A student said that the median car rolled between 30 and 40 cm. Do you agree or disagree? Explain.

yes

Step-by-step explanation:

given no other information that must be the median i mean it seems to be obvious seeing that it went between 30 and 40 cm

yes

Step-by-step explanation:

because a median will take place in between the given measurement  

the median between 30 and 40 would be 35 seeming as it is in the middle

therefore i would agree with the student

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.
