List all elements of each set: The set of all positive proper fractions with a denominator of 7

The set of all positive proper fractions with a denominator of 7 is .

Step-by-step explanation:

A proper fraction is of the form where the numerator is less than the denominator, i.e. x < y.

A set is a collection of items that belong to a certain experiment. Every member of a set are known as elements.

In this case we need to form a set of all positive proper fractions with a denominator of 7.

So, it is provided that y = 7.

Then the value of x has to be positive and less than 7, i.e. 1 < x < 7.

The set is:

Thus, the set of all positive proper fractions with a denominator of 7 is .

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
