7.) By clusterring $7.04 + $5.95 + $6.08 + $5.06 + $6.12 = $6.00 + $6.00 + $6.00 + $6.00 + $6.00 = $30.00
8.) 9.3 + 8.7 + 8.91 + 9.052 = 9 + 9 + 9 + 9 = 36
9.) 37.6 + 44.1 + 41 + 39.1 = 40 + 40 + 40 + 40 = 160
In clustering method you look for a whole number usually ending with 0 which all the given numbers "clustered" around.
M=ch x 4 next 3 = mch (34)
N + 2 = 13
-2 -2
n = 11
I hope this helps!
Answer: 6
Step-by-step explanation:
Given Data:
Number of people = 6
Amount of Gold to be shared = 40lbs
Subtract 2/3 from your answer.
Therefore
If six people are to share 40lbs of gold evenly
= 40lbs / 6
Divide through by 2
= 20lbs / 3
= 20lbs / 3 - 2/3
= 18/3
= 6
Each person would get approximately 6lbs of gold
The expression that is not a variation of the Pythagorean identity is the third option.
<h3>
What is the Pythagorean identity?</h3>
The Pythagorean identity can be written as:

For example, if we subtract cos^2(x) on both sides we get the second option:

Which is a variation.
Now, let's divide both sides by cos^2(x).

Notice that the third expression in the options looks like this one, but the one on the right side is positive. The above expression is in did a variation of the Pythagorean identity, then the one written in the options (with the 1 instead of the -1) is incorrect, meaning that it is not a variation of the Pythagorean identity.
Concluding, the correct option is the third one.
