Answer: The population proportion is between 0.34 and 0.46 .
Step-by-step explanation:
Interpretation of 95% confidence interval : A person can be about 95% confident that the true population parameter lies in the interval.
A confidence interval is constructed for an unknown population proportion, p. A sample is collected, and the 95% confidence interval is calculated to be 0.40 ± 0.06.
i.e. Lower limit = 
Upper limit = 
i.e. 95% confidence interval = (0.34, 0.46)
i.e. A person can be about 95% confident that the true population proportion (p) lies in the interval (0.34, 0.46).
⇒ It is most accurate to say that there is approximately 95% confidence in the assertion that:
The population proportion is between 0.34 and 0.46 .

Answer:
y=11
x=8
Step-by-step explanation:
This is Elimination
2x+2y=38
Subtract 2x on both sides 2y=-2x+38
Then Multiply 2(y=x+3) which equals 2y=2x+6
Solve by Elimination
2y=-2x+38
2y=2x+6
add the y's and since the x's are different those cancel out, then add 38 and 6.
then you do the equation 4y=44
divide both by 4
y=11
then you do 11=x+3
subtract 3 on both sides
x=8
and there you go
I hope this is how you wanted it solved
