Answer:
41. f⁻¹(x) = -9x + 4
43. m⁻¹(x) = ∛(x-2)/4
Step-by-step explanation:
41. y = (4-x)/9
swap x and y: x = (4-y)/9
solve y: 9x = 4-y
y = -9x + 4
45. y = 4x³+2
x = 4y³+2
4y³ = x-2
y³ = (x-2)/4
y = ∛(x-2)/4
Let you do 42 and 46 by yourself
<span>Divide 800 / 20 = 40,
There will be 40 winners per draw.
800 / 100 = 8, 1% will be 8 people in the draw.
40 / 8 = 5, 5% of winning, 95% of loosing.
Hope this helps.</span>
