The problem says: 
Solve the pair of equations by graphing.
Here's how:

In each pair:

-- Solve the first equation for 'y'.
   (Put it in the form of  y=m₁x+b₁ .)
-- Graph the straight line with slope=m₁ and y-intercept=b₁ .

-- Solve the second equation for 'y'.
   (Put it in the form of  y=m₂x+b₂ .)
-- Graph the straight line with slope=m₂ and y-intercept=b₂ .

-- The solution to the pair of equations is the point
where the two lines cross.

One senior from the high schools will be selected at random. What is the probability that the senior selected will not be from h
DochEvi [55]

Using the probability concept, it is found that there is a 0.7361 = 73.61% probability that the senior selected will not be from high school b given that the senior responded with a choice other than college.

<h3>What is a probability? </h3>
  • A <em>probability </em>is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Researching the problem on the internet, it is found that:

  • 538 seniors responded with a choice other than college.
  • Of those students, 99 + 83 + 49 + 31 + 63 + 71 = 396 are not from high school b.

Hence:

p = \frac{396}{538} = 0.7361

0.7361 = 73.61% probability that the senior selected will not be from high school b given that the senior responded with a choice other than college.
