B. ​Stem-and-leaf plots can compare quantitative data to qualitative​ data, unlike histograms.​ However, they are not very useful for large data sets. C. ​Stem-and-leaf plots are easier to make and can contain more information than histograms.​ However, they are not very useful for large data sets. D. ​Stem-and-leaf plots are more useful for large data sets and can display more information than histograms.​ However, they are more difficult to construct.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2

choice b

the answer is x=45 because i said so
