Since in each option, each input is mapped to only one output, all the options are correct.

<h3>When a relationship represents a function?</h3>

A relationship represents a function when each input is mapped to only one output.

In this problem:

For the Venn sets, only one line departs each value of x, hence it is a function.

For the ordered pairs, each value of x(2, 5 and -4), is mapped to only one value of y, hence it is a function.

The graph has no vertically aligned points, hence it is a function.

Thus all the options are correct.

How do you find the perimeter of triangle ABC?

shusha [124]

Alright, so we'll use the Pythagorean Theorem for this one.
⇒ a²+b²=c²

The hypotenuse of a triangle is represented by c² and we're given the values for a and b. For this triangle, we'll make 15 = a and 20 = b. Plug this into the equation and we'll have (15)<span>² + (20)² = c ². This gives us 625 = c</span>². Solve for c by square rooting both sides of the equation. √(625) = c. We now know that c = 25. To take the perimeter, we add a + b + c ⇒ (15) + (20) + (25) = Perimeter.

-Hope this helps!

Answer:

(a) The population of interest in this situation is the average age of visitors to the park in MAY during weekdays or weekends.

(b) Two samples are described in the above situation, that is;

A survey of 100 randomly selected park visitors on a weekday in May.
A survey of 100 randomly selected park visitors on a Saturday in May.

(c) The average age of 37 years is a statistic.

(d) The above information represents a quantitative variable.

(e) The possible explanation for the large difference in age between the two samples would be that during weekdays most of the teenagers or children below 20 years of age are not able to come to parks because of their schools, coachings or some studies related work.

Step-by-step explanation:

We are given that a research firm regularly conducts customer satisfaction surveys for an amusement park. A survey of 100 randomly selected park visitors on a weekday in May concluded the average age of visitors to the park was 37 years.

When the survey was repeated with 100 randomly selected park visitors on a Saturday in May the average age of visitors to the park was determined to be 17 years.

(a) The population of interest in this situation is the average age of visitors to the park in MAY during weekdays or weekends.

(b) Two samples are described in the above situation, that is;

A survey of 100 randomly selected park visitors on a weekday in May.
A survey of 100 randomly selected park visitors on a Saturday in May.

(c) The average age of 37 years is a statistic as it is the sample average age of visitors to the park on a weekday, i.e. $\bar X_1$ = 37 years.

(d) The above information represents a quantitative variable because in this we are concerned about the average age of visitors in the park which is a numeric value and we are not interested in any qualitative aspect.

(e) The possible explanation for the large difference in age between the two samples would be that during weekdays most of the teenagers or children below 20 years of age are not able to come to parks because of their schools, coachings or some studies related work.

But during weekends like Saturday, the schools or coaching institutions are generally closed due to which they are able to come to parks to play and because of this there are large number of children below 20 years of age who visit parks on weekends.
