The expression for the kinetic energy is mass times velocity squared over two
For the first question that gives us 2,25 joules
If the ball is at the given height then it has a further 60 Joules in potential energy.

Step-by-step explanation:
Answer:
m<OPQ + (x+16)° + (6x - 4)° = 360°

Answer:
e. We are 99% confident that the difference in the population percents of all men and women who are fans of a professional football team is between 13.3% and 20.7%.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
99% confidence interval for the difference in the proportion of fans of a professional football team between men and women is of (0.133, 0.207)
The interpretation is that we are 99% sure that the true proportion is in this interval for the entire population, so the correct answer is given by option e.
