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)
Answer:
Last moth I spent $45 on clothing.
Step-by-step explanation:
To solve this problem, we just need to find 150% of $30.

Hello from MrBillDoesMath!
Answer:
12 m n^2
Discussion:
3m * 4 * n * n = => 3* 4 = 12
12 m * n * n => as n*n = n^2
12 m n^2
Thank you,

Answer:
62°
Step-by-step explanation:
There should be 180° in a straight line.
63+55=118.
180-118=62
My deepest apologies if it is incorrect.
