A project’s critical path is composed of activities A (variance .33), B (variance .67), C (variance .33), and D (variance .17).

julia-pushkina [17]

Answer:

The standard deviation on the critical path = 0.834

Step-by-step explanation:

Variance of activity A ( $V_{1}$ ) = 0.33

Variance of activity B ( $V_{2}$ ) = 0.67

Variance of activity C ( $V_{3}$ ) = 0.33

Variance of activity D ( $V_{4}$ ) = 0.17

Thus the standard deviation on the critical path ( $\alpha ^{2}$ ) = $V_{1} ^{2}$ + $V^2_{2}$ + $V^2_{3}$ + $V^2_{4}$

$\alpha ^{2}$ = $0.33^{2}$ + $0.67^{2}$ + $0.33^{2}$ + $0.17^{2}$

$\alpha ^{2}$ = 0.6956

$\alpha$ = 0.834

The standard deviation on the critical path = 0.834

Solve: 5.6 = 3.1 – 12.5|1 – 0.8x|

galben [10]

Answer:

<h3>There are no solutions.</h3>

Step-by-step explanation:

<u>Questions:</u>

Solve: 5.6= 3.1 – 12.5|1 – 0.8x|

<u>To find:</u>

The value of x.

<u>Solutions:</u><u>
</u>

5.6= 3.1 – 12.5|1 – 0.8x|

First, do switch sides.

$\Longrightarrow:\sf{3.1-12.5\left|1-0.8x\right|=5.6}$

<u>Multiply by 10 from both sides.</u>

$\Longrightarrow: \sf{3.1*10-12.5|1-0.8x|*10=5.6*10}$

<u>Solve.</u>

31-125|1-0.8x|=56

<u>Subtract by 31 from both sides.</u>

$\Longrightarrow: \sf{31-125\left|1-0.8x\right|-31=56-31}$

<u>Solve.</u>

$\Longrightarrow: \sf{-125\left|1-0.8x\right|=25}$

<u>Divide by -125 from both sides.</u>

<u>Solve.</u>

$\Longrightarrow: \sf{\dfrac{-125\left|1-0.8x\right|}{-125}=\dfrac{25}{-125}=\boxed{\sf{No\ solutions.}}}$

<u>Therefore, the correct answer is "D. There are no solutions."</u>

<u></u>

I hope this helps, let me know if you have any questions.
