Answer:
Step-by-step explanation:
Cost price = $n
Mark up price = selling price- cost price
= (20% × $n)
Selling price = $n + (20% × $n)
Sales tax = 5% × ($n + (20% × $n))
Total cost = selling price + sales tax
Total cost = $n + (20% × $n) + 5% × $n + (20% × $n)
= 1.2 × $n + 0.06 × $n
= 1.26 × $n.
I dont know if this is what you are looking for but i think this is the answer of the question you are looking for which is the general equation of a horizontal hyperbola:
<span>(x-h)²/a² - (y-k)²/b² = 1 </span>
<span>with </span>
<span>center (h,k)
</span>What you need to do is replace the data and do the calculations
The correlation based on the computation is 0.97.
<h3>How to compute the value?</h3>
It should be noted that the question is that we should simply calculate the correlation which is r.
The correlation will be:
= Σ(x y) / (Σ(x²) × Σ(y²)
= 9627/✓(1118 × 87982)
= 9627 ✓98363876
= 9627/9917.86
= 0.97

Answer:
Step-by-step explanation:
Given that f(x) is a polynomial function.
This implies that f(x) has x terms of positive integral degrees and also rational coefficients only.
Since an irrational root is given a root of f(x), we find that its conjugate also should be a root of f(x)
i.e. If 
is a root, then 
is also a root.
(Because this only when multiplied will make coefficients rational)
So the factors of f(x) should be atleast
There can be other factors also but this is compulsory
