How to solve system graphically 4y = x + 8, x = 2/3y +2

1 answer:

5 0

4y = x + 8
x = 2/3y + 2
4y = x + 8
2/3y = x + 2
3 1/3y = 8 
3 1/3 3 1/3
 y = 2 2/5
4(2 2/5) = x + 8
 9 3/5 = x + 8
 -8 -8
 1 3/5 = x
 (x y) = (1 3/5, 3)

Unusual

Step-by-step explanation:

Given that a tobacco company claims that the amount of nicotine in its cigarettes is a random variable with mean 2.2 mg and standard deviation .3 mg.

i.e. population parameters are

$\mu =2.2 \\s = 0.3$

The approximate probability that the sample meanwould have been as high or higher than 3.1

$=P(X\geq 3.1)\\=P(Z\geq \frac{3.1-2.2}{\frac{0.3}{\sqrt{100} } } )\\=P(Z\geq 30)\\$
