Option D
<u>Answer: </u>
Shelter 4 has the highest percentage of black cats with 72%.
<u>Solution: </u>
Let us find the percentage of cats in each shelter of Marnie
Step 1:
4 of the 18 cats in Shelter 1 were black
This can be written as
= 0.22
Step 2:
13 of the 24 cats in Shelter 2 were black
= 0.54
Step 3:
12 of the 20 cats in Shelter 3 were black
= 0.60
Step 4:
18 of the 25 cats in Shelter 4 were black
= 0.72
Result:
Therefore we can conclude Shelter 4 has the highest percentage of black cats with 72%.

Answer:
This translates to "y is any real number such that it is 0 or larger".
The reasoning is that the result of any absolute value function is either 0 or positive. In other words, we'll never get a negative result of an absolute value function. This is due to how absolute value represents distance. Negative distance does not make sense.
So if y = |x-3| then y = 0 is the smallest output possible. We could have any positive output we want.
In terms of a graph (see below), the V shape is at the lowest point (3,0). The y coordinate is all we care about in terms of finding the range. So we see the lowest y value is y = 0.
