For questions 3 – 5, an airplane is heading south at an airspeed of 540 km/hr, but there is a wind blowing from the northeast at 50 km/hr.What is the plane’s bearing with the wind?Select one:a.94⁰b.274⁰c.184⁰d.176⁰
1 answer:
First, let's calculate the horizontal and vertical components of the wind speed (W) and the airplane speed (A), knowing that south is a bearing of 270° and northeast is a bearing of 45°:
Now, let's add the components of the same direction:
To find the resultant bearing (theta), we can use the formula below:
The angle -86° is equivalent to -86 + 360 = 274°.
Therefore the correct option is b.

Answer:
Step-by-step explanation:
To see if two events are independent you can use the formula P(a|b) = P(a)
In this problem P(C|Y) = 35/75 = .4667 and P(C) = 110/300 = 3.667,
therefore C and Y are not independent events because P(C∣Y) ≠ P(C).
The answer is choice D
Answer:
The initial cost of the cell phone was $364
Step-by-step explanation:
Since there was a 30% markup, 70% of the new cost is the initial cost. Multiply 520 by 0.7 on a calculator and you get 364
