Answer:
<h2>The mean is 26666.67 and the standard deviation is 372919430.33.</h2>Step-by-step explanation:
The mean means the average of the numbers.
The mean will be .
The differences of the earnings from the mean are 1666.67, 26997.33, 33997.33.
Squaring the numbers we get, 2777788.89, 728855827.13, 1155818447.12.
We need to find the mean of the above numbers to get the standard deviation.
Thus, the standard deviation is .
Answer:
Choice A) a² - 9a - 11.
Step-by-step explanation:
Separate the terms by the power of the variable, .
Terms with power 2 on :
- First equation: 6a²;
- Second equation: -5a².
Terms with power 1 on :
- First equation: -17a;
- Second equation: 8a.
Terms with power 0 on , which are also known as constant terms:
- First equation:
;
- Second equation:
.
Apply the distributive property of multiplication in reverse. In other words, factor out terms with the same power and add the coefficients.
Terms with power 2 on :
