Using a random sample of 5613 tv​ households, acme media statistics found that 25.1 % watched the final episode of ​"when will it end question mark​"
a. find the margin of error in this percent.
b. write a statement about the percentage of tv households in the population who tuned into the final episode of ​"when will it end question mark​"

answer:

90° counterclockwise rotation

plot the situation

answer:

the rule would rotate the figute 270° clockwise is: (x,y)→(-y,x)

the coordinate would be the output for point a' is (4,0)

step-by-step explanation:

when you make a rotation of 270° clockwise of a point p=(x,y), the coordinates of the new point will be p'=(-y,x). then, the rule would rotate the figue is (x,y)→(-y,x)

in this case the point:

a=(0,-4)=(xa,ya); xa=0, ya=-4

the output would be:

a'=(-ya,xa)=),0)→a'=(4,0)
