I was gonna answer it but I'm in the wrong section I thought it was science then I saw it was math
Standard deviation=4.
let the mean be 12 and the score be 0 (therefore 12 point difference.)
0-12/s=-3 (s being standard deviation)
-12/4 = -3
Answer:
698.46 Hz
Step-by-step explanation:
A note an octave higher than another note is double the amount of frequency.
In this example, the note is 349.23 Hz. Doubled, this is 698.46 Hz. Therefore, the final answer is the first option, 698.46 Hz
Answer:
7pi/5
Step-by-step explanation:
A coterminal angle is the original angle ± 2pi radians
So to find a coterminal between 0 and 2pi you will need to substract 2pi's until you get one within that interval
17pi/5 - 2pi = 17pi/5 - 10pi/5 = 7pi/5
and this is already the answer ^

Answer:
25/416
Step-by-step explanation:
Maybe you want to know the value of ...
(1 1/4)/(20 4/5) = (5/4)/(104/5) = (5/4)×(5/104) = (5×5)/(4×104) = 25/416
