Using probability concepts, it is found that:
a) The missing value is 0.04.
b) The mean is of 0.37.
The distribution is given by:
Item a:
The sum of <u>all the probabilities has to be 1</u>, that is:
Thus:
The missing value is 0.04.
Item b:
The mean is given by the <u>sum of each outcome multiplied by it's probability</u>, thus:
The mean is of 0.37.

Answer:
The polygons are similar.
Step-by-step explanation:
By definition, the corresponding sides and angles of similar polygons must be in some constant proportion.
Therefore, we can find the ratio between corresponding sides to see if that ratio is maintained.
The side marked 3 cm in the smaller figure corresponds with the side marked 3.75 cm in the larger figure. This proportion is .
The side marked 5 in the smaller figure corresponds with the side marked 6.25 cm in the larger figure. This proportion is .
If these polygons are similar, these proportions must be equal.
Checking, we see that these proportions are equal, and therefore the polygons are similar.
