Find the expected value of the random variable with the
following probability distribution:
X =
0
1
2.
4
3
5
Х
6
7
8

P =
.03
.15
.27
.20
.13
.10
.07
.03
.02

uhhh idk u yolo?

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
