Answer:
70.83% entrants will have distances between 150 and 160.
Step-by-step explanation:
This question is incomplete without an attachment; here is the attachment enclosed with the answer.
From the graph attached,
Number of entrants having distances between 150 and 160 feet = 8 + 9 = 17
Number of entrants between 140 and 200 feet = 8 + 9 + 4 + 2 + 1 = 24
Percent of entrants having distance between 150 and 160 feet = 
= 
= 70.83%
Therefore, 70.83% entrants will have distances between 150 and 160.

Answer:
x=3, y =2
(3,2)
Step-by-step explanation:
y =2/3 x
y = -2/3 x +4
set them equal to each other y=y
2/3 x = -2/3 x + 4
add 2/3 x to each side
2/3 x+2/3x = -2/3x + 2/3 x + 4
4/3 x = 4
multiply by 3/4 on each side to clear the fraction
3/4 * 4/3 x = 3/4 * 4
x = 3
now we need to find y
y = 2/3 x
y = 2/3 * 3
y =2
