PLEASE HELP <br><br> Solve using linear combination 8x + y = 14 3x + y = 4
yKpoI14uk [10]

Answer:

The solution of the linear system is:

x = 2 and y = -2

Step-by-step explanation:

The following linear equation is solved as follows:

8\cdot x  + y = 14

3\cdot x + y = 4

After some algebraic manipulation:

y = 14 - 8\cdot x

y = 4 - 3\cdot x

14 - 8\cdot x = 4 - 3\cdot x

10 = 5\cdot x

5\cdot x = 10

x = 2

And finally,

y = 4 - 3\cdot (2)

y = -2

The solution of the linear system is:

x = 2 and y = -2

A food safety guideline is that the mercury in fish should be below 1 part per million​ (ppm). Listed below are the amounts of m

Answer:

Confidence Interval: (0.44,1.00)

Step-by-step explanation:

We are given the following data set:

0.60, 0.74, 0.09, 0.89, 1.31, 0.51, 0.94

Formula:

\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}  

where x_i are data points, \bar{x} is the mean and n is the number of observations.  

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{:5.08}{7} = 0.725

Sum of squares of differences = 0.8809

S.D = \sqrt{\frac{0.8809}{6}} = 0.383

90% Confidence interval:  

\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}  

Putting the values, we get,  

t_{critical}\text{ at degree of freedom 6 and}~\alpha_{0.10} = \pm 1.943  

0.725 \pm 1.943(\frac{0.383}{\sqrt{7}} ) =0.725 \pm 0.2812 = (0.44,1.00)

No, it does not appear that there is too much mercury in tuna​ sushi.
