The steps to do this :
Answer: ~ 34.15%
Step-by-step explanation:
To calculate the percent error for the amount of snowfall, you can use the following formula:
Percent Error = [(|Estimated Value - Actual Value|) / Actual Value] * 100%
In this case, the estimated snowfall is 6.75 inches, and the actual snowfall is 10.25 inches. Plugging these values into the formula:
Percent Error = [(|6.75 - 10.25|) / 10.25] * 100%
Percent Error = [(3.5) / 10.25] * 100%
Percent Error ≈ 34.15%
So, the percent error for the amount of snowfall is approximately 34.15%. This means that the estimated snowfall was about 34.15% lower than the actual snowfall.

Answer:
To calculate the size of the serving angle A in the diagram of the volleyball court, you can use trigonometry.
You have the following information:
The distance from point A to point C is 9 meters.
The distance from point A to point B is 31 meters.
To find angle A, you can use the inverse tangent (arctan) function:

Rounded to the nearest degree, the size of the serving angle A is approximately 73 degrees.
Step-by-step explanation:
Sure, I'll explain it in a simpler way:
Imagine you're standing at point A on the volleyball court, and you want to serve the ball towards point C or point B. Point C is 9 meters away, and point B is 31 meters away from you.
To find out how wide the angle is between where you stand (point A) and where you want to serve the ball (between points C and B), we can use a special math trick. It's like saying, "How much do I need to aim to the left or right?"
We use something called "arctan" to figure it out. When we do the math, we find that the angle A is about 73 degrees. So, you need to aim your serve at about a 73-degree angle to get the ball between points C and B on the other side of the court.

Answer:
Option 3 -
Step-by-step explanation:
Given : Options in the figure.
To find : Which of the following is a complex number?
Solution :
Complex number is defined as the number which contains real number along with imaginary number.
The complex number is in the form of a+ib.
Now, we determine one by one.
Option 1 - -7
-7 is the real number not complex.
Option 2 -
is the real number not complex.
Option 3 -
is in the form a+ib so it is a complex number.
Option 4 -
is the real number not complex.
Therefore, Only option 3 is the complex number.
