Answer:
Step-by-step explanation:
Let us first generate the frequency table from the information given:
Hurricane number(X) Frequency(f) f(X)
6 9 54
8 13 104
12 16 192
14 12 168
Total ∑(f) = 50 ∑f(x) =518
In order to determine the last frequency (the remaining years), we will add the other frequencies and subtract the answer from 50, which is the total frequency (50 years). This is done as follows:
Let the last frequency be f
9 + 3 + 16 + f = 50
38 + f = 50
f = 50 - 38 = 12
Now, calculating mean:

Therefore mean number of hurricanes = 10.4 (to one decimal place)

Step-by-step explanation:
In a parallelogram
• opposite sides are congruent
• the diagonals bisect each other
Then
UT = 27 ( congruent to RS )
ST = 18 ( congruent to RU )
VS = 7 ( congruent to UV )
VT = 15 ( half of RT )
