From the airport hanger H, an areoplane A is 18km away on the bearing of 115° while another aeroplane B is 29km away on a bearin
maks197457 [2]

The difference in distance between Aero plane A and B is; 34.67 km

<h3>How to calculate bearing?</h3>

To get the bearing;

∠H = (115 - 90) + (270 - 203)

∠H = 92°

Then, we will use cosine rule to get the distance between both Planes A and B.

d_ab = √(18² + 29² - 2(18 * 29) * cos 92)

d_ab = √(324 + 841 + 36.435)

d_ab = 34.67 km

A film distribution manager calculates that 9%9% of the films released are flops. If the manager is right, what is the probabili
alexdok [17]

Answer:

The probability that the proportion of flops in a sample of 442 released films would differ from the population proportion by greater than 4% is:

= 0.094

= 9.4%

Step-by-step Explanation:

Estimated probability that the films released are flops = 9%

Sample of released films = 442

Estimated number of flops = 39.78 (442 * 9%)

If the population proportion of flops will be greater by 4%,

Therefore, the number of flops will increase to 41.37 (39.78 * 1.04)

This gives a new proportion of flops as 0.0936 (41.37/442)
