Answer:
The maximum height that the ball will reach is 81 ft
Step-by-step explanation:
Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.
For an equation of the form
So
the t coordinate of the vertice is:
In this case the equation is:
So
Therefore
Finally the maximum height that the ball will reach is
Answer:
Confidence Interval is (21.76928571,23.43071429)
Step-by-step explanation:
The Formula we are going to use is:
±
Where:
μ is the mean of sample
σ is the standard deviation of population
n is the sample size
z is the distribution
In our case:
μ=$22.60,σ=$2.50
For 98% Confidence level, 1-α=98%
α=2%
α/2=1%=0.01
From Cumulative standardized Normal Distribution table
=2.326
P=23.430714 P=21.769286
Confidence Interval is (21.76928571,23.43071429)
