The five marathon runners weigh an average weight of 92 pounds, Nicole weighs 89 pounds, Jon weighs 95 pounds, Jenny and Kim weigh 90 pounds each, How much does Jordin weigh?

Answers

Answer:

Jordin weighs 96 pounds

Step-by-step explanation:

The Mean Value of a Data Set

The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:

[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]

Where xi is the value of each data and n is the total number of values.

We are given the average weight of n=5 marathon runners:

[tex]\bar x=92[/tex]

Multiplying the formula by n and expanding the sum:

[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]

We are given the weighs of four of the runners:

[tex]5*92=89+95+90+90+x_5[/tex]

[tex]460=364+x_5[/tex]

Solving for x5:

[tex]x_5 = 460-364=96[/tex]

Norma is looking for a job cutting hair. One option is self-employment at The Seaside Salon, where she would pay $534 per month to rent a station and keep all of her earnings. Another option is to work at a franchise, where she would just have to pay the salon $3 for every haircut. If she performed a certain number of haircuts every month, the amount paid to either salon would be the same. How many haircuts would that be? How much would Norma pay?



If Norma performed__________ haircuts in a month, she would pay $____________ to either salon.

Answers

Answer:

If Norma performed 178 haircuts in a month, she would pay $534 to either salon

Step-by-step explanation:

Saloon 1:

Cost of saloon 1 = $534

Saloon 2:

Cost of saloon 2 = 3h

Where,

h = number of haircut

Equate the cost of renting either saloon

534 = 3h

h = 534 / 3

h = 178 hair cut

If Norma performed 178 haircuts in a month, she would pay $534 to either salon.
