Answer:

C. the probability of it not happening is 0.3.

Step-by-step explanation:

Probability of event happening is of 0.7.

Either it happens, or it does not. The sum of these probabilities is 100%.

0.7 probability of happening, so 1 - 0.7 = 0.3 probability of not happening, and the correct answer is given by option C.

A is wrong as the probability is not 1, and B is wrong as the probability is higher than 0.5.

Which is a stretch of an exponential decay function? f(x) = one-fifth (one-fifth) superscript x f(x) = one-fifth(5)x f(x) = 5one

vitfil [10]

The exponential function that represents a stretch of a decay function is given as follows:

$f(x) = \frac{5}{4}\left(\frac{4}{5}\right)^x$

<h3>What is an exponential function?</h3>

An exponential function is modeled by:

$y = ab^x$ .

In which:

a is the initial value.

b is the rate of change.

It represents a stretch if a > 1, and a decay function if b < 1. Researching the problem on the internet, the correct option is given as follows:

$f(x) = \frac{5}{4}\left(\frac{4}{5}\right)^x$

Write the standard form of the simplest polynomial with the roots 2, 3, and -3

koban [17]

$\text{If}\ x_1,\ x_2\ \text{and}\ x_3\ \text{are roots of a polynomial, then we can write that polynomial}\\\text{in form}\ (x-x_1)(x-x_2)(x-x_3).\\\\\text{We have\ the\ roots:}\ 2,\ 3\ \text{and}\ -3.\\\\w(x)=(x-2)(x-3)(x-(-3))=(x-2)\underbrace{(x-3)(x+3)}_{use\ a^2-b^2=(a-b)(a+b)}\\\\=(x-2)(x^2-9^2)=(x-2)(x^2-9)=(x)(x^2)+(x)(-9)+(-2)(x^2)+(-2)(-9)\\\\=x^3-9x-2x^2+18=\boxed{x^3-2x^2-9x+18}$
