Answer:

Approximately 10.2 inches

Step-by-step explanation:

The area of a square is given by the formula:

$A=s^2$

Where A is the area and s is the side length.

Since we already know that the area A is 105, substitute:

$105=s^2$

Now, take the square root of both sides:

$s=\sqrt{105}$

Use a calculator:

$s\approx10.2470$

So, the side length is approximately 10.2 inches.

(12x + y + z = 26

mel-nik [20]

Option D. D has the matrix of constants [[12], [11], [4]].

Step-by-step explanation:

Step 1:

With the given equations, we can form matrices to represent them.

The coefficients of x, y, and z form a matrix of order 3 ×3, the variables x, y, and z form a matrix of order 1 ×3 and the constants form a matrix of order 1 ×3.

Step 2:

The linear system A is represented as

$\left[\begin{array}{ccc}12&1&1\\1&-11&0\\1&-1&4\end{array}\right]$ $\left[\begin{array}{ccc}x\\y\\z\end{array}\right]$ $= \left[\begin{array}{ccc}26\\17\\23\end{array}\right]$ .

Step 3:

The linear system B is represented as

$\left[\begin{array}{ccc}4&1&1\\1&-11&0\\1&-1&12\end{array}\right]$ $\left[\begin{array}{ccc}x\\y\\z\end{array}\right]$ $= \left[\begin{array}{ccc}23\\17\\26\end{array}\right]$ .

Step 4:

The linear system C is represented as

$\left[\begin{array}{ccc}1&1&1\\1&-1&0\\1&-1&1\end{array}\right]$ $\left[\begin{array}{ccc}x\\y\\z\end{array}\right]$ $= \left[\begin{array}{ccc}4\\11\\12\end{array}\right]$ .

Step 5:

The linear system D is represented as

$\left[\begin{array}{ccc}1&1&1\\1&-1&0\\1&-1&1\end{array}\right]$ $\left[\begin{array}{ccc}x\\y\\z\end{array}\right]$ $= \left[\begin{array}{ccc}12\\11\\4\end{array}\right]$ .

Step 6:

Of the four options, the linear system D has the matrix of constants [[12], [11], [4]]. So the answer is option D. D.

The length of an instant message conversation is normally distributed with a mean of 5 minutes and a standard deviation of .7 mi

Charra [1.4K]

The <em><u>correct answer</u></em> is:

0.0764

Explanation:

We will use a z-score to answer this. The formula for a z-score is

$z=\frac{X-\mu}{\sigma}$ , where μ is the mean and σ is the standard deviation. Using our information in this problem, we have

$z=\frac{6-5}{0.7}=\frac{1}{0.7}=1.43$

Using a z-table, we look up the z-score 1.43. The area under the curve to the left of, or less than, this value is 0.9236. This means the probability that the time is greater than this is 1-0.9236 = 0.0764.
