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:

The correct option is 4.

Step-by-step explanation:

It is given that figure ABCD is transformed to figure A′B′C′D′.

The vertices of ABCD are A(1,1), B(3,3), C(4,2) and D(4,1).

The vertices of A'B'C'D' are A'(1,-3), B'(3,-1), C'(4,-2) and D'(4,-3).

It is clear that the figure translate 4 units down and the rule of translation is

Translation is a rigid transformation, it means image and preimge are congruent.

Since ABCD is translate 4 units down to make A′B′C′D′, therefore

Congruent part of congruent figures are congruent.

Therefore the correct option is 4.

I Hope It's Helpful :)
