Answer:
Explicit formula: 
Step-by-step explanation:
Let the number of squares in 
layer be 
Given:
Number of squares in first layer, 
Number of squares in second layer, 
Therefore, the number of squares increases by a factor of 2.
So, it follows a geometric sequence with the first term as 6 and common ratio of 2.
For a geometric sequence, the term with common ratio 
is given as:
Here, 
∴ Explicit formula:
Answer:y=42

Answer:
A) Average weight = 112.97
standard deviation = 3.913
B) 119.4069
Step-by-step explanation:
A) Estimate the true average weight and standard deviation of the weight
attached below is a detailed solution
Average weight = 112.97
standard deviation = 3.913
B) Assuming a normal distribution Estimate the weight below
attached below is a detailed solution
= 119.4069
Since the 50 remains the same every time, is has no letters next to it in the equation. The 20, however, is multiplied by the amount of hours, and will therefore have an h next to.
20h + 50- the answer is a.
