the standard error of the proportion is _%
the number of people who are satisfied with the policy if between _% and _%
all answers are appreciated you

Answer with explanation:

Sample Size = 1200

it is also given that 80% of the respondents were not satisfied with the policy,Means 20% of the respondents were satisfied with the policy.

80% of 1200=960

20% of 1200 =240

Standard error of the proportion

= 0.0115 (Approx)

=0.0115×100

=1.15%

→→20% of the respondents are satisfied with the policy.

So, the number of people who are satisfied with the policy is between 20-1.15=18.85% and 20+1.15=21.15% that is (18.85%,21.15%).

the image of (6, 9) under a dilation is (4, 6). the scale factor is

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
