A.)Two particles, both carrying charge 3 C are traveling
parallel to each other with velocities of v⃗ =17000i^v→=17000i^ in
m/s. They are positioned at the points (0,3,0)(0,3,0) and
(0,−3,0)(0,−3,0). What is the magnitude and direction of the
magnetic field at (0,3,0)(0,3,0) due to the particle located at
(0,−3,0)(0,−3,0)? [Enter the magnitude in answer box 1 and the
direction as one of either "in", "out", "up", "down", "left", or
"right" in answer box 2. Assume that the xx-axis corresponds to
left/right,...

An investigator has a 50-item scale and wishes to compare two
groups of participants on the item scores. He has heard about
MANOVA, and realizes that the items will be correlated. Therefore,
he decides to do a two-group MANOVA with each item serving as a
dependent variable. The scale is administered to 45 participants,
and the investigator attempts to conduct the analysis. However, the
computer software aborts the analysis. Why? What might the
investigator consider doing before running the analysis?

Consider
f(x, y) = (x ^2)y + 3xy − x(y^2)
and point P (1, 0).
Find the directional derivative of f at P in the direction of ⃗v
= 〈1, 1〉. Starting from P , in what direction does f have the
maximal rate of change? Calculate the maximal rate of change

Does the line with equation (x, y, z) = (5, -4, 6) +
u(1,4,-2) lie in the plane with equation (x, y, z) = (3,
1, 2) + s(1,2,-1) + t(2, -1, 1)? If it does not lie on this
plane you must solve for where it intersects. Justify your answer
algebraically. If the line does not lie on the plane what
is the angle between them?

In 2014, a leading financial services provider conducted a
survey in order to determine how Americans are planning for
retirement. Of the 1,041 adults aged 18 years and older who were
included in the survey, 243 said they were currently not saving
anything for retirement. Based on this information, the 95%
confidence interval for the proportion of all adults who are
currently not saving for retirement would be which of the
following?
