Find the area enclosed by the x-axis and the curve x = 4 + et, y = t − t2.

Find where the curve intersects the x-axis; this happens when y = 0:

y = t - t ² = 0   →   t (1 - t ) = 0   →   t = 0, t = 1

Then the area of the bounded region is

(you can compute the integral by parts)

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

step-by-step explanation:

their are no angles. sorry cant .
