Find k so that the following function is continuous on any interval: f(x)= kx 0 (less than or equal to) x (less than) 2 3x^2 2 (less than or equal to x) i know the answer is 12 but i don't know how to arrive at that
In the following exercises, find the value(s) of k that makes each function continuous over the given interval. 145. f(x) = $3x + 2, x<k 12x – 3, k < x < 8 3 153. Apply the IVT to determine whether 2* = x has a solution in one of the intervals [1.25, 1.375] or [1.375, 1.5]. Briefly explain your response for each interval. Determine whether each of the given statements is true. Justify your response with explanation or counterexample....

Consider the function f(x)=2x^3−3x^2−72x+6 on the interval [−5,7]. Find the average or mean slope of the function on this interval. Average slope: 0 By the Mean Value Theorem, we know there exists at least one value cc in the open interval (−5,7) such that f′(c) is equal to this mean slope. List all values cc that work. If there are none, enter none . Values of c:
Find the absolute extreme values of the function on the interval. -x^2+7x-10, 2 less than or equal to x less than or equal to 5
Suppose that X has a probability function f(x) = cx(x-1) 0 equal to or greater than x less than or equal to 1 other wise 0 find Var(X)? I know C value is 6
Please show all steps, formulas or any visuals necessary so that I may better understand how to approach other similar problems because I don't know how to get started, thank you. Recall that If X is a continuous random variable with density f(x)= , 0, Otherwise find EX.
Problem(2) (5 points) A continuous distribution has density function k sin(r); 0rST 0; f(x) = otherwise. (a) Find the numerical value of k so that f(r) is a density function.

in part A. We are going to find the value of Okay, so we know that the integral awful. The pdf, It should be one and in this case the integral is from 0 to 1. This is okay X cubed dx. So it is K over four X to the fourth. 0 1 plug in and subtract. So we get que over for here. So this implies that K equal four in part B. We are going to compute...
Consider a value to be significantly low if it's z score less than or equal to -2 or consider a value to be significantally high if it's z score is greater than or equal to 2. A test is used to assess readiness for college. In recent year, the mean test score was 22.8 and the standard deviation was 5.3. Identify the test scores that are significantly low or significantly high. What test scores are significantly low? What test scores are significantly high? (Please...
