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
S=((294+3)*(294/3))/2=14553
Answer:
your answer is C.
Step-by-step explanation:
3x/5-0.5 = 1.9
+0.5 +0.5
————————
3x/5 = 2.4
x5 x5
___________
3x = 12
x = 4
Answer:
(-4,18)
Step-by-step explanation:
First, plug in -4 for x in the equation to solve for y, y = -2*-4+10, y = 8+10, y = 18. Now, you have the x and y coordinate for the point (-4,18).
