Answer:
Expectation number of books a customer will purchase = 1.3
Step-by-step explanation:
x : 0 1 2
p(x) :0.2, 0.3, and 0.5
Expectation
E(X) = ∑x P(x)
= 0 X 0.2 +1 X 0.3+ 2 X 0.5
= 1.3
Expectation E(X) = 1.3
Expectation number of books a customer will purchase = 1.3

Answer:
Step-by-step explanation:
V = length * height * width = 18 * length * width
2,592 = 18 * length * width ; divide both sides by 18
144= length * width ; now what 2 numbers multiplied are giving us 144?
1*144 = 144 ; 2*72 = 144 ; 3*48=144 ; 4*36 =144 ; 6*24 = 144 ; 8*18 = 144 ;
9*16 =144 ; 12*12 =144
5, 7, 10 and 11 does not divide 144 into a whole number
possible lengths and widths are: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
5(x−10)=275
(5)(x)+(5)(−10)=275(Distribute)
5x+−50=275
5x−50=275
5x−50+50=275+50
5x=325
5x5=3255
x=65
Answer:
x=65
