Let x be a discrete random variable that possesses a binomial distribution with n=5 and p=0.87. What are the mean and standard d

Nookie1986 [14]

Answer:

$Mean = 4.35$

$SD = 0.5655$

Step-by-step explanation:

Given

$n = 5$

$p = 0.87$

Solving (a): Mean

$Mean = np$

$Mean = 5 * 0.87$

$Mean = 4.35$

Solving (b): Standard Deviation (SD)

$SD = np(1 - p)$

$SD = 5 * 0.87(1 - 0.87)$

$SD = 5 * 0.87 * 0.13$

$SD = 0.5655$

An airplane is traveling due east with a velocity of 583 miles per hour. The wind blows at 75 miles per hour at an angle of S58°

ASHA 777 [7]

Answer:

D. 647.8 miles per hour; S86.5°E

Step-by-step explanation:

We assume the wind direction is supposed to be S58°E. Then the bearing of the plane measured clockwise from north is 90°, and the direction the wind is blowing toward has a bearing of 122°. The resultant speed and direction is the sum of the two vectors, which is easily found using a suitable calculator:

583∠90° + 75∠122° = 647.8∠93.5°

The bearing of 93.5° translates to the direction S86.5°E.

_____

An angle east of south is subtracted from 180° (south) to find the equivalent bearing.
