The standard deviation is 1.43 below the mean
<h3>How to determine the number of standard deviation?</h3>
The given parameters are:
Mean = 98.249
Standard deviation = 0.733
x = 97.2
To calculate the number of standard deviation below the mean, we use

So, we have:

Evaluate the like terms

Divide both sides by -0.733
n =1.43
Hence, the standard deviation is 1.43 below the mean

X^2+5x+6=0
(x+3)(x+2)=0
x-3, x-2
The given function is f(x)=2x^3+2x^2-x. In this case, the highest degree among the terms is 3. According to the Fundamental Theorem of Algebra, the number of zeros or roots of the equation is equal to the highest degree among the terms. Hence for every value of y, there are 3 equivalent x's. The answer thus is B. It is a many-to-one function.
It is answer D does that help?
I'll give you a pdf so you can see it yourself and the correct answer is -32b - 32b
