The answer to the math probability question you are presenting above would be .475 or (47.5%). The value of 3 years multiplied by 1000 would equal to 3000, thus the person will listen to music 3000 hours a year - which is two standard deviations than the mean. Following the empirical rule, the answer would be .475.
Answer:
15°
Step-by-step explanation:
x = angle
Complement and x sum to 90° so the complement angle = 90 - x
x = 4 ( 90 -x) - 285
x = 360 - 4x - 285
5x = 75
x = 15°
Answer: the answer would be 20
Step-by-step explanation: The answer 20 is from 1400 divided by 70 making 20, if you take 1400 and turn it into 14 then 70 into 7 then divide 14 by 7 you get 2 now just add a zero to your answer.
