ten athletes ran two races of the same length. The scatter plot shows their times. Select all statements that are true.
2 answers:
The scatter plot has been attached
Answer:
Options C, D & E are true
Step-by-step explanation:
Option A is wrong because from the scatter plot, only four athletes were faster in the second race than in the first one.
Option B is wrong because only 1 athlete had his second race time differing from the first race time by exactly 2 seconds.
Option C is true because exactly 9 of the times for the first race were at least 16 seconds
Option D is true because there are exactly 3 athletes who had the same time in both races
Option E is true because 8 of the times for the second race were less than 17 seconds

Answer:
Coordinates of point B are (10,-4)
Coordinates of point D are (3.6,-0.4)
Step-by-step explanation:
1) Point C(3.6, -0.4) divides in the ratio 3 : 2. If the coordinates of A are (-6, 5), the coordinates of point B are ____
Let the coordinates of B be
Coordinates of A =
Coordinates of C=(x,y)=(3.6,-0.4)
We will use section formula over here
m:n=3:2
Coordinates of B = (10,-4)
2)If point D divides in the ratio 4 : 5, the coordinates of point D are ____
(fraction)
Let the coordinates of D be
Coordinates of A =
Coordinates of B=
We will use section formula over here
m:n=3:2
Coordinates of point B are (10,-4)
Coordinates of point D are (3.6,-0.4)
