She can get $12. X= ($42)(2/7)
Slope intercept is x=3, y=-3. Hope this helped!
x will be 67 because in each case the angles are alternate interior angle so we can prove x=67degree
Using the t-distribution, the t-statistic for the two-sided test would be of t = 0.7.
<h3>What is the test statistic for a t-distribution hypotheses test?</h3>
The test statistic is given by:

The parameters are:
is the sample mean.
is the expected value.
- s is the standard deviation of the sample.
The values of the parameters are given as follows:
.
The sample mean is:

Hence the test statistic is:


t = 0.7.
