Is the mean and mean deviation the same❓❔

Mathematics

No.
The mean is the quotient of the sum of a set of values and the number of these values.
The mean deviation is the mean of the absolute deviations of a set of values. And the absolute deviation is the absolute value of the difference of a value and its mean.

Symbolically:
Mean: \overline{x}=\dfrac{1}{n}\sum_{i=1}^nx_i
Mean deviation: MD=\dfrac{1}{n}\sum_{i=1}^n|x_i-\overline{x}|

PLS HELP HAS TO BE CORRECT

Answer:

○ 4⁵\4²

Step-by-step explanation:

1. According to the Quotient-to-Power Exponential Rule, whenever you divide terms with exponents and coefficients, you subtract the exponents:

4²\4⁵ = 4⁻³

3. According to the Negative Exponential Rule [Reverse], you bring the denominator to the numerator while ALTERING THE INTEGER SYMBOL FROM POSITIVE TO NEGATIVE:

b⁻ⁿ = 1\bⁿ

However, according to the Negative Exponential Rule, you bring the denominator to the numerator while ALTERING THE INTEGER SYMBOL FROM NEGATIVE TO POSITIVE:

bⁿ = 1\b⁻ⁿ

Anyway, this is what you get using this exponential:

1\4³ = 4⁻³

4. Back to what I said about the <em>Quotient-to-Power</em> Exponential Rule, you subtract the exponents, but in this case, doing that will give you 4³. This is the ONLY uniqueness, while the rest of them are 4⁻³.

I am joyous to assist you anytime.

The length of each side of a square is increased by 2 inches. If the perimeter is 20 inches, write an equation to show the origi
Archy [21]
The new length side of the perimeter, we'll call p. The original length, we'll call o. P's equation looks like this:
p = 20 \times  \frac{1}{4}
Since 5 is the length of one side, subtract 2 from 5 to get 3. The equation looks like this:
o =  \frac{20}{4}  - 2
or simply
o = 5 - 2
