Answer:
Steven is faster than Michelle by covering 0.64 meters more per second than that of Michelle.
Step-by-step explanation:
Given:
Steven swam 200 m in 25.7 seconds while Michelle finished in 28 seconds.
So, speed of Steven is,
Speed of Michelle is,
Now, to find how much faster did Steven swim than Michelle, we need to get the difference between their speeds.
Speed of Steven - Speed of Michelle
So, Steven is faster than Michelle by covering 0.64 meters more per second than that of Michelle.
To find the midpoint of a segment you need to use this equation:
(x1+x2/2, y1+y2/2) so if you plug in the numbers its...
9+(-7)/2, 2+(-9)/2
then solve to find x and y coordinate
x= 1 and y= -3.5
so the midpoint of CD is (1,-3.5)
It is both, as you subtract 550 from 0, and then you subtract another 270, but then add 400. You subtract 2 numbers then add 1.
To find out the median number, you'd have to arrange the numbers in order first.
4,5,8,9,10
Then you'll have to find out the number in the middle, which is 8.
Hope that helps.
