Hello,
As h(x) is a bijection,
range(h(x))=dom(h^(-1)(x))={0,1,2,3}
Answer C
Answer:
First, 3 people divide $30, then each one of them pays:
$30/3 = $10.
Each one of them gets $1 in refound.
Then at the moment, each one of them paid $9, and there are 3 friends, so the total amount is 3*$9 = $27.
We also know that the cashier keeps $2, but these $2 must come from the $27 that the friends paid.
Then we will have $27 = $25 + $2.
This means that the total cost was $25, and the cashier kept $2 as a tip.
Now, in your problem, you add the $2 that the cashier kept to the $27 that the friends paid. While those $2 actually are already counted in the $27 that the friends paid.

Step-by-step explanation:
Answer: 84.5%
Step-by-step explanation:
15.2 × 15.2 = 231.04 cm² (area of the entire large square)
5.98 × 5.98 = 35.76 cm² (area of the small square)
large square - small square = area of the blue region
231.04 - 35.76 = 195.28 cm² (area of the blue region)
= percentage of time that the point will be in the blue region
= 0.845 --> 84.5%
