C is your answer. Because 8 times 1.75$ = $14.00 and 5 times 1.25= $6.25. So $14.00+ $6.25 = $20.25

The measure of angle θ is 7pi/4 . The measure of its reference angle is *Blank* °, and tan θ is *blank*

sukhopar [10]

Since the measure of angle $\Theta$ is $\frac{7\Pi }{4}$

The measure of its reference angle = $\frac{7\times 180^{\circ}}{4}$

= $=315^{\circ}$

Now we have to compute the value of $\tan \Theta$

$\tan \Theta = \tan \frac{7\Pi }{4}$

$= \tan (2\Pi -\frac{\Pi }{4})$

The value of ( $(2\Pi -\frac{\Pi }{4})$ ) lies in the fourth quadrant. In fourth quadrant, the value of tan is always negative.

So, $\tan (2\Pi -\frac{\Pi }{4})$

$= -\tan (\frac{\Pi }{4})$

= -1.

True or false: when comparing two populations, the larger the standard deviation, the more dispersion the distribution has,

SOVA2 [1]

True, because the standard deviation describes how far, on average, each observation is from the typical value. A larger standard deviation means that observations are more distant from the typical value, and therefore, more dispersed.

forty volunteer drivers are separated into two groups of 20 drivers each at random. The first group is asked to pay particular a

ale4655 [162]

The reasonable conclusion is that the randomization distribution provides strong evidence that the difference in the means for the two treatments group is due to the treatment because the difference is highly unlikely based on random assignment error.

<h3>How to explain the information?</h3>

Given the mean for the first group is 43.16 gallons of gas and that the mean for the second group 54.63 gallons of gas. The difference in the means for the two groups is - 11.47 gallons of gas.

Here, the data for both groups are combined and redistributed at random into two groups of 20. The histogram shows that the distribution is approximately symmetric. Therefore, the randomization technique can be used.
