the great wall of china what did how learn about this structure that was a surprise to you or resonated with you about building relationships in the workplace did the people who built this wall have to work together are there any lessons to be learned about building relationships across philosophical divides(differing world views) in the workplace?

A merry go round (a disk I=(1/2) MR2, M=200 kg, R=2.0 m) rotates initially at 0.3 rad/s. A child of mass 40 kg is dropped onto the merry go round at a distance of 1.5 m from the axis of rotation. How fast is the child moving after it comes to turn with the merry go round?

Consider the following information about 2 shares P and Q

Share                  Expected return (yearly)                         Risk (standard deviation)

P                              8%                                                      7%

Q                             20%                                                     16%

The correlation coefficient between shares P and Q is 0.3

Required: Estimate the risk and expected return of a portfolio comprising 30% of share P and 70% of share Q and show your workings

What values would be stored in the given variables in each case?

a.          int n = 12 % 5;

b.          double x = 15 % 11 + 5.3 - 5 / (2.5 - 0.3);

c.   float y = 2 / (3.5 + static_cast<int>(3.5));

d.   bool z = (6 – 7 <= 2 * 1) && (5 + 4 >= 3) || (6 + 2 != 17 – 3 * 10);

Consider the standard Solow model with saving rate is 30%, and depreciation rate is 5%, Cobb-douglas production function with A = 1, α = 0.3.

Suppose initially the economy is at the steady state. If we increase the saving rate from 30% to 50% once for all.

Plot the first 20 periods of the following after the change:
• capital sequence • output sequence • consumption sequence

Convert the following decimal numbers into their 32-bit floating point representation (IEEE single precision). You may use a calculator to do the required multiplications, but you must show your work, not just the solution.

1. A gene has 3 alleles Wⁱ, W^o and W^p, with hierarchical dominance where Wⁱ (ivory) > W^o (orange) > W^p (pink). In a population of 1400 individuals the frequency of Wⁱ = 0.2 and W^o = 0.4.

1. What proportion of individuals in this population is expected to be heterozygous?

2. What proportion of the population will be ivory, orange and pink?

A single stage steam turbine is supplied with steam at 5 bars, 200 C at the rate of 50kgmin. It exhausts into a condenser at a pressure of 0.2 bars. The blade speed is 400msec. Nozzles are inclined at an angle of 20 to the plane of the wheel and outlet blade angle 30. Neglecting friction losses, the power developed by the turbine will be?

Given:

f(x,y) = 5 - 3x - y for 0 < x,y < 1 and x + y < 1, 0 otherwise

1) find the covariance of x and y

2) find the marginal probability density function for x

c) find the probability that x >= 0.6 given that y <= 0.2
