Heart rate = ______ beats/min (2 pts)

Suppose the weights of Farmer Carl's potatoes are normally distributed with a mean of 8.5 ounces and a standard deviation of 0.8 ounces. Round your answers to 4 decimal places.

(a) If one potato is randomly selected, find the probability that it weighs less than 7 ounces.


(b) If one potato is randomly selected, find the probability that it weighs more than 10 ounces.


(c) If one potato is randomly selected, find the probability that it weighs between 7 and 10 ounces.

Use a 2 step binomial tree to value a new exotic derivative. Draw the tree and label the stock prices and derivative values at each node. The option expires in 6 months. The interest rate is 10% annually continuously compounded. The Strike Price (K) is 100. The spot price is at 100. U= 1.2 and D= 0.8 for each quarterly period. The payoff of this derivative is (ST/K). By this I mean that the payoff is the price of the underlying stock divided by the Strike Price.

A room 40 m x 15 m is to be illuminated by 1.5 m 80-W fluorescent tubes mounted 3.5 m above the working plane on which an average illumination of 180 lux is required. Using maintenance factor of 0.8 and the utilization factor of 0.5, (a) calculate the number of tubes required, (b) sketch a suitable layout. The 80-W fluorescent tube has an output of 4,500 lm.

ANS FOR A: 60 TUBES please show complete solution.

Consider the following economy with: IS curve YIS = k (AP – 123 R); LM curve YLM = 5 (M^s/P) + 499 R ; k = 3.95 ; AP = 5050 ; MS = 1980 . Derive the IS and the LM curves for P = 1.0. Find the interest rate and the output at equilibrium Find the equilibrium interest rates and outputs for the following price levels: 0.8; 1.2; 2.0. Plot the aggregate demand (AD curve) based on your findings in c.

True or False

1) A correlation coefficient based on a scatter plot measures the proportion of data lying on the regression line.

2)Which of the following is/are incorrect statement(s) about the correlation between two quantitative variables ?X and ?Y?

I. A correlation of -0.8 indicates a stronger linear association between X and Y than a correlation of 0.5.
II. A correlation of 0 implies ?X and ?Y are not related at all.
III. A correlation of -1 indicates that ?=−?Y=−X.

A Class I two-lane highway is on level terrain with passing permitted throughout. The highway has 3.6 m lanes with 1.1 m shoulders. There are 13 access points per kilometer. The base FFS is 96.5 km/hr. During the peak hour, 500 vehicles are traveling in the analysis direction and 400 vehicles are traveling in the opposing direction. If the PHF is 0.8 and there are 7% large trucks, 7% buses, and 7% recreational vehicles, what is the level of service?

Air enters the compressor of a regenerative air-standard Brayton cycle with a volumetric flow rate of 20 m³/s at 0.8 bar, 280 K. The compressor pressure ratio is 20, and the maximum cycle temperature is 1950 K. For the compressor, the isentropic efficiency is 92% and for the turbine the isentropic efficiency is 95%.


For a regenerator effectiveness of 86%, determine:

(a) the net power developed, in MW.

(b) the rate of heat addition in the combustor, in MW.

(c) the percent thermal efficiency of the cycle.

A 0.30 kg puck, initially at rest on a frictionless horizontal surface, is struck by a 0.20 kg puck that is initially moving along the x axis with a velocity of 2.4 m/s. After the collision, the 0.20 kg puck has a speed of 0.8 m/s at an angle of θ = 53° to the positive x axis.
