Answer:

There is no solution to these systems of equations.

Explanation:

To solve the system of equations: 6x−2y=5 and 3x−y=10, let us find the value of y in terms of x using second equation.

It is obvious that

3x=y+10 or y=3x−10

Now putting

y=3x−10 in first equation i.e.

6x−2y=5 , we get 6x−2(3x−10)= 5 or 6x−6x − 20 = 5 or −20 = 5, which is not possible

Step-by-step explanation:

6 x - 2y = 5

3x - y = 10/ (-1)

6x - 2y= 5

-3x +y = -10

6x - 2y =5

y= -10 +3x

6x - 2( -10 + 3x) = 5

y= -10 + 3x

6x + 20 - 6x = 5

y= -10 + 3x

0x= 5-20

y= -10 + 3x

(x,y) e 0 the system has no solution

The water diet requires you to drink two cups of water every half hour from the time you get up until you go to bed, but otherwi

Elan Coil [88]

Answer:

$7-3.182 \frac{13.638}{\sqrt{4}}= -14.698$

$7+3.182 \frac{13.638}{\sqrt{4}}= 28.698$

Step-by-step explanation:

For this case we have the following info given:

Weight before diet 180 125 240 150

Weight after diet 170 130 215 152

We define the random variable $D = before-after$ and we can calculate the inidividual values:

D: 10, -5, 25, -2

And we can calculate the mean with this formula:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

And the deviation with:

$s= \sqrt{\frac{\sum_{i=1}^n (X_i- \bar X)^2}{n-1}}$

And after replace we got:

$\bar D= 7, s_d = 13.638$

And the confidence interval for this case would be given by:

$\bar D \pm t_{\alpha/2} \frac{s_d}{\sqrt{n}}$

The degrees of freedom are given by:

$df = n-1= 4-1=3$

For the 95% of confidence the value for the significance is $\alpha=0.05$ and the critical value would be $t_{\alpha/2}= 3.182$ . And replacing we got:

$7-3.182 \frac{13.638}{\sqrt{4}}= -14.698$

$7+3.182 \frac{13.638}{\sqrt{4}}= 28.698$
