Hi there.
Let number of octaves be X.
Equation :
7x+1=36
7x=36-1
7x=35
X= 35/7
X= 5.
Therefore there are 5 number of black keys in an octave.
Hope it helps u.

Answer:
range = 18 and SD = 6
Step-by-step explanation:
range = max - min
= 228 - 210
= 18
FOR STANDARD DEVIATION * USE A SCIENTIFIC CALCULATOR THEY WON'T PENALIZE YOU*
follow these steps:
1. press mode then STAT
2. then press 1-VAR
3. put all the numbers on the table in ascending order
4 after press AC
5. press shift then 1
6. you will see many things but we are only interested in standard deviation, press *Var*
7. then select the standard deviation sign and press the equal sign
The first part is "increasing" the second part is "four"
The options for the first part were "increasing" and "decreasing"
The options for the second part were "two" and four"
Hope I helped.
Answer:
distance = speed × time
Step-by-step explanation:
The relationship between time, speed, and distance is expressed by the units we use to report speed:
speed = miles per hour
In generic terms, ...
speed = distance/time
To calculate distance, multiply both sides of this equation by time:
distance = speed × time
