The measure of an inscribed angle is x, and the measure of its intercepted arc is y. Which equation describes the relationship between x and y?

Determine the area of a triangle with (see picture below)

Arandom sample of n = 25 observations is taken from a n(µ, σ ) population. a 95% confidence interval for µ was calculated to be (42.16, 57.84). the researcher feels that this interval is too wide. you want to reduce the interval to a width at most 12 units. a) for a confidence level of 95%, calculate the smallest sample size needed. b) for a sample size fixed at n = 25, calculate the largest confidence level 100(1 − α)% needed.

Ndicate in standard form the equation of the line through the given points. p(0, -4), q(5, 1)
