Show your work, i have no idea how to do this

9. solve the exponential equation
1/16 = 64^(4x-3)

11. solve ln(5x + 7) = 8. round to the nearest thousandth.

12. use natural logarithms to solve the equation. round to the nearest thousandth.
5e^(2x+11) = 30

(that "e" is not a variable btw. it's e as in 2. i just wanted to make sure there was no confusion)

In a sample of 200 residents of georgetown county, 120 reported they believed the county real estate taxes were too high. develop a 95 percent confidence interval for the proportion of residents who believe the tax rate is too high. (round your answers to 3 decimal places.) confidence interval for the proportion of residents is up to . would it be reasonable to conclude that the majority of the taxpayers feel that the taxes are too high?

The accompanying table shows the numbers of male and female students in a particular country who received bachelor's degrees in business in a recent year. complete parts (a) and (b) below. business degrees nonbusiness degrees total male 189131 634650 823781 female 169539 885329 1054868 total 358670 1519979 1878649 (a) find the probability that a randomly selected student is male, given that the student received a business degree. the probability that a randomly selected student is male, given that the student received a business degree, is nothing. (round to three decimal places as needed.) (b) find the probability that a randomly selected student received a business degree, given that the student is female. the probability that a randomly selected student received a business degree, given that the student is female, is nothing. (round to three decimal places as needed.)

Ineeeeed this is due tomorrow and i dont know the answer can you find all the exponents
