Answer:

Step-by-step explanation:

10 students like building snowmen but do not like skiing

so students who like both building snowman and skiing = 60 - 10 = 50

Total number of students who does not like building snowman and also does not like skiing = 80 - 60 = 20

Therefore, the probability that a student who does not like building snowmen also does not like skiing = 20/50 = 0.4

What is the inverse of this function

just olya [345]

G(x) = (25 - x)/5     First lets call g(x) by its other name - y

y = (25 - x)/5         Now switch the x and y

x = (25 - y)/5        Solve for y which is now the inverse - call this $g^{-1}(x)$

5x = 25 - y
y = 25 - 5x      this is the inverse so $g^{-1}(x)$ = 25 - 5x
