Answer:
see explanation
Step-by-step explanation:
The degree of a polynomial is determined by the value of the largest exponent of the variable.
Given
4x + 2x³
The largest exponent is 3, thus the polynomial is of degree 3
A polynomial of degree 3 is called a cubic
The numbers -8 and -1 can do that.

Answer:
3.6
Step-by-step explanation:
The standard deviation of the data set is 19.3
<h3>How to find the standard deviation of the data set?</h3>
The dataset is given as:
82, 94, 105, 68, 57
Calculate the mean using
Mean = Sum/Count
So, we have
Mean = (82 + 94 + 105 + 68 + 57)/5
Evaluate
Mean = 81.2
The standard deviation is then calculated as:
![\sigma = \sqrt{\frac{\sum (x - \bar x)^2}{n-1}}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B%5Cfrac%7B%5Csum%20%28x%20-%20%5Cbar%20x%29%5E2%7D%7Bn-1%7D%7D)
So, we have:
SD = √[(82 - 81.2)^2 + (94 - 81.2)^2 + (105 - 81.2)^2 + (68 - 81.2)^2 + (57 - 81.2)^2)/5 - 1]
This gives:
SD = √[1490.8/4]
So, we have:
SD = 19.3
Hence, the standard deviation of the data set is 19.3
