Consider the effect of the transformation (x,y) to (x,2y) on the parallelogram ABCD with vertices A (0,0), B(1,1), C(3,1), D(2,0). Select true or false for each statement. A. The transformation preserves parallelism A True B False B. The transformation preserves distance A True B False C. The transformation preserves angle measure A True B False
Step-by-step explanation:
A'(0,0),B'(1,2),C(3,2),D(2,0)
it is a parallelogram.
vertical distance is doubled. so false.
angle changes so false.

Find the number of distinguishable permutations of the word "VANQUISH".
Answer:
40320
Step-by-step explanation:
no . of permutation of n different things taken all together is given by n!
n! = n*(n-1)*(n-2).......3*2*1
given that
we have to find number of distinguishable permutations of the word "VANQUISH"
here n = number of different letters in vanquish = 8
thus,
required permutation = 8! = 8*7*6*5*4*3*2*1 = 40320

Scores on a mathematics assessment test for eighth-graders have a mean of 283, a 10th percentile of 232, a 25th percentile of 255, a 75th percentile of 304, and a 90th percentile of 327. Interpret each of these numerical descriptive measures. Interpret the mean value of 283. Choose the correct answer below. A. For this problem, the mean value of 283 represents the variation in the test scores on a mathematics assessment test for eighth-graders. B. For this problem, the mean value of 283 represents the range of test scores on a mathematics assessment test for eighth-graders. C. For this problem, the mean value of 283 represents the average test score on a mathematics assessment test for eighth-graders. D. For this problem, the mean value of 283 represents the middle test score when the scores are arranged in ascending (or descending) order.
Answer:
C ) For this problem, the mean value of 283 represents the average test score on a mathematics assessment test for eighth-graders.
Step-by-step explanation:
10 th percentile of 232
10 % below 232 and 90 % above 232
25 th percentile of 255
25 % below 255 and 75 % above 255
75 th percentile of 304
75 % below 304 and 25% above 304
90 th percentile of 327
90 % below 327 and 10 % above 327 .
So counting is from below to above in ascending order .
the mean of 283 represents the average of the test score
Hence option C ) is correct .
The score of the mathematics test for the 8th class have a mean of 283 and the 10th percentile of 232, a 25th percentile of 255 nd so on.
As per the question the 10 th percentile of 232 , hence the 10 % below 232 and 90 % above 232 . The 25 % below 255 and 75 % above 255 , 75% below 304 and 25% above 304. The 90 % below 327 and 10 % above 327 . So in ascending order the mean of 283 represents the average of the test score. Hence the option C is correct.Learn more about the mathematics assessment test for eighth-graders.
