Answer:

This is incomplete you can edit and report this answer as not the answer you was looking for. 125-70 is 55 stamps among 5 friends this is either 11 stamps each but some have two together so if it is an odd number like 13 or 17 together then you type in T = 17  O=55-17= ? and you have your answer for the other three.

Mr. Starnes wondered what proportion of Katy Perry's Twitter followers are
Citrus2011 [14]

Answer and Step-by-step explanation:

To calculate a confidence interval for a proportion:

1) Determine the proportion

p=\frac{308}{500}

p = 0.616

2) A 90% confidence interval has z-score that is 1.645.

3) Calculate margin of error

ME=\sqrt{\frac{p(1-p)}{n} }

where

n is the sample size

So

ME=\sqrt{\frac{0.616(1-0.616)}{500} }

ME=\sqrt{\frac{0.616(0.384)}{500} }

ME = 0.02175

Then the interval is given by

p ± z(ME)

0.62 ± 1.645(0.02175)

0.62 ± 0.035

The interval will be

0.585 < p < 0.655

What this means is that we are 90% confident that the true proportion of Katy Perry's Twitter female followers is between 0.585 and 0.655.

Which is the simplified form of the expression (StartFraction (x Superscript negative 3 Baseline) (y squared) Over (x Superscrip
Vlad [161]

Answer:

The simplified form of the expression is \frac{1}{x^{7} y^{4}}.

Step-by-step explanation:

The expression is:

\frac{x^{-3}\cdot y^{2}}{x^{4}\cdot y^{6}}

The division rule of exponents is:

a^{m}\div a^{n}=a^{m-n}

The negative exponent rule is:

a^{-m}=\frac{1}{a^{m}}

Simplify the expression as follows:

\frac{x^{-3}\cdot y^{2}}{x^{4}\cdot y^{6}}=[x^{-3-4}]\times [y^{2-6}]

         =x^{-7}\times y^{-4}\\\\=\frac{1}{x^{7} y^{4}}

Thus, the simplified form of the expression is \frac{1}{x^{7} y^{4}}.
