The answer is True.
A compound event is one in which there is more than one possible outcome. It is also defined as a probabilistic event with two or more favorable outcomes. For example, when you throw a die (singular for dice), it is called a simple event. On the other hand, when you throw a dice, it is known as a compound event.
For the circle of 3x² + 3y² = 75, the radius would be 5, and the center would be (0, 0)
This is because, usual circle equations have only 1 x² and y², so you can divide all terms by 3 to make the equation look normal. This gives you x² + y² = 25.
Since there is nothing being added or subtracted to the x and y values, the center is (0, 0), and the radius is the square root of whatever the values equal, which is √25 = 5.
I hope this helps!
If clark left at 7:43, and 30 minutes later he arrived he would get to school around 8:13, 7:43 + 30 = 8:13
Answer:

The most serious threat is mechanical problems.
Step-by-step explanation:
Given





Solving (a): The relative frequency table
The relative frequency (RF) is calculated as:

Where


So, the relative frequencies is as follows:





So, the relative frequency table is:

Solving (b): The most serious threat
The most serious threat is the one with the highest frequency, and that is the mechanical problems.
Carrying out maintenance schedule and removal of potential threat are some of the ways it can be minimized.
