Answer:
mean = 250.2
mean = 249.4
Step-by-step explanation:
given data
experiment = 15 times
solution
we get here mean that is express as
mean = 
............1
so mean for cart 1 is
mean = 
mean = 250.2
and
mean for cart 2
mean = 
mean = 249.4
Since it’s perpendicular tu have to flip the slope and change the sing which in this case would be -1/5
Then you put the equation together:
y-7=-1/5(x-5)
Distribute:
y-7=-1/5x+1
Add the 7 to both sides of the equation:
y-7=-1/5x+1
+7 +7
And the final answer is: y=-1/5+8
200, 100, 200, and 100. if you mean HUNDRETH then they are all already to the nearest hundredth
BC is 21 meters.
2x + 5 + 3x = 45
5x + 5 = 45
5x = 40
X = 8
2(8) + 5 = BC
21 = BC
