Four resistors when connected in series give an equivalent
resistance if 75.0 Ω. Three of the resistors have values 18.0 Ω, 6.0 Ω, and
24.0 Ω, respectively. What is the resistance of the fourth resistor?
1. A six pumpkins are displayed in a store a population consists of 6 values (19,14,15,9,10. and 17). Suppose that random sample size 2 are taken form this population
a. How many samples are possible? List them and compute the mean of each sample
b. Construct the sampling distribution of the sample means
c. Construct the histogram of the sampling distribution of the sample means

Write a program in C++ that defines a class named StringOps. Declare data members of
this class as described below:
variable str of data type string.
variable size of data type integer which represents the length of the string str.
A sinusoidal wave traveling in the positive x direction has an amplitude of 15.0 cm, a wavelength of 40.0 cm, and a frequency of 8.00 Hz. The vertical position of an element of the medium at t = 0 and x = 0 is also 15.0 cm, Determine the phase constant , and write a general expression for the wave function

$500 is deposited in an account which bears 12%p.a interest compound monthly. Use the compound interest formula to find the number of years it would take to accumulate $500 to $806.11
Under perfect competition the rising firms marginal cost curve above minimum of avarage variable cost is what?
Defi ne the concept of a supply schedule or curve. Show that an increase in supply means a rightward and downward shift of the supply curve. Contrast this with the rightward and upward shift of the demand curve implied by an increase in demand.
Write a program in C++ that defines a class named Student that represents a student. This
class declares three variables – name, stipend and course of suitable data types. It also has
a variable intern_status that is set to 1 if the student is interning in some organization and
0 otherwise. This variable is initialized appropriately in the constructors of the class. The
member functions of this class should be defined as given below:
Parameterized constructor that initializes the values of all the members.
An overloaded constructor that sets the stipend to zero for a non-interning student.
Copy constructor for the class Student.
Overload Operator << as a friend function in the class Student for displaying the
details of the student.
Destructor for the class Student.
In the main() function, create two objects of this class; one for a ststuden
to create a new object and display it using << operator.
