If a normal distribution has a mean of 132 and a standard devistion of 20, what is the value that has a z score of 3.6

nika2105 [10]

z = (x - μ)/σ

Substituting given values, you have

3.6 = (x - 132)/20

(20)(3.6) = x - 132 . . . . multiply by 20

72 + 132 = x . . . . . . . . .add 132

204 = x

The value that has a z-score of 3.6 is 204.

Find the determinancof the matrix Q.

stepan [7]

Using a Laplace expansion along the first column, we have

$\det Q=2\det\begin{bmatrix}2&1\\-1&6\end{bmatrix}+3\det\begin{bmatrix}3&4\\-1&6\end{bmatrix}+5\det\begin{bmatrix}3&4\\2&1\end{bmatrix}$

The determinant of a 2x2 matrix is trivial,

$\det\begin{bmatrix}a&b\\c&d\end{bmatrix}=ad-bc$

So we have

$\det Q=2\cdot13+3\cdot22+5\cdot(-5)=67$
