If the occurrence of one event has no effect on the probability of another event, the two events are independent events.

B. Events: A - Neva is hungry, B - Neva buys a snack from the concession stand. Events A nd B are dependent (Neva buys snack, because she was hungry);

C. Events: A - Ari chooses a partner for a group project, B - then Ezekial chooses a partner from the remaining classmates. Events A nd B are dependent, because Ezekial's choice depends on Ari's choice.

D. Events: A - Luka paints during school, B - he stains his shirt. These events are dependent (Luka stains his shirt, because he was painting).

A. Events: A - The school play opens tonight, B - it is raining are independent events (school play opening doesn't depend on weather).

Answer:

$- 3x( - 4x + x) - x( - x - 2x) - 4x(4x + 3x) \\ \\ = 12 {x}^{2} - 3 {x}^{2} + {x}^{2} + 2 {x}^{2} - 16 {x}^{2} - 12 {x}^{2} \\ \\ = - 16{x}^{2}$

a book store cost $80 a day to keep open, and it spends $15 for each book that it sells. if each book sells for $23, what is the

aalyn [17]

The break even point for this book store is 10

Solution:

Given that, book store cost $80 a day to keep open, and it spends $15 for each book that it sells

Cost to open the book store = $ 80

The formula for solving the break even point (BEP) is:

$BEP = \frac{\text{Fixed cost}}{\text{Selling price - variable cost}}$

Fixed Cost is the cost that remains constant whether the services provided or products sold increases or decreases

Variable Cost is the cost that varies or differs in proportion to the products or services produced, whether they increased or decreased

In this problem,

Fixed cost = $ 80

Selling price = $ 23

Variable cost = $ 15

Therefore,

$BEP = \frac{80}{23-15}\\\\BEP = \frac{80}{8}\\\\BEP = 10$

Thus break even point for this book store is 10

In order for the bookstore to continue its business, it should sell at least 10 books to meet its $80 cost
