X^4 - 4x^3 - 9x^2 + 36x = 0
x(x^3 - 4x^2 - 9x + 36) = 0
x(x^2(x - 4) - 9(x - 4) = 0
x(x + 3)(x - 3)(x - 4) = 0
the zeroes are -3, 0, 3, 4 Answer
Answer:
The mean is 39
The median is 42
Step-by-step explanation:
The median is the best measure of center for the above data because half of the values are less than the median and half of the values are more than the median. It's probably the best measure of center to use in a skewed distribution.
The measure of variability is the range because is the simplest measure of variability to calculate but can be misleading if the dataset contains extreme values.
The variability is 67.25
This is how I did it
Hi there!
<u><em>Answer:</em></u>
<u><em>t=26</em></u>
<u><em>*The answer must have a positive sign.*</em></u>
Step-by-step explanation:
First, you subtract by 19 from both sides of an equation.

Then, you subtract by the numbers from left too right.

<u><em>Final answer is t=26</em></u>
I hope this helps you!
Have a nice day! :)
