Two planes, a and b, start from the same place and move in different directions, making an angle of 50° between them. the speed of plane a is
200 miles per hour, and the speed of plane b is 300 miles per hour.
the two planes are
miles apart after one hour.

The two planes are 230 miles away after one hour.

Step-by-step explanation:

We know the speed of airplanes A and B and we know the angle between the speeds of both.

If the speed of plane A is 200 miles per hour, and the speed of plane B is 300 miles per hour, then after 1 hour the plane A will have traveled 200 miles and the plane B will have traveled 300 miles.

If we call c the distance between the two planes then we can use a triangle of sides, a, b and c

Where

c = distance between both planes

Side c is opposite the angle of 50 °.

Then we use the law of cosine to find c.

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
