<span>Given a mean = 1300 and a Ď = 200, we can calculate that the lower bound of 1000 is (1000 - 1300) / 200 = -1.5 standard deviations below the mean.
The upper bound is (1437 - 1300) / 200 = 0.685 standard deviations from the mean.
Using the cumulative distribution function, we can calculate that the probability a randomly chosen steer lies on the interval [1000, 1437] is CDF(0.685) - CDF(-1.5) = 0.68652083824480004

1. 1x-11. 6x+9 + 5x-20 = 1x-11
2. -2x-11. X-8 -3x-3 = -2x-11
Answer:
<h2>5 m</h2><h2 />
Step-by-step explanation:
area = L x W
41 = L ( 8.2)
L = 41 / 8.2
L = 5 m
