Answer:

C=20 units (They didn't give the unit in the problem so if you want just write 20.)

Step-by-step explanation:

You need to solve for c. So first you have to use the equation.

We already know a and b so no we plug them in.

16^2 + 12^2 = c^2

When a number is squared or written as to the power of two you simply have to multiply that number by itself. So 16^2=256 and 12*12=144

256+144=c^2

c^2=400

Now we have to do another step because we don't want to know c^2 but want to know c. Now we have to find the square root of 400. The answer is 20 because 20*20=400.

Alright.
So, we have 2185 student in Rose.
Lily School has 307 more students than Rose, so Lily has,
2185 + 307 = 2492 Students in Lily School.
Since question a. is asking you to round off to the nearest ten, your answer to part a is 2490.

For part b. add 2185 and 2490.
2185 + 2490 = 4675 students.
The questions want you to round to the nearest hundredth, so,
4700 is the answer to part b.

The probability that a player will be asked a math question and then a music question is 0.03125

<h3>How to determine the probability?</h3>

The size of the sections are given as:

Music = 0.5

Sport = 0.5

Others = 1

So, the total size is:

Total = 0.5 + 0.5 + 1 + 1 + 1

Evaluate

Total = 4

The probability of asking a math question is:

P(Math) = 1/4 = 0.25

The probability of asking a music question is:

P(Music) = 0.5/4 = 0.125

The required probability is:

P(Math and Music) = P(Math) * P(Music)

This gives

P(Math and Music) = 0.25 * 0.125

Evaluate

P(Math and Music) = 0.03125

Hence, the probability that a player will be asked a math question and then a music question is 0.03125
