The chord ab is a diameter of o. true or false.

False.

Step-by-step explanation:

We have been given a graph and a statement. We are asked to determine whether the given statement is true or false.

Statement: The chord AB is a diameter of O.

We know that diameter of a circle is a chord that passes through the center of the circle.

Upon looking at our given graph, we can see that chord AB doesn't pass through the center at point 'o', therefore, AB is not a diameter of circle O.

Therefore, the given statement is false.

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%
