Answer:
D) 252.00
Step-by-step explanation:
Initial price of computer = $400
Less 30 % = -0.30 × 400 = - 120
Sale price = 280
Less 10 % = -0.10 × 280 = -28
Final price = $252
Isn’t it a poem?? And tbh it was good. I’d rate it a 8/10
F(x) = [(9,11),(-11,4),(7,-6),(11,-1), (-6,-15),(-13,-5)].

Using the inverse functions property:
- f⁻¹(f(93)) = m = 93
- f(7) = n = -6
<h3>
How to find the values of m and n?</h3>
Two functions f(x) and f⁻¹(x) are inverses if:
f( f⁻¹(x) ) = x
f⁻¹(f(x)) = x
We want to get:
f⁻¹(f(93)) = m
By using the above definition we get:
f⁻¹(f(93)) = m = 93
Now for the second one we want:
f(7) = n
If you look at the table, you can see that f(x) contains the point (7, -6), then:
f(7) = n = -6

Answer:
3/4
Step-by-step explanation:
Old x: 72 New x: 8
To get 6 (old y) from 72 (old x), multiply by 1/12
To get New Y, multiply 8 * 1/12 = 3/4
In the long run, you will lose $1 per game.
To find the expected value of this game, we have to multiply the chances by each prize. Then, add up all the possibilities.
(1/6) x $12 + (1/3) x $3 + (1/2) x $8
2 + 1 - 4 = -1
On average, you will lose $1 per game.
