What are the two requirements for a density curve?

1 answer:

5 0

The density curve must satisfy two important conditions.

These two conditions are:
1- The total area under the density curve MUST BE equal to 1.
(Area total = 1)
2- Every point that is on the curve must have a vertical height that is equal to or greater than zero
(vertical height for each point ≥ zero)<span>
</span>

A function is a relation that maps to each input value exactly one output value.

Given the function as {(0,1), (2,3), (5,8), (7,2)}, you can rewrite it

f(0)=1;
f(2)=3;
f(5)=8;
f(7)=2.

Now consider all options:

the ordered pair (0,2) cannot be add to this function, because then f(0)=2, but you have already that f(0)=1 and output value should be one value;
the ordered pair (5,3) cannot be add to this function, because then f(5)=3, but f(5)=8 (given) and output value should be one;
the ordered pair (7,0) cannot be add to this function, because then f(7)=0, but f(7)=2;
the ordered pair (1,3) can be add to the set, because f(1)=3 is unique ordered pair (with 1st coordinate 1)

Answer:
$2 \frac{1}{4}$ cups

Explanation:
We know that one quart is equivalent to four cups. To know the number of quarts equivalent to 9 cups, we will simply use cross multiplication as follows:
1 quart ...............> 4 cups
?? quarts ...........> 9 cups

Number of cups = (9*1) / 4 = 2.25 = $2 \frac{1}{4}$ cups

Hope this helps :)
