After a reflection across line y=x the vertices of triangle P’Q’R’ are as follows
P’= (-1,-7)
Q’= (-8-7)
R’= (-3,3)
Answer:
Step-by-step explanation:
10+18+25+27+35+50=165
n=6
mean =165/6=27.5
x x- mean (x-mean)²
10 -17.5 306.25
18 -9.5 90.25
25 -2.5 6.25
27 -0.5 0.25
35 7.5 56.25
50 22.5 506.25
_____ ________
sum 0 965.5
_____ _________
standard deviation
The answer is 9 Dollars per hour because 36 divided by 9 is 4 and 9 times 9 is 81.
First you should set up fractions equal to each other to see the size ratio
8/34 = x/1.2
As to make comparable fractions. Then you would cross multiply in order to get
Divide both sides by 34 and you should get an answer of 0.28m for the model beam.
