(a) 1A 2A 3A 1B 2B 3B (6 possible outcomes
(b) Possible outcomes for A or 1 are 1A 2A 3A and 1B ( 4 outcomes) therefore:
Probabilty = 4/6 = 2/3
2x+6x+8=32
8x+8=32
-8 =-8
8x=24
8/8=x 24/8 =4
x=4
A(x1, y1), B (x2,y2)
d=V(y2-y1)^2+(x2-x1)^2
d^2= (1-4)^2+[5-(-2)]^2=(-3)^2+ (5+2)^2=9+49=58
d=V58
Answer:
inverse f-1 (x) = x/18
Step-by-step explanation:
To find the inverse of a function f-1 (x), we represent f(x) by y or let f(x) = y
then make x the subject of the formula,
f(x) = 18x
Let f(x) = y
hence Y = 18x, make x the subject of the formula, do that by dividing both sides by 18,
Y/18 = x or x = Y/18
Interchanging or swapping x and y, therefore f-1 (x) = x/18
therefore, F(x) = 18x, the inverse f-1 (x) = x/18
