Pamela called nine repair shops for quotes for auto repairs. The prices are $139, $150, $345, $99, $167, $155, $140, $200, and $

160. She thinks there is a chance that there is an outlier and the data may be biased. Which measure of central tendency should she choose and what value would best represent the central tendency?

Answer:

Step-by-step explanation:

The prices of quoted of auto repairs are as listed below;

$139, $150, $345, $99, $167, $155, $140, $200.

For her to check whether there is an outlier in the data, she needs to find the mean of the set of data. An outlier is a value in a set of a data that varies considerably from other data in a dataset. It may be larger or smaller than other set of datas. An outlier can affect the decision of a set of data to be analysed if nor taken care of.

From the data, the possible outliers are $99 and $345

Mean of the data = sum of all the prices/sample size

xbar = \sum Xi / N

Xi are individual datas

\sum Xi = $139+$150+$345+$99+$167+$155+$140+$200+$160

\sumXi = $1555

Sample size = 9

Mean = $1555/9

Mean = $172.78

Hence the value that would best represent the central tendency is $177.78

What is the distance between coordinates (-6.25,5) and (-3.75,2)
Oksi-84 [34.3K]

Answer:

\sqrt{15.25}

Step-by-step explanation:

To find the distance, we can use the distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} when the given points are (x_1,y_1) and (x_2,y_2)

Plug in the points (-6.25,5) and (-3.75,2)

d=\sqrt{(-6.25-x_1)^2+(5-y_1)^2}\\d=\sqrt{(-6.25-(-3.75))^2+(5-2)^2}\\d=\sqrt{(-6.25+3.75)^2+(5-2)^2}\\d=\sqrt{(-2.5)^2+(3)^2}\\d=\sqrt{6.25+9}\\d=\sqrt{15.25}

Therefore, the distance between the two coordinates is \sqrt{15.25}, or approximately 3.91.

I hope this helps!

If the each side of equalaterial triangle is a cm. what is the area?​
Yuri [45]

Step-by-step explanation:

area \: of \: a \: triangle =  \frac{1}{2}  \times base \times height \\  \\ base =  \frac{a}{2} cm \\  {h}^{2}  +   {( \frac{a}{2} )}^{2}  =  {a}^{2}  \\  \\ h =  \sqrt{ {a}^{2} -  \frac{ {a}^{2} }{4}  }  \\  \\ area \: of \: triangle =  \frac{1}{2}  \times b \times h \\  =  \frac{1}{2}  \times  \frac{a}{2}  \times  \sqrt{ {a}^{2}  -  \frac{ {a}^{2} }{4} }  \\  \\  =  \frac{a}{4}  \times  \sqrt{ {a}^{2} -  \frac{ {a}^{2} }{4}  }
