Solve the problems. Use the graph for the standard deviation points In a fishing contest, the length of the fish caught ranged from 11.5 inches to 23 inches with a mean length of 16.40 inches and
standard deviation of 4.71 inches. Assume there was a normal distribution. What percent of the fish caught would have a length
greater than 21.11 inches, one standard deviation above the mean?
a) 13.6% b) 84.1% c) 0.2% d) 15.9 f) 2.1%

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

the answer

b. they are parallel and will never intersect.

ratio is 2 : 9

the answer is three

13.5 : 3
