The value of the expression 4(5² - 3 - 2x)² is 576.

In the question, we are asked to evaluate the expression 4(5² - 3 - 2x)², where x = 5.

To find the value of the expression, we find the value of each term with the value assigned to the variable and then put back the terms in the expression to get the final value.

The term 5² = 25.

The term 2x, when x = 5, can be shown as 2x = 2*5 = 10.

Taking the terms back to the expression, we get:

4(5² - 3 - 2x)²

= 4(25 - 3 - 10)²

= 4(12)²

= 4(144)

= 576.

Thus, the value of the expression 4(5² - 3 - 2x)² is 576.

Are the fractions 1/5 , 5/5 , and 5/1 equivalent?Explain.

NeX [460]

Answer:
They are not equal

Explanation:
Let's take a look at each one of them separately:
 $\frac{1}{5}$ : This fraction is in the simplest form. It is equivalent to 0.2
The fraction is formed by dividing one part over five

 $\frac{5}{5}$ : This fraction is not in the simplest form. We can divide 5 by 5 and the answer would be 1. Therefore, $\frac{5}{5}$ is equivalent to 1

 $\frac{5}{1}$ : This fraction is not in the simplest form. We can divide 5 by 1 and the answer would be 5. Therefore, $\frac{5}{1}$ is equivalent to 5.

Based on the above, we can cnfirm that 0.2 , 1 and 5 are not equivalent.
Therefore, the given fractions are not equivalent

Hope this helps :)

<h3>What is the margin of error(MOE)?</h3>

It is defined as an error that provides an estimate of the percentage of errors in real statistical data.

The formula for finding the MOE:

$\rm MOE = Z\times \dfrac{s}{\sqrt{n}}$

Where Z is the z-score at the confidence interval

s is the standard deviation

n is the number of samples.

At 99% confidence Z = 2.576

By using the MOE formula:

0.05 = 2.376×√(0.5(0.5)/n)

After calculating

n = 663.57 ≈ 664

Thus, the sample size suggested by this statement is 664 option second is correct.
