I added more just in case if a teacher needs the whole answer for some reason.
Answer:
Step-by-step explanation:
Area is 10x10=100+6x5=130
perimeter is 14+10+10+4+5+6
A perfect fifth above a note has a frequency ratio of 3 to 2.
Therefore, we can set the proportion:
164.81 : x = 2 : 3
which gives:
x = <span>164.81 </span>× 3 ÷ 2
= 247.21
Hence, the perfect fifth above E₃ will have a frequency of 247.21Hz which corresponds to a B₃.
It kind of looks like your missing something in you problem. But if f(x) = 3 is correct, then it doesn't matter what x is the answer is always going to be 3. So f(4.5) = 3. Most of the time though f(x) means a function of x, so there is an x in the problem. For example: f(x) = 3x, then f(4.5) = 3*4.5 = 13.5.
There are 3 even number: 2.4. and 6, so the probabilty of getting an even-numbered ball is 3/6, which is 0.5.
the same is getting an odd number, 0.5
