Compute the orthogonal projection of left bracket Start 2 By 1 Matrix 1st Row 1st Column negative 4 2nd Row 1st Column 5 EndMatrix right bracket onto the line through left bracket Start 2 By 1 Matrix 1st Row 1st Column negative 1 2nd Row 1st Column 1 EndMatrix right bracket and the origin. The orthogonal projection is left bracket Start 2 By 1 Matrix 1st Row 1st Column nothing 2nd Row 1st Column nothing EndMatrix right bracket . Bold y equals=left bracket Start 2 By 1 Matrix 1st Row 1st Column 3 2nd Row 1st Column 6 EndMatrix right bracket 3 6 and Bold uuequals=left bracket Start 2 By 1 Matrix 1st Row 1st Column 6 2nd Row 1st Column negative 6 EndMatrix right bracket 6 −6.
Write Bold y as the sum of two orthogonal vectors, one in Span Start Set Bold u End Set Span {u} and one orthogonal to Bold u.

When i add money am i supposed to make it like this 7+12 or 7.00+12.00 because i got 19 dollars for my answer

Tell whether the two rates form a proportion

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
