A bucket is being dragged 50 meters up a vertical rock face. The bucket initially weighs 5 kg but gathers pebbles and sand as it slides against the rock face at a rate of .5 kg per meter. a) Convert the units. Make sure that the units for the force are Newtons (N=10*kg). b) Write the expression to F(x) as a linear function. c) Write an integral for the work required to lift the bucket 50 meters up. d) Find the value of the work (Ignore friction.).

T S Let \(\bar{X}_r\) and \(\bar{X}_s\) be the samples average of test and standard preparations in a potency test. If the standard preparations have mean and variance \(\mu_s\) and \(\frac{\sigma^2}{n}\) respectively and the test preparation 145 2 \sigma has mean \(\mu_t\) and variance \(\frac{\sigma^2}{m}\). Assuming the independence of the two samples, the distribution \(\bar{X}_r - \rho \bar{X}_s\) has mean 0 and variance \sigma^2 \left(\frac{1}{m} + \frac{\rho^2}{n}\right) therefore the appropriate confidence interval for p is 1 \left[\frac{\bar{X}_r}{\bar{X}_s} \pm \sqrt{\frac{\bar{X}_r^2}{\bar{X}_s^2} - (1 - g)\left(1 - \frac{t^2 s^2}{m \bar{X}_r^2}\right)}\right] 1 - g

Suppose Wacken, Limited just issued a dividend of $2.52 per share on its common stock. The company paid dividends of $2.02, $2.09, $2.26, and $2.36 per share in the last four years. If the stock currently sells for $71, what is your best estimate of the company cost of equity capital using arithmetic and geometric growth rates? Note: Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16. Answer is complete but not entirely correct. Cost of equity using arithmetic growth rate Cost of equity using geometric growth rate 3.49 % 3.51 %

6. A random sample is drawn from a normally distributed population with mean $\mu = 12$ and standard deviation $\sigma = 1.5$. a. What is the expected value and the standard error of the sampling distribution of the sample mean with $n = 20$ and $n = 40$. b. Can you conclude that the sampling distribution of the sample mean is normally distributed for both sample sizes? Explain. 7. A $\mu$ a.
