If there is 10% of $18 = 18 x 0.9 (1 - 0.1) = $16.20
Therefore the pie costs $16.20
He is saving 18 - 16.20 = $1.80
The roots routine will return a column vector containing the roots of a polynomial. The general syntax is
z = roots(p)
where p is a vector containing the coefficients of the polynomial ordered in descending powers.
Given a vector
which describes a polynomial
we construct the companion matrix (which has a characteristic polynomial matching the polynomial described by p), and then find the eigenvalues of it (which are the roots of its characteristic polynomial)
Example
Here is an example of finding the roots to the polynomial
--> roots([1 -6 -72 -27])
ans =
12.1229
-5.7345
-0.3884
A. $330 for the 3 day trip if she does not go over 400 km
b $315 for the cost of the Unlimited Mileage plan.
c. the Unlimited Mileage plan would save you $15 compared to the Standard Daily Rate.
Hello :
An = A1×q^(n-1)....A1 =1 and q = 1.5
An = 1×(1.5)^(n-1)
An =(1.5)^(n-1)
<span> the 9th term is A9 =(1.5)^8</span>
Class 1 has more variability because both the range and interquartile range are greater than class 2, meaning the data is more spread out.
<h3>What is range and interquartile range?</h3>
The range is the difference between the largest number and the smallest number in a dataset. The interquartile range is the difference between the first quartile and the third quartile of a dataset.
Range and interquartile range are used to measure the spread of a dataset. The higher range and interquartile range is, the greater the spread and variability of the dataset.
