i really dont know
Step-by-step explanation:
The probability distribution table is used to represent individual probabilities
The value of E(y) is 5.0
<h3>How to compute e(y)?</h3>
The value of e(y) is calculated using the following expected value formula

So, we have:

Evaluate

Hence, the value of E(y) is 5.0

Answer:
17 m² or 17 square meters
Step-by-step explanation:
A trapezoid has base lengths of 5 meters and 3.5 meters. If the height of the trapezoid is 4 meters, what is the area of the trapezoid?
Area of a trapezoid =1/2(b1 + b2)h
Where
b1 = First base length = 5m
b2 = Second base length = 3.5 m
Height = 4m
= 1/2(5m + 3.5m) × 4m
= 1/2(8.5m) × 4m
= 1/2 × 8.5m × 4m
= 17 m²
Therefore, the area of the trapezoid is 17 m² or 17 square meters

if your question is 
then this is 
<span>you can solve all quadratic equations using this method:
---
x^2 + 4x + 4 = 0
---
the above quadratic equation is in standard form, with a=1, b=4, and c=4
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
