Answer:

Inequalities work exactly like equations with one exception. The process begins just like equations: first, do the opposite of what you see, then do the same thing on the other side of the sign. At the last step of solving an inequality, if you multiply or divide by a negative number, then you reverse the sign

Suppose that a school has 20 classes: 16 with 25 students in each, three with 100 students in each, and one with 300 students, f
astraxan [27]

Answer

a)   y    |      p(y)

    25   |      0.8

   100   |     0.15

   300   |      0.05

E(y) = ∑ y . p(y)

E(y) = 25 × 0.8 + 100 × 0.15 + 300 × 0.05

E(y) = 50

average class size equal to E(y) = 50

b)  y    |      p(y)

    25   |     \dfrac{16\times 25}{1000}=0.4

   100   |     \dfrac{3\times 100}{1000}=0.3

   300   |      \dfrac{1\times 300}{1000}=0.3

E(y) = ∑ y . p(y)

E(y) = 25 × 0.4 + 100 × 0.3 + 300 × 0.3

E(y) = 130

average class size equal to E(y) = 130

c) Average Student in the class in a school = 50

  Average student at the school has student = 130
