Which is greater? 79.47mi,54.28mi,65.5mi,98.43mi

Blababa [14]

Answer:

The greater value of the given set is 98.43.

Explanation:

Here the units of the distance given for all the data is miles(mi).

So, the greater value is that value which has higher magnitude.

Values are 79.47,54.28,65.5 and 98.43

Values in their increasing order is given by

54.28 < 65.5 < 79.47 < 98.43

Values in their decreasing order is given by

98.43 > 79.47 > 65.5 > 54.28

So, the greater value of the given set is 98.43.

$\textsf{Mean}\:\overline{X}=\sf \dfrac{\textsf{sum of all the data values}}{\textsf{total number of data values}}$

$\implies \sf Mean\:(Nilo)=\dfrac{5+6+14+15}{4}=\dfrac{40}{4}=10$

$\implies \sf Mean\:(Lisa)=\dfrac{8+9+11+12}{4}=\dfrac{40}{4}=10$

<h3><u>Standard Deviation</u></h3>

$\displaystyle \textsf{Standard Deviation }s=\sqrt{\dfrac{\sum X^2-\dfrac{(\sum X)^2}{n}}{n-1}}$

$\begin{aligned}\displaystyle \textsf{Standard Deviation (Nilo)} & =\sqrt{\dfrac{(5^2+6^2+14^2+15^2)-\dfrac{(5+6+14+15)^2}{4}}{4-1}}\\\\& = \sqrt{\dfrac{482-\dfrac{40^2}{4}}{3}}\\\\& = \sqrt{\dfrac{82}{3}}\\\\& = 5.23\end{aligned}$

$\begin{aligned}\displaystyle \textsf{Standard Deviation (Lisa)} & =\sqrt{\dfrac{(8^2+9^2+11^2+12^2)-\dfrac{(8+9+11+12)^2}{4}}{4-1}}\\\\& = \sqrt{\dfrac{410-\dfrac{40^2}{4}}{3}}\\\\& = \sqrt{\dfrac{10}{3}}\\\\& = 1.83\end{aligned}$

<h3><u>Summary</u></h3>

Nilo has a mean score of 10 and a standard deviation of 5.23.

Lisa has a mean score of 10 and a standard deviation of 1.83.

The <u>mean</u> scores are the <u>same</u>.

Nilo's standard deviation is higher than Lisa's. Therefore, Nilo's test scores are more <u>spread out</u> that Lisa's, which means Lisa's test scores are more <u>consistent</u>.

How do you solve 5(3x+7) =3 (5x+7) ?

Naya [18.7K]

5(3x+7)=3(5x+7)

15x+35=15x+21

cancel out the 15x. If you bring over one of the 15x it's going to naturally cancel each other out.

35=21

35 does not equal 21

it would be the equal sign with the slash coming through it
