Answer:

P(D) = 0.3

Step-by-step explanation:

P(A) = 0.5

P(D|A) = 0.6

P(D) = P(A) * P(D|A)

P(D) = 0.5 * 0.6 = 0.3

Answer:

<h3>1863 m squared</h3>

Step-by-step explanation:

So, the goal here is to find the area of each block individually then add it all together. In other words, you're gonna look for a way to solve for the missing square in the total large rectangle. Keep in mind 23 + 23 + 23 = 69 (aka the length of the whole rectangle)

So:

12 x 23 = the missing square = 276

31 x 69 = rectangle with the square = 2139

Total area = 2139 - 276 = 1863

A shoreline observation post is located on a cliff such that the observer is 280 feet above sea level. The observer spots a ship
morpeh [17]

Answer:

Step-by-step explanation:

a) D/280 = tan(90 - 6)

   D = 280tan84 = 2,664 ft

b) D/280 = tan(90 - 16)

   D = 280tan74 = 976 ft

ship speed = (2664 - 976) / 43 = 39.2 ft/s
