There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.
Hope you understand
Its pretty simple once you have the formula
Its 81 good job on the question
Answer:
The chain of supermarkets must order 428.1 gallons of milk.
Step-by-step explanation:
Let's define the random variable X.
X : ''Weekly volume of sales in thousands of gallons''
X is a continuous random variable.
The probability density function for X is
when 0 < x < 1
Otherwise.
Let's denote as ''a'' to the quantity of milk for the question.
We are looking for :





![a=1-\sqrt[7]{0.02}](https://tex.z-dn.net/?f=a%3D1-%5Csqrt%5B7%5D%7B0.02%7D)

a is in thousands of gallons, therefore the chain of supermarkets must order
428.1 gallons of milk in order to satisfy the question.
