You roll a fair 6-sided die what is p (not 3)

As a fraction, the exact answer is 5/6
In decimal form, the approximate answer is 0.8333

To get this answer, note how there are 5 ways to roll something that isn't a three (1,2,4,5,6) out of 6 ways total (1,2,3,4,5,6)

So you simply divide the two values to get 5/6 = 0.8333

Answer:

A sample size of 385 is needed.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1 - 0.95}{2} = 0.025$

Now, we have to find z in the Ztable as such z has a pvalue of $1 - \alpha$ .

That is z with a pvalue of $1 - 0.025 = 0.975$ , so Z = 1.96.

Now, find the margin of error M as such

$M = z\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

You feel that a reasonable estimate of the standard deviation is 10.0 hours.

This means that $\sigma = 10$

What sample size is needed so that the expected margin of error of your estimate is not larger than one hour for 95% confidence?

A sample size of n is needed. n is found when M = 1. So

$M = z\frac{\sigma}{\sqrt{n}}$

$1 = 1.96\frac{10}{\sqrt{n}}$

$\sqrt{n} = 1.96*10$

$(\sqrt{n})^2 = (1.96*10)^2$

$n = 384.16$

Rounding up:

A sample size of 385 is needed.

Determine whether each function is linear or quadratic. Identify the quadratic, linear, and constant terms. g(x)=-2 x²-3(x-2)

valentinak56 [21]

The function g(x) is a quadratic function:

Its quadratic term is -2x²
Its linear term is - 3x
Its constant is 6

<h3>What are functions?</h3>

Functions are algebraic expressions that have at least two variables, in order to make their visual representation through a graph and evaluate their behavior.

This problem deals with linear or quadratic functions, and these differ in the degree of the exponent of the variable:

1 : linear

2 : quadratic

The function:

g(x) = -2x² - 3(x- 2).

g(x) = -2x² - 3x + 6 , we have a quadratic function.

Its quadratic term is -2x²
Its linear term is - 3x
Its constant is 6
