<span>The kinetic energy is 6395.03 J</span>
Mean : m = 2.2
Standard deviation: s = 0.3
m - 1 s = 2.2 - 0.3 = 1.9
m + 1 s = 2.2 + 0.3 = 2.5
For the normal distribution the values less than 1 standard deviation away from the mean account for 68.27 % of the set.
Answer: D ) 68 %
Answer:
B
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
