Answer:

Probability will be 0.3428

Explanation:

Because probability is the preferred over total, we want the number of delegations with 2 CPA's over the number of total delegations.

We have 9 CPA's and we need to choose 2, thus the number of delegations with 2 CPA's ^9C_2=\frac{9!}{2!7!}=36

To find the total number of delegations, we have 15 accountants and we need to choose 2, thus, ^12C_2=\frac{12!}{2!10!}=105

Thus our probability will be  =\frac{36}{105}=0.3428

enyata [817]

Answer:

b. feel and act "different" from childhood on.                            

Explanation:

Nurture plays an important role in the development of a child. The environment in which a child is being placed tends to determine the nature and habit of the child. Also, a child develops a great part of hir or her personality in childhood only.

Since, the child who was born as a biological female and was raised as a male tends to behave like a boy because the girl is being given a male name, dressed up as a male etc. These things will have a great impact on the girl's life as the people around the child will treat her that way.

How do you derive the simplified version for each component in the simple vapor-compression cycle?
vfiekz [6]

The compressor, condenser, expansion valve/throttle valve, and evaporator are the four elements that make up the vapor compression cycle.

The main difficulties in vapor compression refrigeration system miniaturization for designs based on standard-scale systems have to do with component integration and miniaturization.

The most important aspect of all mechanical refrigeration systems is the creation of a compact yet effective gas compressor.

The first factor is connected to the most basic separation mechanism that comes to mind: gravity. The maximum vapor velocity that is permitted should be determined by looking at the terminal velocity of the droplets if gravity settling is to be employed as a separation technique. This will prevent the droplets from being swept away with the vapor.

To learn more about velocity refer to:
