Jerome's body mass index will fall between 19 and 31 for the set of all weights such that ___ Round to the nearest tenth as needed.
I came up with 25> 700W/75(2 to the power) =
25 • 75(2 to the power) > 700W over 75(2 to the power) x 75(2 to the power) =
25 •(5625) > 700W
140,625 > 700W = 200.893 - 201 rounded to the nearest tenth
which will equal a body mass index I = 25.
Now I have to figure out the solution of __ Could anyone please help me with this answer. Thank you so much
