Answer:
Step-by-step explanation:
Standard form is basically where the degrees of the terms are in descending order.
First, let's distribute the negative sign to the terms in the second parentheses:
Now, we can just combine like terms with the terms from the first parentheses:
So, our answer is:
<em>Answer:</em>
<em>18</em>
<em>Step-by-step explanation:</em>
<em>Hi there !</em>
2² x 3³ x 4⁵/ 2 x 3 x 4⁵ =
<em>simplify 2 ; 3 ; 4⁵</em>
<em>= 2ₓ3²/1</em>
<em>= 2ₓ9</em>
<em>= 18</em>
<em>Good luck !</em>
Using the Empirical Rule, it is found that standard deviation of the sample proportions is of 0.058.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
0.684 and 0.916 is within 2 standard deviations of the mean(below and above), hence there are 4 standard deviations between these measures, so:
4s = (0.916 - 0.684)
s = (0.916 - 0.684)/4
s = 0.058.
