Answer:
44.3%
Step-by-step explanation:
For a single selected traveler the change of him being high volume is 0.85, for 5 is the product of each individual probability.
P=(0.85)^5=0.443 → 44.3%

Answer:
(x, y, z) = (-1, 0, -3)
Step-by-step explanation:
We notice that the coefficients of z are such that elimination of the z term from the equations is made easy.
Adding equations 1 and 2:
(2x -3y -2z) +(x +3y +2z) = (4) +(-7)
3x = -3
x = -1
Adding equations 2 and 3:
(x +3y +2z) +(-4x -4y -2z) = (-7) +(10)
-3x -y = 3
Substituting for x, we get ...
(-3)(-1) -y = 3
0 = y . . . . . . . . . . . add y-3 to both sides
Then z can be found from any equation. Substituting for x and y in the second equation gives ...
-1 +2z = -7
2z = -6 . . . . . add 1
z = -3 . . . . . .divide by 2
The solution is (x, y, z) = (-1, 0, -3).
25 to 2 means for every 25 students there are 2 teachers.
Divide the total number of teachers by their ratio:
190 / 2 = 95
Now multiply that by the student ratio:
95 * 25 = 2,375 total students.
