What is the length of segment xy?

4.5 units
/45 units
/53 units
9 units

The correct option is (C) √53 units.

Step-by-step explanation:  We are given to find the length of the line segment XY in the graph.

We know that the length of a line segment is equal to the distance between its end points.

DISTANCE FORMULA: The distance between two points with co-ordiantes (a, b) ad (c, d) is given by

From the graph, we note that

the co-ordinates of the point X are (-4, 0) and the co-ordinates of the point Y are (3, 2).

Therefore, the distance between the points X and Y is given by

So, the length of the line segment XY is √53 units.

Option (C) is correct.

a

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
