That answer would be 1.5 just divide 6/4
Answer:
The resultant velocity of the airplane is 213.41 m/s.
Step-by-step explanation:
Given that,
Velocity of an airplane in east direction, ![v_1=210\ mph](https://tex.z-dn.net/?f=v_1%3D210%5C%20mph)
Velocity of wind from the north, ![v_2=38\ mph](https://tex.z-dn.net/?f=v_2%3D38%5C%20mph)
Let east lies in the direction of the positive x-axis and north in the direction of the positive y-axis.
We need to find the resultant velocity of the airplane. Let v is the resultant velocity. It can be calculated as :
![v=\sqrt{v_1^2+v_2^2}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7Bv_1%5E2%2Bv_2%5E2%7D)
![v=\sqrt{(210)^2+(38)^2}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%28210%29%5E2%2B%2838%29%5E2%7D)
v = 213.41 m/s
So, the resultant velocity of the airplane is 213.41 m/s. Hence, this is the required solution.
Answer:
0.2416
Step-by-step explanation:
P(forgot to water | dead) = P(forgot and dead) / P(dead)
->With water it will die with probability 0.45
P(watered and dead) =0.83 x 0.45 = 0.3735
->Without water the plant will die with probability 0.7
P(forgot and dead) = (1-0.83) x 0.7 => 0.17 x 0.7 =>0.119
P(dead) = P(watered and dead) +P(forgot and dead)
P(dead) = 0.3735 + 0.119= 0.4925
P(forgot to water | dead) =0.119 / 0.4925= 0.2416
Therefore, the probability the neighbor forgot to water the plant is 0.2416
I think 2 equal ratios are called a <u>proportion</u>
