The Powerball lottery is open to participants across several states. When entering the powerball lottery, a participant selects

five numbers from 1-59 and then selects a powerball number from the digits 1-35. In addition, there’s a $1 million payoff for anybody selecting the first five numbers correctly. • Show that the odds of winning the Powerball Jackpot are 1 in 175, 223, 510. • Show that the odds of winning the $1 million are 1 in 5, 153, 632. On February 18, 2006 the Jackpot reached $365 million. Assuming that you will either win the Jackpot or the $1 million prize, what’s your expected value of winning?

The area of a rectangular flower bed is 24 square feet. The perimeter of the same flower bed is 22 feet. What are the dimensions
Ray Of Light [21]

ANSWER

B. 3 ft by 8 ft

EXPLANATION

The area is given as 24 square feet.

This implies that,

l \times w = 24

The perimeter of the rectangular field is given as 22 feet.

This implies that,

2(l + w) = 22

Or

l + w = 11

We make w the subject in this last equation and put it inside the first equation.

w = 11 - l

When we substitute into the first equation we get;

l(11 - l) = 24

11l -  {l}^{2}  = 24

This implies that,

{l}^{2}  - 11l + 24 = 0

(l - 3)(l - 8) = 24

l = 3 \: or \: 8

When l=3, w=24

Therefore the dimension is 3 ft by 8 ft

Cost: 120 and 52

Profit equation:

\frac{Net sales-COGS}{Net Sales} =Profit

\frac{(132+46.8)-(120+52)}{(132+46.8)}

Simplify:

\frac{6.8}{178.8} =.03803 or 3.803% Profit
