Answer: c) choosing a consonant from the set {b, c, d, e, f}
Step-by-step explanation:
Since all of the choice sets have 5 values each, a 0.8 chance = 80% = .
So find the set with 4 values that meet the criteria.
A: 5/5 = 1 = 100%
B: 1/5 = 0.2 = 20%
C: 4/5 = 0.8 = 80%
D: 0/5 = 0 = 0%
Answer:
The bearing needed to navigate from island B to island C is approximately 38.213º.
Step-by-step explanation:
The geometrical diagram representing the statement is introduced below as attachment, and from Trigonometry we determine that bearing needed to navigate from island B to C by the Cosine Law:
(1)
Where:
- The distance from A to C, measured in miles.
- The distance from A to B, measured in miles.
- The distance from B to C, measured in miles.
- Bearing from island B to island C, measured in sexagesimal degrees.
Then, we clear the bearing angle within the equation:
(2)
If we know that ,
,
, then the bearing from island B to island C:
The bearing needed to navigate from island B to island C is approximately 38.213º.
