Complete the paragraph below. The standard deviation is used in conjunction with the ______ to numerically describe distributio

Bumek [7]

Answer:

The standard deviation is used in conjunction with the mean to numerically describe distributions that are bell shaped. The mean measures the center of the distribution, while the standard deviation measures the spread of the distribution.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by

$Z = \frac{X - \mu}{\sigma}$

The mean is the average value of the measures while the standard deviation measures how spread the measures are from the mean. So

The standard deviation is used in conjunction with the mean to numerically describe distributions that are bell shaped. The mean measures the center of the distribution, while the standard deviation measures the spread of the distribution.

Simplify the expression.

denis23 [38]

Answer:

option d

Step-by-step explanation:

$\sf \boxed{a^m*a^n = a^{m+n}\\\\}$

$\sf \left(\frac{m^{-1}m^{5}}{m^{-2}} \right)^{-3} =\left(\dfrac{m^{-1+5}}{m^{-2}}\right)^{-3}$

$\sf = \left(\dfrac{m^4}{m^{-2}}\right)^{-3}\\\\$

$\boxed{\dfrac{a^{m}}{a^{n}}=a^{m+n}}$

$\sf = \left(m^{4-[-2]}\right)^{-3}\\\\ =\left(m^{4+2}\right)^{-3}\\\\ = \left(m^6\right)^{-3}\\\\$

$\boxed{(a^{m})^n=a^{m*n}}$

$\sf= m^{6*(-3)}\\\\ = m^{-18}$

$\boxed{a^{-m}=\dfrac{1}{a^m}}$

$\sf=\dfrac{1}{m^{18}}$

trapecia [35]

Answer:

6.25

Step-by-step explanation:

$(-2\frac{1}{2})^2\\\\(-\frac{5}{2} )^2\\\\(\frac{5}{2})^2\\\\\frac{5^2}{2^2}\\\\\frac{25}{4}\\\\\boxed{6\frac{1}{4}}\text{ or } 6.25$

Hope this helps.

In a recent survey of 974 voters, 724 indicated that they were in favor of a new city park, while the other 250 voters said that

Lesechka [4]

10, 267

the fraction of voters opposed from the survey = $\frac{250}{974}$

Assuming this fraction as a basis then the predicted number against will be

40, 000 × $\frac{250}{974}$ = 10, 267 ( nearest while number )
