How many parallelograms are in an octagonal prism?

Snezhnost [94]

Answer:

In this way, two hexagons and a parallelogram with five inner lines are obtained. Each hexagon has six edges, therefore the prism will have more than 12 edges. At first glance, it is thought that the parallelogram contains nine edges (seven vertical and two horizontal).

In 2008, the average household debt service ratio for homeowners was 13.2. The household debt service ratio is the ratio of debt

ankoles [38]

Answer:

$t=\frac{13.88-13.2}{\frac{3.14}{\sqrt{44}}}=1.436$

$df=n-1=44-1=43$

$p_v =P(t_{(43)}>1.436)=0.079$

We see that the p value i higher than the significance level so then we FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly higher than 13.2 *the value of 2008 ).

Step-by-step explanation:

Information given

$\bar X=13.88$ represent the sample mean

$s=3.14$ represent the sample standard deviation

$n=44$ sample size

$\mu_o =13.2$ represent the value that we want to test

$\alpha=0.05$ represent the significance level

t would represent the statistic (variable of interest)

$p_v$ represent the p value for the test

Hypothesis to test

We want to conduct a hypothesis in order to check if the true mean has increased from 2008 , and the system of hypothesi are:

Null hypothesis: $\mu \leq 13.2$

Alternative hypothesis: $\mu > 13.2$

The statistic for this case is:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

Calculating the statistic

Replacing the info given we got:

$t=\frac{13.88-13.2}{\frac{3.14}{\sqrt{44}}}=1.436$

P-value

The degrees of freedom are:

$df=n-1=44-1=43$

Since is a right tailed test the p value is:

$p_v =P(t_{(43)}>1.436)=0.079$

Decision

We see that the p value i higher than the significance level so then we FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly higher than 13.2 *the value of 2008 ).

Please help will vote brainliest

IgorLugansk [536]

Answer:

653.45 cm^2

Step-by-step explanation:

The volume of a cylinder can be found using:

v=pi r^2 h

We know the radius is 4, and the height is 13, so we can substitute them in

v=pi (4^2)(13)

v=pi (16)(13)

v=pi 208

v=653.451272

Rounded to the nearest hundredth

v=653.45

So the volume is 653.45 cm^3

Can someone pls help me out? im begging you

aniked [119]

Answer:

42

Step-by-step explanation:

The whole thing is 360 degrees. To me, it looks like the angles in the middle are divided in to 4 equal parts. 360/4=90. Now set the equation equal to 90. 90-6=84, and 84/2=42.

Answer:

1. Points scored

Step-by-step explanation:

A numerical data is defined as a data that is made up of numbers representing the quantity of a measurement. It is a measurable data such as weight or height, at it can be arranged in ascending or descending order as well as being able to provide an average.

The two types of numeric data are discrete and continuous data

A categorical data is made up of item labels, names or description, that are qualitative in their nature.

Information about a football team that is considered as numeric includes

1. Points scored

Which represents a quantifiable measurement that can be different with different teams and matches

2. Attendance this year.
