please help! Chapter 6, Section 2-CI, Exercise 086 Use the t-distribution to find a confidence interval for a mean y given the relevant sample results. Give the best point estimate for y, the margin of error, and the confidence interval. Assume the results come from random sample from a population that is approximately normally distributed. A 99% confidence interval for u using the sample results I = 85.9, s = 30.0, and n = 15 Round your answer for the...

(1 point) The region W lies below the surface f(x,y) = 7e-(æ=3)*"-y* and above the disk x2+y2 < 36 in the xy-plane. (a) Think about what the contours of f look like. You may want to using f(x,y) = 1 as an example. Sketch a rough contour diagram on a separate sheet of paper. (b) Write an integral giving the area of the cross-section of W in the plane = 3. d Area = and b where a= (c) Use...
Let f(x,y)=x2y2+1.f(x,y)=x2y2+1. Use the Linear Approximation at an appropriate point (a,b)(a,b) to estimate f(5.02,1.91).f(5.02,1.91). (Use decimal notation. Give your answer to two decimal places.) f(5.02,1.91)≈ Let f(x, y) = . Use the Linear Approximation at an appropriate point (a, b) to estimate f(5.02, 1.91). (Use decimal notation. Give your answer to two decimal places.) f(5.02, 1.91) - 4.59
