The graph of a proportional relationship will always be a straight line that passes through the origin. Why?

Mathematics
1 answer:
sashaice [31]3 years ago
5 0

Answer:

Being proportional between two entities, refers to the 'Constant of Proportionality' that would be fixed between them which establishes a relationship between them when multiplied or divided.

If we considered it on a graph, the 'Constant Of Proportionality' may take any real values between the coordinate pairs x and y [x,y]. As even 0 is a real number, it will surely be a constant of proportionality when multiplied since its product would result in itself (0). Hence, both x and y turns 0.

As the coordinates of the origin are always (0,0), the graph  (Or the slope) would surely pass through the origin.

Example :

If we consider a graph such that x=y.

And if we multiply or divide any real number (a) between them.

ax=ay

As a is a variable, and can take the value of 0, the graph can pass through the origin as x and y nullify becoming the coordinates of the origin.

Scott ran 11 kilometers in nine days. One mile is approximately 1.6 kilometers. About how many miles did Scott run?
natita [175]

Scott run 6.875 miles in nine days.

Step-by-step explanation:

Given,

Distance covered by Scott = 11 kilometer

1.6 kilometer = 1 mile

We will find the unit rate in terms of kilometer;

1 kilometer = \frac{1}{1.6}\ miles

11 kilometers = 11*unit rate of kilometer

11 kilometers = 11*\frac{1}{1.6}

11 kilometers = 6.875 miles

Scott run 6.875 miles in nine days.

Keywords: unit rate, multiplication

A group of researchers wants to develop an experiment to determine whether a new drug effectively treats cancer. The researchers
yawa3891 [41]

Part A: The animals are used for examining and determining the effect of a particular new drug for the treatment of the diseases and disorders before they are examined over humans. This practice is called as clinical trial.

The ethical issue associated with given type of testing is that animals have right to live and survive. They should not be subjected to the treatment where they experience harm or even death.

Part B: Those assigned to the control take a sugar pill. The only thing you want to vary across groups when you're conducting an experiment is the treatment. Since taking pills is a part of taking medication (the treatment), medical experiments often employ something called a placebo-controlled study where outcomes for those who are randomly assigned to take the medication are compared to outcomes for those who are randomly assigned to take a sugar pill. The sugar pill is expected to have no effect, so it serves as a useful baseline to compare the treatment to.
