Well, first of all, all things with % mean over 100. So the question is represented as 225/100. And i am changing it to its simplest form. 
225/100=45/20
45/20=9/4
  So the fraction equivalent in its simplest form is 9/4. Hope i helped.
NOTE; I divided the fraction by 5

Answer:

The answer to your question is:

Step-by-step explanation:

   \frac{x^{2}-16 }{2x + 4} \frac{x^{3}-2x^{2} + x }{x^{2}+ 3x - 4}

Factorize    \frac{(x+4)(x-4)}{2(x+2)}  \frac{x(x^{2}-2x + 1) }{(x+4)(x-1)}

Factorize    \frac{(x+4)(x-4)}{2(x+2)} \frac{x(x-1)^{2} }{(x+4)(x-1)}

Simplify      \frac{x(x-4)}{2(x+2)}

When finding the margin of error for the mean of a normally distributed population from a sample, what is Alpha, assuming a conf
MArishka [77]

The value of alpha is 0.26, assuming a confidence level of 74%.

<h3>What is the margin of error?</h3>

The significance level α is the probability of making the wrong decision when the null hypothesis is true.

Alpha levels which is also called as significance levels are used in hypothesis tests.

Given

When finding the margin of error for the mean of a normally distributed population from a sample.

The confidence interval = 74% = 0.74.

The value of the alpha is given by;

\rm \alpha =1- Confidence \ interval

Substitute all the values in the formula

\rm \alpha =1- Confidence \ interval\\\\\alpha=1-0.74\\\\\alpha=0.26

Hence, the value of alpha is 0.26, assuming a confidence level of 74%.

Samantha is taking out a loan for $17,452 at 6% simple interest for one year. How much interest will she pay?
andrew11 [14]

Answer:

<em>She will pay $1,047.12 interest for one year</em>

Step-by-step explanation:

<u>Simple Interest</u>

Occurs when interest is calculated on the original principal only.

Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.

The interest earned is calculated as follows:

I=P.r.t

Where:

I = Interest

P = initial principal balance or loan

r = interest rate

t = time

Samantha takes out a loan for $17,452 at r=6%=0.06 simple interest for t=1 year. Calculating the interest:

I=\$17,452*0.06 *1

I = $1,047.12

She will pay $1,047.12 interest for one year
