The average weight of a bar of soap should be 6.4 ounces with a standard deviation of 0.2 ounces. A sample of 20 bars of soap fo

-Dominant- [34]

Answer:

The testing statistic is -2.237

Step-by-step explanation:

Test statistic (z) = (sample mean - population mean) ÷ (population standard deviation/√n)

sample mean = 6.3 ounces

population mean = 6.4 ounces

population standard deviation = 0.2 ounces

n (sample size) = 20

z = (6.3 - 6.4) ÷ (0.2/√20) = -0.1 ÷ 0.0447 = -2.237

In your own words, explain the Normal Distribution and provide a real world example.

elena-14-01-66 [18.8K]

Answer:

The Normal distribution is a continuous probability distribution with possible values all the reals. Some properties of this distribution are:

Is symmetrical and bell shaped no matter the parameters used. Usually if X is a random variable normally distributed we write this like that:

$X \sim N(\mu , \sigma)$

The two parameters are:

$\mu$ who represent the mean and is on the center of the distribution

$\sigma$ who represent the standard deviation

One particular case is the normal standard distribution denoted by:

$Z \sim N(0,1)$

Example: Usually this distribution is used to model almost all the practical things in the life one of the examples is when we can model the scores of a test. Usually the distribution for this variable is normally distributed and we can find quantiles and probabilities associated

Which system of equations can you use to find the roots of the equation 2x3 + 4x2 – x + 5 = –3x2 + 4x + 9?

Degger [83]

Answer:

$y=2x^3+4x^2-x+5$

$y=-3x^2+4x+9$

Step-by-step explanation:

The given equation is in the form $2x^3+4x^2-x+5=-3x^2+4x+9$

We have to evaluate the correct system of equations which can be used to find the roots of the equation.

We can find the root of the equation by plotting the graph of the equations. In order to graph, we can assume the left and right hand side of the given equation as two separate equations.

Therefore, we have

$y=2x^3+4x^2-x+5$

$y=-3x^2+4x+9$

Now, we plot the graph of these two equations in the same coordinate plane. The intersection point (s) would be the roots of the given equation.

Hence, the system of equation that we can use to find the root of the given equation is

$y=2x^3+4x^2-x+5$

$y=-3x^2+4x+9$

Last option is correct.
