In days she used 55.8 pounds in total
so your answer is 55.8
Answer:
Your graph would start at the point 0,2 (over 0 up 2). Other points would be (2,8), (4,14), (-2,-4), and so on. A good website for graphing is Desmos.com .you can plug an equation in and it will graph it for you!
Step-by-step explanation:
The Bernoulli distribution is a distribution whose random variable can only take 0 or 1
- The value of E(x2) is p
- The value of V(x) is p(1 - p)
- The value of E(x79) is p
<h3>How to compute E(x2)</h3>
The distribution is given as:
p(0) = 1 - p
p(1) = p
The expected value of x2, E(x2) is calculated as:
So, we have:
Evaluate the exponents
Multiply
Add
Hence, the value of E(x2) is p
<h3>How to compute V(x)</h3>
This is calculated as:
Start by calculating E(x) using:
So, we have:
Recall that:
So, we have:
Factor out p
Hence, the value of V(x) is p(1 - p)
<h3>How to compute E(x79)</h3>
The expected value of x79, E(x79) is calculated as:
So, we have:
Evaluate the exponents
Multiply
Add
Hence, the value of E(x79) is p
