Answer:
a) 54 m is your answer
Step-by-step explanation:
Given: s = 9
The formula given is:
P (Perimeter) = 6s
Plug in 9 for s
P = 6(9)
Multiply.
P = 6(9)
P = 54
a) 54 m is your answer

The sets for each of the given numbers are:
- 6426: Real, rational, integer and whole.
- √7: Real and irrational.
- 2π: Real and irrational.
- 4.0: Real, rational, integer, whole.
- √(25/36): Real and rational.
- -√16: Real, rational, and integer.
- -35: Real, rational, and integer.
- -31.8: Real and rational.
<h3>
To which set each number belong?</h3>
Here we need to identify 3 sets
- Rational numbers: all of these that can be written as a quotient of two integers.
- Irrational numbers: all of these that can't be written as a quotient of two integers.
- Integers: Any number that can be got by adding or subtracting ones.
- Whole numbers: All the integers equal or larger than 0.
- Real number: any of the above is a real number.
The first number is:
6426
It can be rewriten to:
6426/1
So this is: Real, rational, integer, and whole number.
Second number:
√7
This is a real and irrational number (square roots of non-square numbers are irrational numbers).
Third number:
2π
This is a real and irrational number, because π is irrational.
Fourth number:
4.0
This is: Real, rational, whole, and integer.
Fifth number:
√(25/36)
We can simplify that to:
√(25/36) = 5/6
So this is a real and rational number.
Sixth number:
-√16 = -4
That is a: Real, rational, and integer number
Seventh number:
-35
Same as the above one, real, rational, and integer.
Eight number:
-31.8
It can be written as:
-31.8 = -318/10
So this is real and rational number.

Answer:
The answer is "25 in"
Step-by-step explanation:
Please find the complete question in the attached file:
Given:
Using the Pythagorean theorem:
A line of best fit is a line drawn at average distance to a series of scattered points. Thus, the correct option is:
Option B. The <em>data</em> point is 4. 5 units <u>below</u> the line of best fit.
A graph is said to be formed by plotted points on a <u>Cartesian </u>coordinate plane. When the plotted <em>points</em> are <u>scattered</u>, a <em>line of best fit</em> is required to shoe the relationship among the plotted <em>points</em>.
A <u>residual</u> <u>value</u> is a form of error that is determined from the <em>line of best fit</em>. A <u>line of best fit</u> is a line drawn at <em>average</em> point to a <em>series</em> of plotted <em>scattered</em> points.
Therefore, a residual value of 4.5 with respect to a <em>line of best fit</em> implies that: The data point is 4. 5 units <u>below</u> the <em>line of best fit</em>.
Thus the <em>correct</em> option is B.
