,12x12=144.................
Let's take a look at the first few numbers in the sequence based on the given rule:

Inspecting this pattern it seems like the power

is being raised to is always one less than the number of the sequence, so if we were on the nth number in the sequence, that part of the expression would be

. We also know that we'll be multiplying whatever we get from that by 6, so we can write the full explicit rule for our sequence as

Where

is the nth number in our sequence.
A is the answer because x^2-6x-7 is (x-7)(x+1).
Correct Answer:
C option: 6 feetSolution:Since <span>Yolanda wants to keep the pool in proportion to the model, the ratio of diameter to depth of model and the pool will be same.
Let the depth of pool is x feet. So we can write:
Ratio of Diameter to Depth of Model = Ratio of Diameter to Depth of pool
</span>

<span>
This means the depth of pool should be 6 feet if </span><span>Yolanda wants to keep the pool in proportion to the model.</span>
The coding of the statistic is used to make it easier to work with the large sunshine data set
- The mean of the sunshine is 3.05

- The standard deviation is approximately <u>18.184</u>
<u />
Reason:
The given parameters are;
The sample size, n = 3.
∑x = 947
Sample corrected sum of squares, Sₓₓ = 33,065.37
The mean and standard deviation = Required
Solution:

The mean of the daily total sunshine is therefore;



- The mean ≈ 3.05

Alternatively
,
The mean of the daily total sunshine,
≈3.05

Therefore;

Therefore;
The standard deviation,
≈ <u>18.184</u>
