The mean weight of 15 members of a company is 58kg. One more member whose weight is 74kg joins the company. Find the new mean weight of the members​

59kg

Step-by-step explanation:

58kg * 15 members=870

870+74kg=944

944/16 total people =59kg

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
