Answer:1st one is 3 -6 7
8
Step-by-step explanation:
Cosecant of C = hypotenuse/ opposite side
hypotenuse =√ (-8)² + (-6)² = √100 = 10
Cosecant of C = 10/ -8 = - 5/4
Correct option A
Answer: 0
Step-by-step explanation:
Given that :
Mean score on test = 5
Standard deviation on test = 2
Distribution = normal
The mean value when Converted to a z - distribution :
Zscore = (x - mean) / standard deviation.
Hence z score for the mean score will be :
X = mean score
Zscore = ( 5 - 5) / 2
Zscore = 0 / 2
Zscore = 0
Mean value when Converted to a z distribution will be 0
The ship therefore travels 8 nautical miles per hour. If the ship traveled for 1 hour, then it traveled 8 nautical miles. If the ship ... If the ship traveled for 18 hours, then it traveled 144 nautical miles.
