Answer:
Step-by-step explanation:
The null hypothesis is usually the default statement. The alternative is the opposite of the null and usually tested against the null hypothesis
In this case study,
The null hypothesis in would be that the mean time between clicks of the second hand on a particular clock is 1 second. In symbolic form it would be u = 1
The alternative hypothesis would be that the mean time between clicks of the second hand on a particular clock is 1 not second. In symbolic form, it would be: u =/ 1
Answer:
The perimeter of the rectangle would be 15m.
Step-by-step explanation:
P=2(l+w)=2·(4.9+2.6)=15
<span>Basically, you have five bigger pieces compared to five smaller pieces. So 5/8 is greater than
5/10. When the numerators are the same, we don't have to worry about
converting any numbers. Let's look at like fractions (same
denominators). SO YEAH</span>
The break even point for this book store is 10
<em><u>Solution:</u></em>
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
<em><u>The formula for solving the break even point (BEP) is:</u></em>

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,

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
