Answer:
W'(27,45)
Step-by-step explanation:
First we must fnd the scale factor of the dilation and then multiply the coordinates of W(3,5) by the scale factor.
Let k be the scale factor of the dilation centered at the origin.
The mapping for a dilation by a scale factor k is
But we were given the coordinates of the image, which is
Q'(-27,36)
Comparing coordinates:
We could compare the first coordinates too and get the same result.
The image of W(3,5) is given by:
Answer:
c. The researcher must compute an estimated standard error for the mean difference score to compute a t statistic.
Step-by-step explanation:
As already defined that repeated-measures experiments measure the same set of research participants two or more times, while matched-subjects experiments study participants who are matched on one or more characteristics.
Both repeated-measures experiment and a matched-subjects experiment when used to compare two treatment conditions use the same t statistic. Therefore, researcher must compute an estimated standard error for the mean difference score to compute a t statistic.
34 ÷ 8 = 4 (remainder 2)
4 2/8 = 4 1/4
So another name for 34/8 as a mixed number is 4 1/4. I hope this helps!
