Suppose that a random variable X is continuously uniform between the values of 4 and 12. Find the variance of the distribution of the sample mean of a random sample of size 37. Round your answer to four decimal places.

Find an equation (in term of x) of line through the points (-1,3) and (1,4)

What should be done to solve the equation? x+14=21 add 14 to both sides of the equation. subtract 14 from the left side of the equation. add 14 to the left side and subtract 14 from the right side of the equation. subtract 14 from both sides of the equation.

Write the summation to estimate the area under the curve y = 1 + x2 from x = -1 to x = 2 using 3 rectangles and right endpoints
