When intelligence test scores are used to make decisions about young children, developmentalists generally agree that: Question 15 options: A) Practitioners can confidently make decisions only about young children who fall within the "normal" range of intelligence. B) Test scores provide virtually no meaningful information about young children, and so their use in decision making is rarely defensible. C) Due to recent improvements in intelligence testing, practitioners can confidently make decisions about young children on the basis of test scores. D) Although scores often provide some useful information, they should always be used in conjunction with other sources of information.

John weighs 76 kg and following his warm-up, he exercises at 10.5 METs on a treadmill at Red Lerille’s Health Club. He was recently given a Monark stationary leg bike and he wants to exercise at the same workload as the treadmill; however, he doesn’t know what resistance setting or RPMs he should use. If you prescribed 70 RPMs as the pedaling rate, what would the resistance setting have to be to obtain a 10.5 MET workload? Round the answer to the nearest whole kg.

Saigon Shoes Company (SSC) manufactures and exports shoes. The sales manager is negotiating with a new customer, a French import company for an order of 450,000 pairs of a specific model for men. The cost accounting records of SSC (compare question 6) show that the total cost for stock valuation purposes for such a pair of shoes is USD 6.16, consisting of direct material cost of USD 3, direct labour cost of USD 3 and allocated fixed overheads of USD 0.16. The employees get a fixed monthly salary, and the company still has some capacity left to produce additional shoes. Normally, one pair of shoes for men is sold at a selling price of USD 9. The new customer is not prepared to pay that price and argues shoes from Bangladesh are considerably cheaper. Required: The sales manager of SSC is unsure what to do and she wants to know from you: a. Which is the lowest price (rounded up to full USD, which still results in a positive contribution) that the company could accept from the new customer, and b. under which conditions your statement would be valid. c. Please also calculate the additional contribution to fixed costs of that order at your suggested lowest selling price. d. What should be the price (rounded up to 2 digits after the decimal point) to that new customer, if SSC would like to achieve a contribution of 675,000 USD for that specific order. Answer:

MATLAB is a great tool for conducting numerical experiments involving well established governing equations. For a projectile motion application, the governing equation is: $R(\theta) = \frac{v^2}{g}\sin(2\theta)$ Where $R(\theta)$ is the range in meters, $v$ is the launch velocity, $g$ is the acceleration due to gravity, $g = 9.81 \text{ m/s}^2$. Complete the missing details in the MATLAB script below, one that: \begin{itemize} \item Computes $R$ as a function of $\theta$ given an initial velocity, $v$ of 120 m/s \item Uses \texttt{linspace} to create a dense array of 60 values for $0 \le \theta \le 90$. \item Generate a plot of R versus $\theta$. \item Computes and displays a value for a specific angle ($\theta_1$), $\theta_1 = 55^\circ$ \end{itemize} g = 9.81; v = 120; theta = linspace( ); R = v^2/g*sind(2*theta); plot( ); xlabel(' '); ylabel(' '); grid theta1 = R1 = v^2/g*sind(2*theta1) fprintf('%9.3f', R1) (a) Complete the missing details in the script. (b) At what value of theta is R a maximum? (c) What is the value of $R_1$ according to the fprintf format indicated?

6.10 Many home improvement retailers like Home Depot and Lowe's have low-price guarantee policies. At a minimum, these guarantees promise to match a rival's price, and some promise to beat the lowest advertised price by a given percentage. Do these types of pricing strategies result in Bertrand competition and zero economic profits? If not, why not? If so, suggest an alternative pricing strategy that will permit these firms to earn positive economic profits. 6.2 You are the owner of a local Honda dealership. Unlike other dealerships in the area, you take pride in your "No Haggle" sales policy. Last year, your dealership earned record profits of $2 million. In your market, you compete against two other dealers, and the market-level price elasticity of demand for mid-sized Honda automobiles is -1.2. In each of the last five years, your dealership has sold more mid-sized automobiles than any other Honda dealership in the nation. This entitled your dealership to an additional 25 percent off the manufacturer's suggested retail price (MSRP) in each year. Taking this into account, your marginal cost of a mid-sized automobile is $14,000. What price should you charge for a mid-sized automobile if you expect to maintain your record sales? Instruction: Round your answer to two decimal places.

Two rubber blocks are placed on a frictionless flat surface. One block, with mass 2.5 kg , is launched directly towards the second, which is stationary and has a mass of 7.0 kg . The two blocks have a perfectly elastic collision, launching the second block to the right with a speed of 6.0 m/s . What is the velocity of the first block after the collision, if "to the right" is considered the positive direction?

For this project, I need to analyze the Longitudinal Dynamic Stability of an aircraft using MATLAB. I am having trouble obtaining the transfer functions. I've inputted the stability parameters into the matrix and have arrived at this. >> A = [(s-Xu) -Xa g*cos(0); -Zu (s*V-Za) -V*s; 0 -(Mad*s+Ma) (s^2-Mq*s)] Transfer function 'A' from input 'u1' to output ... y1: s + 0.0291 y2: 0.251 y3: 0 Transfer function 'A' from input 'u2' to output ... y1: -15.32 y2: 243s + 152.8 y3: 0.26s + 2.118 Transfer function 'A' from input 'u3' to output ... y1: 32.2 y2: -243s y3: s^2 + 0.792s Continuous-time model. I don't know how to proceed because this doesn't look like it did when the professor demonstrated. Thanks in advance!
