<h3>Answer: True</h3>

We have A = 2 copies of "2" showing up out of B = 13 rolls total

A/B = 2/13 = 0.1538 is the experimental probability of rolling a 2

Compare this with 1/6 which is the theoretical probability of rolling a 2 (since there is one side labeled "2" out of 6 sides total)

1/6 = 0.167 approximately

Comparing 0.1538 with 0.167 is fairly close

or you could argue that 2/13 is close to 2/12 = 1/6

Dy/dxif y = 4x3 + 3x2 + 2

DIA [1.3K]

The function is

$\displaystyle{ y=4x^3+3x^2+2$ .

We recall that the derivative of each monomial $ax^b$ is $a\cdot b\cdot x^{b-1}$ , and the derivative of a constant (function) is 0.

According to this:

$\frac{d}{dx}(4x^3+3x^2+2)=4\cdot 3\cdot x^2 + 3\cdot 2\cdot x+0 =12x^2+6x$ .

Answer: $12x^2+6x$
