Answer: To find the mean of the given observations. we just need to first find the sum of the given observations and the divide the calculate sum by the total number of observations.
So here:
Sum of of observations 
Number of observations = 15
Therefore, the mean 
Answer:
1 : 5 2 : 10 3 : 15 4 : 20 5 : 25
Step-by-step explanation:
Answer: its 1/144
Step-by-step explanation:
Answer : Option D
Step by step explanation :
There is a 50-50 chance of snowing in Hawaii.
Sequence: -4, 8, -16
rate of increase: -16/8 = -2
If you make A1 the first term in the sequence you must use (n-1) in the explicit formula. If you go backwards in the sequence to find A0 = 2 then you would use n.
The don't have A0 = 2 listed as an option so we use A1 = -4 and (n-1) terms.
An = -4(-2)^(n-1)
Solving for the 5th term A5, use n = 5
A5 = -4(-2)^(5-1)
A5 = -4(16)
A5 = -64
So the answer is B.
