Answer:
Step-by-step explanation:
acceleration, a = 20 m/s^2
initial velocity, u = 0 since it starts from rest
final velocity, v = 400 m/s
v = u + at
400 = 0 + 20 t
400 = 20 t
t = 400 / 20
<u><em>t = 20 sec</em></u>

1,725 yards, because 575×3=1,725. Or 575+575+575=1,725
First, find the mean. You'll need it to compute the variance.

The variance of the sample is then computed with the formula

The standard deviation is the square root of the variance, so
Answer:

Step-by-step explanation:
We need to find which statements are true.
Solution to find the same we will solve each statement and will conclude the same.
1. 
Now On solving we get;


So we can see that 0.70 > 0.66
Hence The given statement is False.
2. 
Now On solving we get;


So we can see that 0.5625 > 0.5
Hence The given statement is True.
3. 
Now On solving we get;


So we can see that 1.33 > 1.2
Hence The given statement is False.
4. 
Now On solving we get;


So we can see that 0.82 > 0.66
Hence The given statement is False.
