Question Continuous variable \( \mathrm{X} \) is uniformly distributed the interval \( [4,34.5] \). The density function of continuous variable \( \mathrm{Y} \) is given by \[ f_{Y}(y)=1 / 14,0 \leq y \leq 14 \text { and } f_{Y}(y)=0 \text {, otherwise. } \] What is the slope of their quantile plot (or curve), \( d y / d x \), equal to? Answer:

Q1. [8 points) The elevator in the car rental building at San Francisco International Airport has a placard stating that the maximum capacity is "4000 16-27 passengers. Because 4000/27 is approximately 148, this converts to a mean passenger weight of x = 148 lb when the elevator is full. We will assume a worst-case scenario in which the elevator is filled with 27 adult males. Let's assume that adult males have weights that are normally distributed with a mean of 189 Ib and a standard deviation of 39 lb. a. Find the probability that 1 randomly selected adult male has a weight greater than 148 lb. Use normaldist (u) PX>148) P(z>(148-189)-P( 21.5) -0.853 b. Suppose that we randomly select samples of 27 adult males and compute the sample mean for each sample Use the Central Limit Theorem to calculate the mean and standard error of sample means in the sampling distribution HU 0 C. Would it be appropriate to model the sampling distributions of sample means with a normal distribution? Explain d. Suppose that in a particular random sample of 27 adult males, the mean weight is 148 lbs. Find the Z-score for Search D

GB Timbers, based in Germany, supplies timber products to construction and manufacturing industries. The company reported after-tax earnings available to common stocks of RM3,200,000. From these eamings, the management decided to pay a dividend of RM0.80 on each of its 4,000,000 common shares outstanding. The capital structurë of the company includes 30% debt, 40% common stock, end 30% preferred stock. The tax rate applicable to GB Timbers is 30%.i) If the market price of the common stock is RM3.60,) and dividend is expected to grow at a rate of 8% per year for the foreseeable future, Ahat is the required rate of return on the company's common stock? (2 marks) ii) The company can issue a RM1.00 dividend preferred stock for a market price of RM10.00 per share. The floatation costs would amount to RMO.60 per share. What is the cost of preferred stock financing? (2 marks) iii) In addition, the company can issue RM100 per value, 8% coupon, 10 year bonds that can be sold for RM110 each. Floatation costs would amount to RM2 per bond. Use the estimation formula to figure the approximate cost of debt financing. (2 marks) iv) What is the Weighted Average Cost of Capital (WACC)? (2 marks)

A company records its employees movement In and Out of office in a table with 3 columns (Employee id, Action (In/Out), Created) Employee id Action Created 1 In 2019-04-01 12:00:00 1 Out 2019-04-01 15:00:00 1 In 2019-04-01 17:00:00 1 Out 2019-04-01 21:00:00 There is NO sample data for this question. You only need to submit the queries Please solve first 2nd and 4th it is bit confusing. Find number of employees inside the Office at current time Find number of employees inside the Office at “2019-05-01 19:05:00” Measure amount of hours spent by each employee inside the office since the day they started (Account for current shift if she/he is working) Measure amount of hours spent by each employee inside the office between “2019-04-01 14:00:00” and “2019-04-02 10:00:00”

Show all work and explain. The rigid bar is supported by the two short white spruce wooden posts and a spring. 50 kN/m А с B k 1 m -1 m -1 m Part A If each of the posts has an unloaded length of 1 m and a cross-sectional area of 850 mm² , and the spring has a stiffness of k = 4 MN/m and an unstretched length of 1.02 m , determine the force in each post after the load is applied to the bar. Express your answer to three significant figures and include appropriate units.
