Assume the sample is from a normally distributed population and construct the indicated confidence intervals for (a) the population variance
Suppose that the augmented matrix for a system of linear equations has been reduced by row operations to the given row echelon form. Solve the system by back substitution. Assume that the variables are named
At the specified position, determine the vectors T, N, and B.
and point
The reduced row echelon form of the augmented matrix of a system of linear equations is given. Determine whether this system of linear equations is consistent and, if so, find its general solution.
Write the solution in vector form.
Use the given graph of f to find a number
h is related to one of the parent functions described in this chapter. Describe the sequence of transformations from f to h.
Determine whether the planes are parallel, perpendicular, or neither. If neither, find the angle between them. (Round to one decimal place.)
