You build a model predicting blood pressure as a function of three variables: weight (numeric) age (numeric) income (categorical: low, medium, high) You first specify your model as: blood pressure ~ age * income + weight How many parameters (k) does your model have? (Remember, we do not count the grand mean in k) You change the above model specification to be: blood pressure ~ age * income + weight * income How many parameters does your model have now? You change your model to include the three-way interaction (which, remember, includes all two-way interactions and main effects, too!) Your model now looks like this: blood pressure ~ age * income * weight How many parameters does your model have now?
By implementing the concepts of Classes and Objects, write a C++ program that determines the horizontal and vertical displacement of a projectile, as well as the magnitude of the final velocity, at a given time, t, after the projection, Use the following formulas: x = Vo cos 0 ( t) y = Vo sin 0 ( t) - 0.5(9.8)t? Vx = Vo cos 0 Vy = Vo sin 0 –9.8(t) V= /Vx2 + Vy? The initial velocity, Vo, the angle of projection, 0, and the time, t, are to be entered from the keyboard. Accomplish the following for the given class diagram: Motion 1.) Create the class implementation using C++ Vo: double theta : double 2.) Using the constructor, create the object, M1 from t: double class Motion and store them in the stack memory. + Motion( Vo : double, theta : 3.) Implement the functions of the object. double, t: double ) + setVot(): void + setT(): void + Mx( ): double + My(): double + V(): double NOTE: The member function setVot() is used to enter the values of Vo and theta, 0, from the keyboard.

Prime Function A prime number is a positive integer that is evenly divisible only by 1 and itself. Write a predicate function called is_prime that accepts an integer parameter and returns true if that number is prime and false otherwise. Assume that the parameter is a positive integer. 57°F Clear 1 def is prime (num): 2 3 4 Check My Solution for i in range (2, num): if num % i == 0: return False return True Test Results: ✓ You are defining a function called is_prime. x The function does not return the correct value when the argument is 2.
