Answer:
2.0
Step-by-step explanation:
Couldn't really understnd what you wrote but I'll assume it's the standard deviation of a fair, 7-sided die
The standard deviation is just the square root of the variance (which is just the second moment minus the first moment squared)
The first moment (AKA the average is..)
The second moment is..

Answer:
the height of the ball after 2 seconds is 132 feet
Maximum height of the ball is 147.016 feet
domain is t>=0
Step-by-step explanation:
The function that models this situation is
To find the height of the ball after 2 seconds, we plug in 2 for t
the height of the ball after 2 seconds is 132 feet
To find maximum height we find out vertex
We apply formula x=-b/2a
a=-16 , b= 95
now we plug in 2.969 and find out y
Maximum height of the ball is 147.016 feet
Domain is the set of 't' values for which function is defined
Time 't' cannot be negative so t is all positive real number
domain is t>=0
