Me ayudan con esa ecuacion por sustitucion con la comprobacion pliss

attashe74 [19]

<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5

1/5x+3y/2=2 => (1/5)x + (3/2)y = 2

Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:

2x + 15y = 20

</span><span>Multiply the 1st equation by -1:

-</span>2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.

Solution is (10,0).

Suppose a population has a mean weight of 180 pounds and a standard deviation of 25 pounds. a sample of 100 items is drawn from

Angelina_Jolie [31]

Solution: We are given:

μ=180,σ=25,n=100

Therefore the standard error of the mean is

$\frac{standard deviation}{\sqrt{n}}$
