0 0.07

25 0.12

50 0.17

75 0.14

100 0.28

125 0.18

150 0.04

We need to find the employee's expected earnings.

As we know the formula for "Expectation":

$E(x)=0\times 0.07+25\times 0.12+50\times 0.17+75\times 0.14+100\times 0.28+125\times 0.18+150\times 0.04\\\\E(x)=0+3+8.5+10.5+28+22.5+6\\\\E(x)=78.5$

Hence, the employee's expected earnings is 78.5.

Answer:

c ≈ 9.1 m

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

c² = 4.1² + 8.1² = 16.81 + 65.61 = 82.42 ( take square root of both sides )

c = $\sqrt{82.42 }$ ≈ 9.1 m ( to the nearest tenth )
