Consider the following scenario: a student has prepared a series of analytical solutions to be run on an instrument in another room. the student has worn gloves throughout the preparation of the solutions, and has wiped up all drips and spills that occurred during that process. the student removes her gloves before leaving the lab room and carries her solutions in scintillation vials in a large clean beaker to the room where the instrument is located. once in the new room, the student obtains a new pair of gloves before dispensing the solutions for analysis. which of the following changes could improve the student's procedure?

If it is possible for the student to wear a hand glove while transporting the chemicals to the other room, and use her other hand to open doors and use elevators.

It is also better if she could with her teammate and they could share responsibilities such that one of them carries the solutions while the other opens doors and uses the elevator.

A less breakable or plastic bin could have been used to convey the solutions to the other room to prevent the use of bare hand from contacting the glassware.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
