Vector is quantity that has magnitude and direction.

One example of a vector is acceleration.

Let us now tackle the problem !

$\texttt{ }$

This problem is about Vector Diagram.

$\overrightarrow{OA} = \overrightarrow{a}$

$\overrightarrow{OC} = \overrightarrow{c}$

X is the midpoint of the line AC:

$\overrightarrow{x} = \frac{1}{2} (\overrightarrow{a} + \overrightarrow{c})$

$\texttt{ }$

OC : CD = k : 1

$k \overrightarrow{CD} = \overrightarrow{OC}}$

$k( \overrightarrow{d} - \overrightarrow{c} ) = \overrightarrow{c}}$

$( \overrightarrow{d} - \overrightarrow{c} ) = \frac{1}{k} \overrightarrow{c}}$

$\overrightarrow{d} = \overrightarrow{c} + \frac{1}{k} \overrightarrow{c}}$

$\overrightarrow{d} = ( 1 + \frac{1}{k} ) \overrightarrow{c}}$

$\texttt{ }$

$\overrightarrow{XD} = 3 \overrightarrow{c} - \frac{1}{2} \overrightarrow{a}$

$\overrightarrow{d} - \overrightarrow{x} = 3 \overrightarrow{c} - \frac{1}{2} \overrightarrow{a}$

$( 1 + \frac{1}{k} ) \overrightarrow{c} - \frac{1}{2} (\overrightarrow{a} + \overrightarrow{c}) = 3 \overrightarrow{c} - \frac{1}{2} \overrightarrow{a}$

$( 1 + \frac{1}{k} - \frac{1}{2}) \overrightarrow{c} - \frac{1}{2} \overrightarrow{a} = 3 \overrightarrow{c} - \frac{1}{2} \overrightarrow{a}$

$( \frac{1}{k} + \frac{1}{2}) \overrightarrow{c} - \frac{1}{2} \overrightarrow{a} = 3 \overrightarrow{c} - \frac{1}{2} \overrightarrow{a}$

$\frac{1}{k} + \frac{1}{2} = 3$

$\frac{1}{k} = 3 - \frac{1}{2}$

$\frac{1}{k} = \frac{5}{2}$

$k = \frac{2}{5}$

$\texttt{ }$

The resistance for resistors of a certain type is a random variable Xhaving the normal distribution with mean 9 ohms and standar

Y_Kistochka [10]

Answer:

$P(8.6$

And using the normal standard distirbution or excel we got:

$P(-1$

Step-by-step explanation:

Let X the random variable that represent the resistance for resistors of a population, and for this case we know the distribution for X is given by:

$X \sim N(9,0.4)$

Where $\mu=9$ and $\sigma=0.4$

We are interested on this probability

$P(8.6$

And the z score formula is given by:

$z=\frac{x-\mu}{\sigma}$

Using this formula we got:

$P(8.6$

And using the normal standard distirbution or excel we got:

$P(-1$
