Answer:
(-3,4)
Step-by-step explanation:
That means to reflect the point across the y-axis... If you draw (3,4) on the coordinate plane you should see (-3,4) is the reflection across the y-axis from that point.

Step-by-step explanation:
If the probability that Yuri will make a free throw is 0.3, then the probability that Yuri will not make a free throw is 1-0.3=0.7.
1. The probability that Yuri will make two consecutive free throws is
2. The probability that he will make the first and not the second in two free throws is
3. The probability that he will make neither of the two free throws is
The answer to the question
Answer: About 2,688 ping-pong balls
Step-by-step explanation:
First, we will find how much space a ping-pong ball will take up.
-> A radius of 0.75 inches becomes a diameter of 1.5 inches
-> Then, we will pretend it is a cube with a side of 1.5 inches. Why? We do this because "the balls are stacked adjacent to and directly on top of each other."
V = a³
V = (1.5)³
V = 2.25 inches³
A ping-pong ball will take up 3.375 inches³.
Now, we will find the volume of the room.
V = L * W * H
V = 6 yards * 4 yards * 3 feet
V = 18 feet * 14 feet * 3 feet
V = 756 feet³
Lastly, we will divide the room by a ping-pong ball to find the number of ping-pong balls:
756 feet³ / 3.375 inches³
9,072 inches³ / 3.375 inches³
2,688 ping-pong balls
