)Three companies A, B and C supply 25%, 35% and 40% of the notebooks to a school. Past experience shows that 5%, 4% and 2% of the notebooks produced by these companies are no of good quality. If a notebook was found to be bad quality, what is the probability that the notebook was supplied by A? )At Kennedy Middle School, the probability that a student takes Technology and Spanish is 0.087 The probability that a student takes Technology is 0.68. What is the probability that a student takes Spanish given that the student is taking Technology?

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
