Answer:
Step-by-step explanation:
Given
Required
Determine the test statistic
Let the dataset of stick be A and Liquid be B.
We start by calculating the mean of each dataset;
n, in both datasets in 6
For A
For B
Next, calculate the sample standard deviation
This is calculated using:
For A
For B
Calculate the pooled variance
Lastly, calculate the test statistic using:
We set
So, we have:
The equation becomes
<em>The test statistic is 31.29</em>
Answer:
That would be <u>x = -3</u>
Step-by-step explanation:
As long as the parabola points upwards or downwards, the axis of symmetry would be at the x-value of the vertex.
The epic ms-paint drawing describes some of that.
Answer:
<h2>
20 degrees</h2>
Step-by-step explanation:
This is a linear pair, whose sum always equals 180 degrees,
hence, we can set up the equation:
2z+140=180
2z=180-140
2z=40
z=40/2
z=20
Thus, the answer is 20 degrees
