Step-by-step explanation:
all points move in the same direction and equal distances and also they are directly congruent and then find the translation vector ( there is no slash)
Answer: C. 
Step-by-step explanation:
The confidence interval for difference of two population mean is given by :-
Given : Level of significance : 
Then , significance level : 
Critical value : 
Hence, a 99% confidence interval for the difference between the mean wait times of everyone who rode both rides
First simplify the section in the parenthesis.
-1/6 + 2/3(8 1/4) + -1/2
Then multiply 2/3 by 8 1/4.
-1/6 + 5 1/2 + -1/2
Add -1/2 to 5 1/2.
-1/6 + 5
Add 5 to -1/6.
4 5/6 is the fully simplified answer.
Hope this helps!
Answer: x=1,y=0
Step-by-step explanation:
X-2y=1.....equation 1
2x-y=2.....equation 2
X=1+2y.......equation 3
Substitute equation 3into 2
2(1+2y)-y=2
2+4y-y=2
2+3y=2
3y=2-2
3y=0
Y=0/3
Y=0
Substitute for y=0 in equation 1
X-2y=1
X-2(0)=1
X-0=1
X=1
X=1 & Y=0
