I believe that it is C, mind you I could’ve got it wrong. It’s been awhile since I’ve done that kind of math.
The customer drawing a 30% discount card then the next customer 20% discount card has a probability of 5/40 for the 30% which = 12.5% and 20% is 15/40 which = 37.5% add them together then divide by 2 for a total of 25%.
The customer drawing a 10% card has a 20/40 which = 50% then a customer drawing a 20% card is 15/40 = 37.5% add them together then divide by 2 = 43.75%
The customer drawing a 10% card has a 20/40 which is 50%. Then another customer drawing another 10% is another 50% add them together and divide by 2 = 50%
The customer drawing a 20% card has a 5/40 which is 12.5% and another customer drawing a 20% card again is 12.5%. Add together and divide by 2 = 12.5%. So your answer is the 1st three.
Volume of cylinder = πR².H
Volume Sphere: =4/3πR³
Volume of cylinder = Volume Sphere (given), then:
πR².H = 4/3πR³
Simplify==> R².H = (4/3)R³==> H = (4/3)R===> R=3H/4
The solution of the given equation is +9 and -9.
Step-by-step explanation:
Given,
To find the solution of x.
or, 
or, 
or, x = ±
[ square roots has two values so we put ±]
or, x = ±9
