If finding the slope, the answer would be
m=3/2
Answer:
A
Step-by-step explanation:
We see that triangle QRS is located in Quadrant III. (See attachment for labelling of quadrants)
Reflecting it over the x-axis means that we flip it over the x-axis, or we flip it vertically. Doing so, QRS will end up in Quadrant II.
Now, we need to rotate QRS 180 degrees about the origin. The quadrants are all 90 degrees away from each other, which means that if we rotate QRS about the origin 180 degrees, we'll end up two quadrants away from Quadrant II: we'll end in Quadrant IV.
Look at each of the answer choices. The only choice that features Q'R'S' (the image of QRS) in the fourth quadrant is the first choice, or A. So that's the answer.

Answer:
Step-by-step explanation:
Tthe population is normally distributed and the sample size is .
Since the population standard deviation is unknown and the sample standard deviation , must replace it, the t distribution must be used for the confidence interval.
Hence with degrees of freedom of 21, .(Read from the t distribution table)
The 98% confidence interval can be constructed using the formula:
.
From the question the sample mean is dollars and the sample standard deviation is dollars.
We substitute the values into the formula to get
Therefore, we can be 98% confident that the population mean is between is between 19.22 and 44.78 dollars.
