Two state parks, elm grove and cathedral rock, each recorded the number of visitors to the park each day for 15 days. the parks made line plots from the data recorded.

what statement about the two plots' distributions is true?

a. the degree of overlap between the two distributions is high.
b. the degree of overlap between the two distributions is moderate.
c. the degree of overlap between the two distributions is low.
d. there is no overlap between the two distributions.

Step-by-step explanation:

Overlapping can be defined as the intersection between areas of two normal distributions. The overlap means that sample or populations have similarities, which occasionate this behaviour.

In this case, we have two normal distributions (you can deduct that observing the bell form). If you look closely, you'll observe that the tails of theses distributions overlap, but just the tail, that means they have a low degree of similarity.

Therefore, the right answer is C, the degree of overlap is low.

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.
