The relationship between variance and standard deviation is :
Standard deviation = sqrt (variance),
Variance = standard deviation^2.

Answer:
24 cm³
Step-by-step explanation:
Volume of a cylinder is three times of a cone with same measurements
volume of cone is 8cm³
then,volume of cylinder is 8 × 3 = 24
The equation to model this would be 65 = 11r + 9s.
In this equation, we know that the total number he works is 65. We also know he burns 11 every time he runs for an hour. Therefore we can multiply 11 by r. We also know he burns 9 for every hour he spends swimming. Therefore we can multiply 9 by s.
When we put all three of these things together, we get 65 = 11r + 9s.
Answer:
y = 24
Step-by-step explanation:
3x + y = 6
Solve for y
Subtract 3x from each side
3x -3x+ y = 6-3x
y = 6-3x
Let x = -6
y = 6 -3(-6)
=6+18
=24
The diagram shows that angle AQB = angle BQC
So 5x= 8x-24
3x= 24
x=8 (first answer)
AQB= 5(8) = 40 (second answer)
BQC= 8(8)-24 = 64-24 = 40 ( third answer)
AQC = AQB+ BQC
AQC= 40+40 = 80 (Fourth answer)
