What is an equivalent to -16m^2n-(-25m^2n)+(-7m^2n)
pantera1 [17]

Answer:

The equivalent expression is:

-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n

Step-by-step explanation:

Given the expression

-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a

=-16m^2n+25m^2n-7m^2n

\mathrm{Add\:similar\:elements:}\:-16m^2n+25m^2n-7m^2n=2m^2n

=2m^2n

Therefore, the equivalent expression is:

-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n

Semmy [17]

Answer:

The confidence interval for the difference of proportions of the population p2003-p2008 is 0.31\leq\Delta \pi \leq 0.37.

Step-by-step explanation:

In this question we have to construct a 90% confidence interval (CI) for a difference of proportions.

The proportion for 2003 is p_1=1085/1508=0.72.

The proportion for 2008 is p_2=570/1508=0.38.

The difference in proportions is \Delta p=p_1-p_2=0.72-0.38=0.34.

The standard deviation of the difference of proportions can be estimated as:

s=\sqrt{\frac{p_1(1-p_1)}{n_1}+\frac{p_2(1-p_2)}{n_2} }=\sqrt{\frac{0.72(1-0.72)}{1508}+\frac{0.38(1-0.38)}{1508} }=\sqrt{0.00029} =0.017

For a 90% CI, the z-value is 1.64.

Then we can construct the CI as

\Delta p-z\sigma\leq\Delta \pi \leq\Delta p+z\sigma\\\\0.34-1.64*0.017\leq\Delta \pi \leq0.34+1.64*0.017\\\\ 0.34-0.03\leq\Delta \pi \leq0.34+0.03\\\\0.31\leq\Delta \pi \leq 0.37
