The electric potential in an electric field is given by
V(x, y, z)= (-9.40 V/m5)x3y2 + (3.85 V/m4)y4 - (9.8 V/m2)zy.
Determine the unit vector form E = [ Ex V/m)i + (Ey V/m)j + (Ez
V/m)k] of the electric field at the point whose coordinates are
(-1.3 m, 2.3 m, 3.1 m). Give the x, y, z components of electric
field in the form "+/-abc" V/m, or, "ab.c" V/m as is appropriate.
For example, if you calculate the electric...

20 women and 30 men between 18 to 60 years old and the
number of hours that they work. These information would be your
populations. For each group find the followings:
20 Women Ages = 19, 23, 40, 18, 60, 50, 21, 30, 33, 28,
33, 35, 28, 24, 28, 18, 19, 22, 25, 50
20 women work hours weekly = 40, 24, 30, 31, 19, 10, 21,
5, 40, 9, 8, 40, 37, 12, 20, 40, 20, 10, 40,...

Consider the observations jointly taken on the binary random
variables X and Y given in the “Problem 1” worksheet in the Excel
spreadsheet titled “Sheet 1”.
1. Organize the data in a two-way table by counting the number
of observations that fall within each of the following cells: {X =
0, Y = 0}, {X = 0, Y = 1}, {X = 1, Y = 0}, and {X = 1, Y = 1}.
2. Use observed cell counts found in...

A child jumps off a wall from an initial height of 16.4 m and lands
on a trampoline. Before the child springs back up into the air the
trampoline compresses 1.8 meters. The spring constant...
