Given: △ABC m∠A=60°, m∠C=45° AB=12 Find: The perimeter.

Answer: 0.5507

Step-by-step explanation:

Given: The time between sightings of speeders by a radar system is represented by the continuous random variable X, which follows a cumulative distribution function

If we convert 12 minutes into hours, it equals hours or 0.2 hours.

To find the probability of waiting less than 12 minutes:

Thus, the probability we are looking for is: 0.5507

8 out of 300 were defective.



That corresponds to 80 pairs being defective

X² + 7x - 8 = 0; product = -8 times 1 = -8; sum = 7; {-1, 8}; x² - 1x + 8x - 8 = 0; x(x - 1) + 8(x - 1) = 0; thus, x + 8 = 0 or x - 1 = 0, leading to x = -8.
