Retries
the Following Table Contains the Probability Distribution for X

question 30

True/False

Retries
The following table contains the probability distribution for X = the number of retries necessary to successfully transmit a 1024K data package through a double satellite media.
$$\begin{array} { | c | c c c c | } \hline \boldsymbol { x } & 0 & 1 & 2 & 3 \\\hline \boldsymbol { p } ( \boldsymbol { x } ) & 0.35 & 0.35 & 0.25 & 0.05 \\\hline\end{array}$$
-If X and Y are two variables with $$\sigma _ { x } ^ { 2 } = 12.25$$ , $\sigma _ { y } ^ { 2 } = 17.64$ ,and COV(X,Y)= 11.76,then the coefficient of correlation $\sigma$ = 0.8.

Definitions:

Continental Shelves

Submerged landforms at the edges of continents, extending from the coastline to a sharp drop-off into the deeper ocean floor.

Shallow Seawater

Areas of the ocean that are not deep, often found near coastlines, characterized by relatively low depths.

Sea Mounts

Undersea mountains formed by volcanic activity, rising from the ocean floor but not reaching the surface.

Island Arcs

Curved chains of volcanic islands located along convergent tectonic plate boundaries, typically with deep ocean trenches on the convex side.
