Answer:
the width of sue's interval will be narrower than javier's.
Step-by-step explanation:
in this problem, i do believe that sue's interval will be more narrow. in the formula,
p-hat ± 
,
a larger "n" value will lead to a smaller standard error. given that the population proportion is the same for both, and the sample size is the only difference, the standard error of sue's interval will be smaller than javier's, therefore making her whole confidence interval smaller.
again, i do believe this is correct, this is what i have in my AP stat notes. hope this helps!
Answer:
She received 99,267
Step-by-step explanation:

Answer:
Step-by-step explanation:
Simplifying
1.4x + 3.5y = 0
Solving
1.4x + 3.5y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3.5y' to each side of the equation.
1.4x + 3.5y + -3.5y = 0 + -3.5y
Combine like terms: 3.5y + -3.5y = 0.0
1.4x + 0.0 = 0 + -3.5y
1.4x = 0 + -3.5y
Remove the zero:
1.4x = -3.5y
Divide each side by '1.4'.
x = -2.5y
Simplifying
x = -2.5y
B) insulation is the answer!!
