In a simple economy, people consume only two goods: food and clothing. The market basket of goods used to compute the CPI has 65 units of food and 22 units of clothing.

The number N of devices that a technician must try to repair during the course of an arbitrary workday is a random variable having a geometric distribution with parameter p = 1/8. We estimate the probability that he manages to repair a given device to be equal to 0.95, independently from one device to another

a) What is the probability that the technician manages to repair exactly five devices, before his second failure, during a given workday, if we assume that he will receive at least seven out-of-order devices in the course of this particular workday?

b) If, in the course of a given workday, the technician received exactly ten devices for repair, what is the probability that he managed to repair exactly eight of those?

c) Use a Poisson distribution to calculate approximately the probability in part (b).

d) Suppose that exactly eight of the ten devices in part (b) have indeed been repaired. If we take three devices at random and without replacement among the ten that the technician had to repair, what is the probability that the two devices he could not repair are among those?

State whether the followings are True or False? (1) The angle of internal friction can vary from 0 to 90˚ since it is an angle. (2) A degree of saturation of 40% implies that 40% of the total volume consists of water. (3) Clays can have both cohesion and angle of internal friction. (4) In the triaxial test the horizontal plane is the major principal plane. (5) Piping (failure due high exit hydraulic gradient downstream) starts upstream and then progress to downstream face of a concrete dam. (6) It is safe to say that: in general natural soils in the field have larger permeability in the horizontal direction than the vertical direction. (7) Due to consolidation ∆? ?????????,?ℎ?? ? ?????????. (8) Consolidation is process of reducing voids by removing water and air if present. (9) In seepage in two dimensional impervious boundaries are equipotential lines. (10) Lowering the ground water table will increase the shear strength of the soil. (11) Due to consolidation the effective stress will increase. (12) Increasing the water pressure head at both upstream and downstream by 1 m will reduce piping.

Problem 19-17 EPS; options; convertible preferred; additional shares [LO19-4, 19-5, 19-6, 19-7, 19-8, 19-9]

On January 1, 2018, Tonge Industries had outstanding 460,000 common shares ($1 par) that originally sold for $25 per share, and 5,000 shares of 10% cumulative preferred stock ($100 par), convertible into 50,000 common shares.

On October 1, 2018, Tonge sold and issued an additional 12,000 shares of common stock at $35. At December 31, 2018, there were 21,000 incentive stock options outstanding, issued in 2017, and exercisable after one year for 21,000 shares of common stock at an exercise price of $32. The market price of the common stock at year-end was $50. During the year, the price of the common shares had averaged $42.

Net income was $600,000. The tax rate for the year was 40%.

Required:
Compute basic and diluted EPS for the year ended December 31, 2018. (Enter your answers in thousands.)
  

Connie Jefferson is the primary flower dealer in her hometown of San Flores. Connie has watched the sales volume of her favorite flower, the yellow rose, change over the past 10 weeks. The changes are due to an experiment that Connie is conducting. She has been told that she could sell more roses by reducing the price, and Connie tends to agree. In her experiment, Connie has set out to determine the relationship between the price charged for yellow roses and the quantity demanded. Over the past 10 weeks, Connie has carefully tracked the selling price of her roses and the quantity sold. Her data are as follows:

            a.         Develop a least squares regression equation that shows the relationship between the    

quantity of roses sold and the price charged.

            b.         If Connie sets the price at $17, what should be the demand for her roses?

            c.          Discuss the use of this modeling process in a different business setting.

*Please show working and please use the different answer from the chegg since my friends already use it. Handwriting is okay, thankyou and I appreciate it.

Pina Colada Corp. uses a perpetual inventory system reports the following for the month of June.

New attempt is in progress. Some of the new entries may impact the last attempt grading.Your answer is incorrect.

Calculate the average cost per unit, using a perpetual inventory system. Assume a sale of 430 units occurred on June 15 for a selling price of $7 and a sale of 55 units on June 27 for $8. (Round intermediate calculations to 0 decimal places, e.g. 5.250 and final answer to 3 decimal places, e.g. 5.125.)

Calculate cost of the ending inventory and the cost of goods sold for each cost flow assumption, using a perpetual inventory system. Assume a sale of 430 units occurred on June 15 for a selling price of $7 and a sale of 55 units on June 27 for $8. (Round intermediate calculations and final answers to 0 decimal places, e.g. 125.)

21. Teaching Methods A new method of teaching reading is being tested
on third grade students. A group of third grade students is taught using
the new curriculum. A control group of third grade students is taught
using the old curriculum. The reading test scores for the two groups are
shown in the back-to-back stem-and-leaf plot.

Key: 9 0 4 0 3 = 49 for old curriculum and 43 for new curriculum
At a = 0.10, is there enough evidence to support the claim that the new
method of teaching reading produces higher reading test scores than the
old method does? Assume the population variances are equal.
