Answer: The employee's expected earnings is 78.5.

Step-by-step explanation:

Since we have given that

$   Probability

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.

The perimeter of a rectangle is 72 m. The width of the rectangle is 16 m. What is the area of the rectangle?
liq [111]

Answer:

320m

Step-by-step explanation

a rectangle has four sides, two pairs of identical sides. So two sides are 16. So that adds up to 32. Perimeter is all sides added together. so it has to add up to 72. 72 minus 32 is 40, so two of the sides have to be 40. Area is length times width, so 16 times 20, which is 320.
