The answer is the option 3. (the arrow aimed to the center of the polygon)
Why?. Because the particle changed the direction of its movement due to a force inclined respect the motion and aimed to the center. Take in account that the vectors net force and acceleration are parallel.
Part a)
The mean height is 69 inches with a standard deviation of 2.5 inches.
If we consider a interval of heights that relies on no more than two standard deviations from the mean, we will cover, approximatelly, 95% of men's heights. Then, we interval that we're looking for is:
Answer: 64 TO 74 INCHES
Part b)
Since [69,74] is half of the interval in the previous answer, we might expect half of 95% as the percentage of men who are in this interval. That is:
Answer: 47.5 PERCENT
Part c)
A interval of heights that relies on no more than one standard deviation from the mean covers, approximatelly, 68% of men's heights. Then, we can consider that the percentage of men that are between 64 and 66.5 inches is given by 47.5 - 68/2 = 13.5.
Answr: 13.5 PERCENT

Answer:
36. m^7
37. x^3 y
38. 6v^5
Step-by-step explanation:
Divide the exponents by the number in the radical sign,
so, If no number is given then divide exponents by 2 eg. question 38
<h3>Explanation </h3>
36. 7√m^49 means m^(49/7) = m^7
37. 3√x^9y^3 means x^(9/3) y^(3/3) = x^3 y
38. √36v^10 means (√36) v^(10/2) = 6v^5 (√36 = 6)
7/25 = 28/25 = 28%18/25 = 72/100 = 72%
28 percent was blue and 72 percent was red
