What is the IQR of 0,0,0,1,1,3,3,4,7,7

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

irrational, cannot

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.

x = 3 ± √(5+y)
