American alligators. multi-sensor data loggers were at- tached to free-ranging american alligators in a study conducted by y. watanabe for the article “behavior of american alligators mon- itored by multi-sensor data loggers” (aquatic biology, vol. 18, pp. 1–8). the mean duration for a sample of 68 dives was 338.0 sec- onds. assume the population standard deviation is 100 seconds. a. find a 95% confidence interval for the mean duration, μ, of an american-alligator dive. b. repeat part (a) at a 99% confidence level

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
