In a certain clothing store, 6 shirts and 3 ties cost $79.50, and 3 shirts and 2 ties cost $41. Determine the cost of each tie.
Genrish500 [490]
6x + 3y = 79.5
3x + 2y = 41     y = -3/2x + 41/2      y = -1.5x + 20.5

6x + 3(-1.5x + 20.5) = 79.5
6x - 4.5x + 61.5 = 79.5
1.5x + 61.5 = 79.5
1.5x = 18
x = 12

Each shirt costs $12.
Now insert that number into the x to find the cost of each tie.

3(12) + 2y = 41
36 + 2y = 41
2y = 5
y = 2.5

Each tie costs $2.50.

Lyrx [107]

Answer:

832

Step-by-step explanation:

standard deviation =228 minute

error =13 minute given

confidence level =905% =0.90

α=1-0.90=0.1

z_\frac{\alpha }{2}=z_\frac{0.1}{2}=1.645

we know that sample size should be greater than

n\geq \left ( z_\frac{\alpha }{2}\times \frac{\sigma }{E} \right )^2

n\geq \left ( 1.645\times \frac{228}{13} \right )^{2}

n\geq 28.850^2

n\geq 832.3668

n=832
