Step-by-step explanation:
5.
g(x)=-2x+1
let y=2x+1
Interchanging role of x & y
x=2y+1
y=½x-½
g-¹(x)=½(x-1)
not
equal to f(x)=-x+1
<u>Given function are not function of each other</u> .
6.
g(x)=-x
let
y=-x
Interchanging role of x & y
x=-y
y=-x
g-¹(x)=-x
not
equal to f(x)=3+⅓x
<u>Given function are not function of each other .</u>
Answer:
A. YES
B. NO
C. YES
Step-by-step explanation:
A. 100% = $24.30
24.3 x 0.85 = 85% = $20.66 (yes)
B. 100% = $55.80
55.8 x 0.85 = 85% = $47.43 (no)
C. 100% = $66.50
66.5 x 0.85 = 85% = $56.53 (yes)
10P4 = 10! / (10-4)! = 10*9*8*7 = 5040
9C4 = 9! / 5! 4! = 9*8*7*6 / 4*3*2*1 = 126
You have a 50% chance, or 1/2 to draw a red card
