Mrs. Rowan allotted 30 minutes at the beginning of class for her students to complete an exam. The last student took 42 minutes to complete the exam. What is Mrs. Rowan's percent error?

Answers

Using percentage concepts, it is found that Mrs. Rowan percent error is of 40%.

  • The percent error is given by the extra time afforded multiplied by 100% and divided by the allotted time.

In this problem:

  • Allotted time of 30 minutes.
  • The last student took 42 minutes to complete the exam, thus the extra time afforded was of 12 minutes.

The percent error is:

P = (12)/(30) * 100\% = 0.4 * 100\% = 40\%

The percent error is of 40%.

A similar problem is given at brainly.com/question/16903296

Step-by-step explanation:

Percent error = |actual − theoretical| / actual × 100%

|42 − 30| / 42 × 100% = 28.6%

Y=-3x+24x-15 in vertex form

Answers

Answer: (4,-38) i think

Y = a(x-h)^2+k
First divide factor out -3 so Y = -3(x^2-8x+5)
Then complete the square:
Y = -3(x^2-8x+16+5-16)
Y = -3(x-4)^2+33
