Step-by-step explanation:
The lower limit of the interval is 0.712 if the survey of 504 citizens found that 378 of them favor a new bill introduced by the city.
<h3>What is a confidence interval?</h3>
It is defined as the sampling distribution following an approximately normal distribution for known standard deviation.
We have:
A survey of 504 citizens found that 378 of them favor a new bill introduced by the city.
Sample proportion = p = 378/504 = 0.75
q = 1 - p = 1 - 0.75 = 0.25
![\rm SD = \sqrt{\dfrac{pq}{n}}](https://tex.z-dn.net/?f=%5Crm%20SD%20%3D%20%5Csqrt%7B%5Cdfrac%7Bpq%7D%7Bn%7D%7D)
![\rm SD = \sqrt{\dfrac{0.75\times0.25}{504}}](https://tex.z-dn.net/?f=%5Crm%20SD%20%3D%20%5Csqrt%7B%5Cdfrac%7B0.75%5Ctimes0.25%7D%7B504%7D%7D)
SD = 0.01928
For 95% confidence interval Z value = 1.96
Lower limit = 0.75 - 1.96(0.01928)
= 0.712
Thus, the lower limit of the interval is 0.712 if the survey of 504 citizens found that 378 of them favor a new bill introduced by the city.

Answer:
y = 1
x = -1
Step-by-step explanation:
- 4x + 11y = 15
2 = 2y
Find y from the second equation
2 = 2y
2/2 = 2y/2
1 = y
Substitute y into the first equation.
- 4x + 11y = 15
- 4x + 11(1) = 15
- 4x + 11 = 15
-4x = 15 - 11
-4x/-4 = 4/-4
x = -1
