Let p3 have the inner product as in exercise 9, with p0, p1, and q the polynomials described there. find the best approximation to by polynomials in span . reference: let p3 have the inner product given by evaluation at

a) compute the orthogonal projection of p2 onto the subspace spanned by p0 and p1.
b) find a polynomial q that is orthogonal to p0 and p1, such that is an orthogonal basis for span scale the polynomial q so that its vector of values at .

no te preocupes por eso

Step-by-step explanation:

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
