A student is taking a 10 question multiple choice test that has five options for each question (A, B, C, D, and E). Suppose a student knows the correct answer to 6 of the questions. For the remaining 4 questions, the student can

eliminate one response per question, on average.

What is the probability the student gets at least an 80% on the test?

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
