Answer:
Step-by-step explanation:
<u>Lets verify the ratio of corresponding sides:</u>
<u>Two sides are similar and the included angles are congruent as vertical angles:</u>
- LV/UV = MV/TV
- ∠MVL ≅ ∠TVU
- ΔMVL ~ ΔTVU by SAS

OK.
USUALLY when they give you this kind of graph (histogram),
each bar tells you the NUMBER of individuals that fall into
that particular range.
This graph is a little bit different ... it's easier.
On this graph, they're showing you the PROBABILITY that
an individual is in that particular range.
(The y-axis is labeled 'P', and they told us it's a "probability distribution".)
The graph is telling us that if you close your eyes and pick one giraffe,
he has a 25% chance of being 4 years old or younger, a 10% chance of
being between 4 and 8, a 35% chance of being between 8 and 12, and
a 5% chance of being between 16 and 20.
This is just a fancy, slightly confusing way of saying that 25% of the
giraffes in that zoo are 4 or younger, 10% of them are between 4 and
8, 35% of them are between 8 and 12, and 5% of them are between
16 and 20.
Before we worry about answering the question, we can spot a few
interesting things about the giraffe population at that zoo:
-- There are NONE that are between 12 and 16 years old. Weird.
-- The percentages only add up to 75%. So 25% of the giraffes
must be older than 20 ! They're just not included on the graph.
OK. So the question asks: What's the probability that a giraffe
you pick is between 8 and 20 ?
-- He's got a 35% chance of being between 8 and 12, no chance
at all of being between 12 and 16, and a 5% chance of being
between 16 and 20.
Can you see that his chance of being between 8 and 20 is
(35% + 0% + 5%) = 40% ?
It would be C because if you multiply each number of 6/2 by two you get 12/4. with B you divide by 3 to get 12/4. with D you divide by 20 to get 12/4. With C it isn't possible to get 12/4. So I would go with C
