Slope
And
These are acceleration
Y intercept is (0,2) as x coordinate is 0
This is initial velocity 2m/s
The runner stopped at 8s
Answer:
60 m
Step-by-step explanation:
A^2+b^2=c^2
a^2+45^2=75^2
a^2+2025=5625
a^2=3600
a=60
Answer:
The standard deviation of the sample is 0.0064.
Step-by-step explanation:
The standard deviation of a sample of length n of a population with standard deviation is given by the following formula:
In this problem, we have that:
61 randomly selected gas stations. This means that
The standard error of the mean is $0.05. This means that .
What is the standard deviation of the sample?
The standard deviation of the sample is 0.0064.
Mid point b/w (18,-6),(0,0)
X = 0+18/2 = 9
y = 0-6/2 = -3
thus mid point is (9,-3)
