Answer:
The MOE for 80% confidence interval for <em>μ </em>is 5.59.
Step-by-step explanation:
The random variable <em>X</em> is defined as the number of square feet per house.
The random variable <em>X</em> is Normally distributed with mean <em>μ</em> and standard deviation <em>σ</em> = 137.
The margin of error for a (1 - <em>α</em>) % confidence interval for population mean is:

Given:
<em>n</em> = 19
<em>σ </em>= 137

Compute MOE for 80% confidence interval for <em>μ </em>as follows:

Thus, the MOE for 80% confidence interval for <em>μ </em>is 5.59.
Ok so isolate the y in the second equation.
3x+2y=-9
y=-2x-7
now you know what y has to equal so input it wherever there is a y
3x+2(-2x-7)=-9
try to solve that, if you still need help comment and ill give u the answer
Answer:
- first you find out what is amount of time that k is then
- divide, multiply, subtract, and then you add if you want to
