The triangles are similar. What is the value of x.

Zarrin [17]

Answer:

The answer to your question is x = 6

Step-by-step explanation:

To solve this problem use proportions. Just look for the right sides so the proportion be correct.

Sides of the small triangle = Sides of the big triangle

$\frac{x}{4} = \frac{12}{8}$

Solve for x

$x = \frac{4(12)}{8}$

Simplification

x = $\frac{48}{8}$

Result

x = 6

There are four activities on the critical path. Coincidentally, their standard deviations are all equal to 4. The standard devia

hichkok12 [17]

Answer:

the standard deviation of the critical path is 8

Step-by-step explanation:

The computation of the standard deviation of the critical path is shown below:

As we know that

Variance = Standard deviation^2

Now the variance of the critical path is

= Variance 1 + variance 2 + variance 3 + variance 4

= 4^2 + 4^2 + 4^2 + 4^2

= 64

Now the standard deviation would be

= √64

= 8

hence, the standard deviation of the critical path is 8
