We have n = 100 many random variables xi 's, where the xi 's are independent and identically distributed bernoulli random variab

Alex777 [14]

Recall that for a random variable $X$ following a Bernoulli distribution $\mathrm{Ber}(p)$ , we have the moment-generating function (MGF)

$M_X(t)=(1-p+pe^t)$

and also recall that the MGF of a sum of i.i.d. random variables is the product of the MGFs of each distribution:

$M_{X_1+\cdots+X_n}(t)=M_{X_1}(t)\times\cdots\times M_{X_n}(t)$

So for a sum of Bernoulli-distributed i.i.d. random variables $X_i$ , we have

$M_{\sum\limits_{i=1}^nX_i}(t)=\displaystyle\prod_{i=1}^n(1-p+pe^t)=(1-p+pe^t)^n$

which is the MGF of the binomial distribution $\mathcal B(n,p)$ . (Indeed, the Bernoulli distribution is identical to the binomial distribution when $n=1$ .)

A popcorn container is the shape of an inverted cone. it is 9 inches tall, and the circular opening has a diameter of 4 inches.

Tamiku [17]

The expression that determines the volume of the container is $V = \frac 13 * \pi * 2^2 * 9$

<h3>How to determine the volume expression?</h3>

The given parameters are:

Shape = Cone
Height, h = 9 in
Diameter, d = 4 in

The volume of the cone is calculated using:

$V = \frac 13 * \pi (d/2)^2h$

So, we have:

$V = \frac 13 * \pi (4/2)^2 * 9$

This gives

$V = \frac 13 * \pi * 2^2 * 9$

Hence, the expression that determines the volume of the container is $V = \frac 13 * \pi * 2^2 * 9$

One gallon is approximately 3.79 liters. Write a direct variation equation that relates 2 gallons to y liters.

8090 [49]

Answer:

2 gallons x 3.79 = 7.58 liters

Step-by-step explanation:

1 gallon = 3.79 liters

so

2 gallons x 3.79 liters = 7.58 liters

2 x 3.79 = y liters
