Aplane directly above denver, colorado, (altitude 1650 meters) flies to bismark, north dakota (altitude 550 meters). it travels at 700 km/hour at a constant height of 8250 meters above the line joining denver and bismark. bismark is about 850 km in the direction 60∘ north of east from denver. find parametric equations describing the plane's motion. assume the origin is at sea level beneath denver, that the x-axis points east and the y-axis points north, and that the earth is flat. measure distances in kilometers and time in hours.

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

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
