Milk is delivered to a chain of regional supermarkets once a week. If the weekly volume of sales in thousands of gallons is a ra
sleet_krkn [62]

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

f(x)=7(1-x)^{6} when 0 < x < 1

f(x)=0   Otherwise.

Let's denote as ''a'' to the quantity of milk for the question.

We are looking for :

P(X>a)=0.02

P(X>a)=\int\limits^1_a {f(x)} \, dx

P(X>a)=\int\limits^1_a {7(1-x)^{6}} \, dx

P(X>a)=(1-a)^{7}

(1-a)^{7}=0.02

a=1-\sqrt[7]{0.02}

a=0.4281

a is in thousands of gallons, therefore the chain of supermarkets must order  

428.1 gallons of milk in order to satisfy the question.

Can 5yd, 12yd, 13,yd can it form a right triangle
HACTEHA [7]

Answer:

First one can

Second one can not

Step-by-step explanation:

13² = 5² + 12²

169 = 25 + 144

169 = 169 is a true statement

15² = 11² + 12²

225 = 121 + 144

225 = 265 is a false statement

So, not a right angle triangle
