What is the y-coordinate for the solution of the system of equations below? 7y+5x=19 3y+5x=7
RoseWind [281]
I would go about solving this by elimination because the x variables are already the same so all you would have to do is change one equation to the opposite signs and add them, so it would look like:

7y + 5x = 19
+ -3y - 5x = -7
-------------------
4y=12
y=3

A new anxiety medication has been manufactured and a study is being conducted to determine whether its effectiveness depends on
Irina18 [472]

The test statistics is used to determine if the anxiety medication can happen under a null hypothesis

The test statistics that is an appropriate hypothesis test is z =\frac{0.35 - 0.40}{\sqrt{\frac{0.35(1 - 0.35)}{60} + \frac{0.40(1 - 0.40)}{85}}}

<h3>How to determine the test statistic</h3>

<u>40 milligrams of medication</u>

Patients = 60

Lower stress level patients = 21

The mean of this medication is:

\bar x = \frac{x}{n}

So, we have:

\bar x_1 = \frac{21}{60}

\bar x_1 = 0.35

<u>75 milligrams of medication</u>

Patients = 85

Lower stress level patients = 34

The mean of this medication is:

\bar x = \frac{x}{n}

So, we have:

\bar x_2 = \frac{34}{85}

\bar x_2 =0.4

The test statistic is then calculated as:

z =\frac{\bar x_1 - \bar x_2}{\sqrt{\frac{\bar x_1(1 - \bar x_1)}{n_1} + \frac{\bar x_2(1 - \bar x_2)}{n_2}}}

The equation becomes

z =\frac{0.35 - 0.40}{\sqrt{\frac{0.35(1 - 0.35)}{60} + \frac{0.40(1 - 0.40)}{85}}}

Hence, the test statistics that is an appropriate hypothesis test is z =\frac{0.35 - 0.40}{\sqrt{\frac{0.35(1 - 0.35)}{60} + \frac{0.40(1 - 0.40)}{85}}}
