Answer: Option C.
Step-by-step explanation:
A function goes trough the x-axis when f(x) = 0 for some value of x.
For example, when we say that a quadratic function has no real zeros, this means that the determinant is less than zero, so the roots of the equation:
a*x^2 + b*x + c = 0
are complex roots, this means that for the function:
f(x) = y = a*x^2 + b*x + c
there is not a real number x such f(x) = 0
So the correct option is C.
Answer:
V=125
look it up and a wole procces does it and shows you how to do it. Just look up
"Cube solve (units)" and you can do voloume and stuff
First of all find the mean that is:
Mean = (1+2+3+4+5+6)/6 = 3.5
1) Draw a frequency distribution table as shown here below
X X - Mean (X-Mean)²
1 1-3.5 (-2.5)²
2 2-3.5 (-1.5)²
3 3-3.5 (-0.5)²
4 4-3.5 (0.5)²
5 5-3.5 (1.5)²
6 6-3.5 (2.5)²
--- ------- -------------
∑=21 ∑=0 ∑ = 17.5 Note than the number of classes is n= 6
Variance = σ² = 17.5/<span>6 = 2.917
</span>Standard deviation = √σ² = √2.917==> σ =1.708 (answer C)
