Skyler goes to a school which has 1000 students in it. she asks 40 random students whether they like the new 8.30am start to the day. 30 of them say "no" they do not like it. use the information to estimate how many students in the whole school dislike the 8.30am start.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
