You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures: 57.9
25.4
19.8
28.3
60.7
39.4
51.1
63.4

Find the 99% confidence interval. Enter your answer as an open-interval (i. e., parentheses) accurate to two decimal places (because the sample data are reported accurate to one decimal place).

(If you could please show step by step, that would be very helpful!)

What is the slope of the equation y =

Circle d circumscribes abc and abe. which statements about the triangles are true? statement i: the perpendicular bisectors of abc intersect at the same point as those of abe. statement ii: the distance from c to d is the same as the distance from d to e. statement iii: bisects cde. statement iv: the angle bisectors of abc intersect at the same point as those of abe. a. i only b. i and ii c. ii and iv d. i and iii e. iii and iv

Using the rise/run counting method, the slope of the line is
