Answer:

B

Step-by-step explanation:

When interpreting a confidence level, we say that if we were to select many random samples of the same size from the same population and construct a 95% confidence interval using each sample, about 95% of the intervals would capture the true proportion of registered voters that plan vote for the incumbent president.

Need help pls. I try many ways of this answer
LekaFEV [45]

Answer:

3(t+2)

Step-by-step explanation:

As with any problem involving division of fractions, you can invert the denominator and multiply.

Your knowledge of the factoring of the difference of squares helps. If that doesn't work for you, you can always use synthetic division or polynomial long division to find the quotient of (t^2-4) and (t-2).

\displaystyle\frac{\frac{4t^2-16}{8}}{\frac{t-2}{6}}=\frac{4(t^2-4)}{8}\cdot\frac{6}{t-2}\\\\=\frac{3(t+2)(t-2)}{t-2}=3(t+2)
