On a U. S. Flag that is 19 feet by 10 feet, the union is LaTeX: 7\frac587 5 8 feet by LaTeX: 5\frac385 3 8 feet. For each question, first estimate the answer and then compute the actual percentage. What percentage of the flag is taken up by the union?

Asimple random sample of size nequals14 is drawn from a population that is normally distributed. the sample mean is found to be x overbar equals 70 and the sample standard deviation is found to be sequals13. construct a 90% confidence interval about the population mean

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

If 20% of a number is 35, what is 50% of that number?
