +18

C =29

Karen's music library contains 11 playlists while Clarann's music library contains 29 playlists

What assumption have you made in answering part b​
emmasim [6.3K]

You're assuming that this data set represents all of Mrs. Hassaan's pupils. Certain students could be missing from the histogram - for instance, there could be one or two students who missed the test, but for certain reasons will be taking a make-up exam. Their grade would not be recording in this data set, but they still contribute to the class size, and so would be unaccounted for here.
