Multiply each X by its corresponding probability P, then add up them up.
E[X] = 3•0.2 + 4•0.1 + 5•0.25 + 7•0.05 + 9•0.4
⇒ E[X] = 6.2
Answer:
36
Step-by-step explanation:
25:9
25*4 = 100
9*4 = 36
Answer:
<em>a = 6 </em>
Step-by-step explanation:
g(x) = 5x - 2
h(x) = √(x + 3)
g(h(x)) = 5
- 2
g(h(a)) = 5
- 2
5
- 2 = 13
5
= 15
= 3
(
)² = 3²
a + 3 = 9
<em>a = 6</em>
