Answer:
N=27 individuals
Step-by-step explanation:
Analysis of variance (ANOVA) is employed to assess the differences among group means in a sample.
The sum of squares refers to the cumulative square of variation, which is the dispersion between each individual value and the overall mean.
While conducting a multiple regression, we aim to understand the relationship between multiple independent or predictor variables and one dependent or outcome variable.

We also have this property
The model's degrees of freedom in this instance is determined by where k = 2 represents the number of variables.
For the error's degrees of freedom in this case, it is indicated by . Knowing k allows us to ascertain N.
The total degrees of freedom would be
This leads us to conclude that the correct answer is N=27 participants.
</passuming>Answer: y²z⁴ / x¹²
Explanation:
1) The expression to simplify:
2) Rule: power of a power:
3) Rule: product of powers with identical bases
4) Add up the exponents
5) Transfer the negative exponent to the denominator:
The exponent attached to x is 12, for y it is 2, and for z it is 4.
Answer with explanation:
Total number of children = x
Total chocolates shared = y
In total, the chocolates distributed to the children equals 5 times the number of children, or 5 x.
Chocolates received by adults equal 20.
Let the number of adults be z.
Expressing this situation as an equation:
y = 5 x + 20 z
⇒Number of adults = z
