A hairdresser is deciding where to open her own studio. If the hairdresser chooses Location A, she will pay $1200 per month in r
Ymorist [56]
She will need to cut 26.6 haircuts a month a location A to break even (1200/45 = 26.6) so roughly 27 haircuts to make a profit


She will need to cut 30 haircuts at location B to break even (1800/60 = 30) and 31 hair cuts to see a profit.


She will need to cut 30.67 haircuts at location A and 33 haircuts at location B to make the same profit at either location (Roughly $180).


30.67 x 45 = 1380.15 - 1200 = 180

33 x 60 = 1980 - 1800 = 180

egoroff_w [7]

Answer:

0.45576

Step-by-step explanation:

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

Standard Deviation = √variance

Mean = 50

= √9

= 3

z = 51 - 50/3

= 0.11111

Probability value from Z-Table:

P(x<51) = 0.54424

P(x>51) = 1 - P(x<51)

= 1 - 0.54424

= 0.45576

The probability that the dealer will sell 51 or more cars is 0.45576
