The variance of a distribution is the square of the standard deviation
The variance of the data is 2.2
<h3>How to calculate the variance</h3>
Start by calculating the expected value using:
So, we have:
This gives
Next, calculate E(x^2) using:
So, we have:
The variance is then calculated as:
So, we have:
Approximate
Hence, the variance of the data is 2.2

Sorry if I am wrong
Answer: 6.164 √38
Step-by-step explanation: hope this is what your looking for :)
Perform the indicated division, if any.
Rate: (500 miles)/(20 hours)
Unit rate: (500/20) miles/hour = (25 miles)/(1 hour) = 25 miles/hour
A unit rate is a rate with one unit in the denominator.
Answer:
4
Step-by-step explanation:
f(x) (8x² - 3x + 1) / (2x² + 2x +3)
the first thing I did was to graph the function to see if there was a horizonal asymptote using Desmos graphing calculator and there was and it was 4
you want to take the limit as x approaches infinity
essentially lim(x to ∞) of f(x) = 8x²/ 2x² is the dominate terms
lim(x to ∞) of f(x) = 8 / 2
lim(x to ∞) of f(x) = 4
