A reflection across the line y=0 (AKA the x-axis)
and then across the line x=0 (AKA the y-axis)
is the same as a rotation of 180º
clockwise about the origin because the lines intersect at the origin and at a 90º angle.
While all of that is true, you could also be more general, because reflecting over any two lines that intersect at the origin will result in a rotation about the origin and have an angle of rotation equal to twice that of the acute angle formed between the intersecting lines.
Answer:
y intercept = (0,-1.2)
x intercept = (3.6,0)
Step-by-step explanation:
For y-int, x=0
3(0)-9(y)=10.8
9y=-10.8
y= -1.2
For x-int, y =0
3x - 9(0)=10.8
3x=10.8
x=3.6
Answer:For the first one 26.73 would turn into 27 and 89.42 would stay 89
Step-by-step explanation: Any number that is 5 or greater can be used to round any number.

Answer:
b) Both 1,004 and 251 are greater than 10.
Step-by-step explanation:
p = 0.80
n = 1255
In order to use CLT the distribution of
should have np and n(1-p) greater than 10.
np = 1255*0.80
np = 1004
n(1-p) = 1255*0.20
n(1-p) = 251.00
Since Both 1004 and 251 are greater than 10,
