Answer:
3.16
Step-by-step explanation:
Mean:
(12+14+5+13+11)/5
11
Sum of squares:
12²+14²+5²+13²+11²
655
Variance = 655/5 - 11²
= 10
sd = sqrt(10)

x=0 and y=
Step-by-step explanation:
We need to solve the system by elimination and find values of x and y
Subtract eq(1) and eq(2)
Now Multiply equation (1) by 2 and subtract with eq(2)
So, x=0 and y=

(-5,2) is located in the II quadrant because the x is negative and the y is positive.
(5,-5) is located in the IV quadrant because the x is positive and the y is negative.
(2,-5) is also located in the IV quadrant because the x is positive and the y is negative.
(-4,-5) is located in the III quadrant because both x and y are negative.
Answer:
Sequence 1: Translate 5 units to the right, and 5 units down
Sequence 2: Reflect across the origin, translate 1 unit down, 1 unit to the right
Step-by-step explanation:
Chose 1 point to focus in, such as (-1, 1)
Move that point 5 units to the right, and 5 units down. See how it matches up with the same corner of the red square?
Now, use that same point, and change the signs of both the x and y, this is to reflect across the origin. (In reality, you are just reflecting across the x and y axis)
So you originally have: (-1,1) -> (1, -1)
Now move this point one unit to the right, and 1 unit to the left.
It may seem that you made it touch the wring corner, but do the same thing with another corner's points. They all flipped!
