Answer:

A. $11\frac{5}{8}\textrm{ inches}$

Step-by-step explanation:

Given:

The regular polygon is a decagon having 10 sides.

Perimeter of the given polygon is,

$P=116\frac{1}{4}\textrm{ inches}=116.25\textrm{ inches}$ .

We know that, perimeter of a regular polygon of $n$ sides is given as,

$P=na$ where, $a$ is the length of each side.

Here, $n=10,P=116\frac{1}{4}\textrm{ in}$

Plug in these values and solve for $a$ . This gives,

$P=na\\116\frac{1}{4}=10a\\116.25=10a\\a=\frac{116.25}{10}=11.625=11+\frac{625}{1000}=11+\frac{5}{8}=11\frac{5}{8}\textrm{ in}$

Therefore, the side length of the given polygon is $11\frac{5}{8}\textrm{ inches}$

Find the P-value for the indicated hypothesis test with the given standardized test statistic, z. Decide whether to reject H0

Leviafan [203]

Answer: We do not reject the null hypothesis.

Step-by-step explanation:

When the p-value is greater than the significance level , then we do not reject the null hypothesis or if p-value is smaller than the significance level , then we reject the null hypothesis.

Given : Test statistic : $z = -2.28$

Significance level : $\alpha=0.02$

By using the standard normal distribution table ,

The p-value corresponds to the given test statistic ( two tailed ):-

$2P(Z>|z|)=2P(Z>2.28)=0.0226$

Since the p-value is greater than the significance level of 0.02.

Then , we do not reject the null hypothesis.

Plase help me I already set the equation up I just need you to solve it.

masya89 [10]

$\sf \frac{6}{30} = \frac{x}{100}$

Solve for x by cross multiplication

$\sf6 \times 100 = x \times 30$

Multiply the numbers

$\sf \: 600 = 30x$

Swap the sides of equation

$\sf \: 30x = 600$

Divide both sides of equation by 30

$\boxed{ \tt \: x = 20}$
