A plane flies due south for 600 miles. It turns and flies 250 miles ,35 degrees east of south. How far is the plane from it’s origin. Step by step..Explanation. Please..

237 miles

Step-by-step explanation:

If the plane flies south then you would go north to go to it's original spot. 35 degrees of south is almost 50, if you add the east and south given points then you get 200 and because it is in miles you would divide 200 and get 30, about. Because the number it was divided by was un-equal you add a 7 marking and get 237!

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
