Test the set of polynomials for linear independence. If it is linearly dependent, express one of the polynomials as a linear combination of the others. (If the set is linearly independent, enter INDEPENDENT. If the set is linearly dependent, enter your answer as an equation using the variables f, g, h, and j as they relate to the question.) {f(x) = 1 − 7x, g(x) = 9x + x2 − x3, h(x) = 1 + x2 + 7x3, j(x) =...

Consider the following functions. f1(x) = cos(2x), f2(x) = 1, f3(x) = cos2(x) g(x) = c1f1(x) + c2f2(x) + c3f3(x) Solve for c1, c2, and c3 so that g(x) = 0 on the interval (−∞, ∞). If a nontrivial solution exists, state it. (If only the trivial solution exists, enter the trivial solution {0, 0, 0}.) {c1, c2, c3} =? Determine whether f1, f2, f3 are linearly independent on the interval (−∞, ∞). linearly dependent or linearly independent?

Let U and V be vector spaces, and let L(V,U) be the set of all linear transformations from V to U. Let T_1 and T_2 be in L(V,U),v be in V, and x a real number. Define vector addition in L(V,U) by (T_1+T_2)(v)=T_1(v)+T_2(v) , and define scalar multiplication of linear maps as (xT)(v)=xT(v). Show that under these operations, L(V,U) is a vector space.

Using built in R functions to calculate mean and standard deviation. Simulate the X vector with a length of 50 from a normal distribution with mean 2 and variance 1. Using a for() loop, create 100 different confidence intervals and also create a variable that keeps a count of how many of these confidence intervals contain the true mean 2. Hint: Use If/else statement to keep track of whether the confidence interval contains the true mean or not within the...
