Your graph will look like an x (ok, the y axis is at a weird place in my plot). The solution (ie., the point where the two graphs intersect) is at (-1,1).
You can also calculate this by equating the two formulas:
x+y = x-y+2 => 2y = 2 => y=1, x =-1.
Range for a is 21
Range for b is 58
B has greater range
<em><u>There is no solution!</u></em>
Answer:
6.9%.
Step-by-step explanation:
Given that a university class has 26 students: 12 are art majors, 9 are history majors, 5 and are nursing majors, and the professor is planning to select two of the students for a demonstration, where the first student will be selected at random, and then the second student will be selected at random from the remaining students, to determine what is the probability that the first student selected is a history major and the second student is a nursing major the following calculations must be performed:
26 = 100
9 = X
9 x 100/26 = X
900/26 = X
34.61 = X
25 = 100
5 = X
500/25 = X
20 = X
0.2 x 0.3461 = X
0.069 = X
Thus, the probability that the first student selected is a history major and the second student is a nursing major is 6.9%.
