Answer:
a)
Mean = sum of all numbers in dataset / total number in dataset
Mean = 8130/15 = 542
Median:
The median is also the number that is halfway into the set.
For median, we need to sort the data and then find the middle number which in our case is 546. Below is the sorted data
486 516 523 523 529 534 538 546 548 551 552 558 566 574 586
Standard Deviation (SD). Here X represents dataset and N= count of numbers in data
As per the SD formula, which is Sqrt ( sum (X_i - Meanx(X))/(N-1))
SD= 25.082
2) Formula for coefficient of skewness using Pearson's method (using median) is,
SK = 3* ( Mean (X) - Median(X))/(Standard Deviation) = 3*(542-546)/25.082 = -0.325
3) coefficient of skewness using the software method is also same which is -0.325
Answer:
Step-by-step explanation:
1.68/6=0.28 per pencil in pack 1
2.34/9 =0.26 per pencil in pack 2
So pack 2 is better in terms of Maths
But in business, people prefer pack 1
I believe the trains speed average was about 34 km/h

<h3>What is the Circumcenter of Triangle?</h3>
Circumcenter is the point where all three perpendicular bisectors of the three sides of a triangle meet and they are of equal distance from the three vertices of the triangle.
- The line that contains the circumcenter in ΔABC is: <em>line k.</em>
<h3>What is the Orthocenter of a Triangle?</h3>
Orthocenter is the point in a triangle where the three altitudes that are perpendicular to the opposite sides and connect with the vertices of the triangle intersect.
- The line that contains the orthocenter in ΔABC is: <em>line m.</em>
<h3>What is the Centroid of a Triangle?</h3>
The centroid of a triangle is a the point of intersection where all three medians of a triangle. Medians of a triangle connects the vertices to the midpoints of the opposite sides of a triangle.
- The line that contains the centroid in ΔABC is: <em>line l.</em>
<h3>What is the Incenter of a Triangle?</h3>
The incenter of a triangle is the point in a triangle where all three angle bisectors of the vertices of a triangle.
- The line that contains the centroid in ΔABC is: <em>line n.</em>
