Write a power represented with a positive base and a positive exponent whose value is less than the base

Murrr4er [49]

That's always true if either the exponent or the base is less than ' 1 '.

(But not always of they both are.)

5#The distribution of scores on a standardized aptitude test is approximately normal with a mean of 480 and a standard deviation

kirza4 [7]

We want to find the value that makes

$P(X\ge x)=0.2$

To find it we must look at the standard normal table, using the complementary cumulative table we find that

$P(Z\ge z)=0.20045\Leftrightarrow z=0.84$

Then, using the z-score we can find the minimum score needed, remember that

$z=\frac{x-\mu}{\sigma}$

Where

σ = standard deviation

μ = mean

And in our example, x = minimum score needed, therefore

$\begin{gathered} 0.84=\frac{x-480}{105} \\ \\ x=0.84\cdot105+480 \\ \\ x=568.2 \end{gathered}$

Rounding to the nearest integer the minimum score needed is 568, if you get 568 you are at the top 20.1%.

Answer:

Hi, There! Mika-Chan I'm here to help! :)

First We Need to know If we're rounding to the Nearest Hundred thousand or Not.

So The Answer would Be 800,000 If your Going to Round to the nearest Hundred

But If We're rounding to The Nearest ten Thousand The Answer would be 830,000

:D hope this Helps you!
