Strep throat: Classically strep throat does not cause a cough. It's possible you have/ had a viral upper respiratory infection. These usually resolve within 1- 2 weeks.
What are the Means and Extremes of Proportions? A proportion is just an equation where two ratios are equal, and each piece of the proportion has a special name.
We can equivalently write  y is proportional to 1/ x , which y = c/x would represent. If a linear function transforms 0, a and b into 0, c and d, and if the product a b c d is not zero, we say a and b are proportional to c and d. An equality of two ratios such as, where no term is zero, is called a proportion. The force acting on a certain object due to gravity is directly proportional to the object's mass; the constant of proportionality between the mass and the force is known as gravitational acceleration.
