Answer:
The sequence above is a geometric sequence
For an nth in a geometric sequence
where n is the number of terms
a is the first term
r is the common ratio
From the question
a = 45
r = 15 / 45
The explicit formula for the sequence is
U(n) = 45(1/3)^n-1

The estimate closest to an average person's weight is 80kg
<h3>How to determine the estimate?</h3>
The weights are given as:
8 kg, 80 kg and 800 kg
To answer this question, I will assume that a person means an adult
An adult that weighs 8 kg is very much under weight
Because the average weight of a person is around 60 to 90 kg
Hence, the estimate closest to an average person's weight is 80kg

Step-by-step explanation:
y2 + 4y - 5
( y + 4 )( y - 1 )
so you just need to break down the sum
Answer:
The right answer is "0.33".
Step-by-step explanation:
As per the question,
n = 15
Average will be "x = 5"
Now,
The required proportion will be:
⇒ 
By putting the values, we get
⇒ 
⇒ 
Thus, the above is the appropriate solution.
