Answer:
24;120;201600
Step-by-step explanation:
25. 3 salads, 4 main courses, 2 vegetables, 1 dessert
3*4*2*1=24
26. 5*4*3*2*1=120
27. 8*7*6*5*5*4*3*2*1= 201600
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:
021110321....1.12...1.1.631.6301
Step-by-step explanation:
<h3>I'll teach you how to solve 11X - X2 +4y2 = 52</h3>
-----------------------------------------------------------
11X - X2 +4y2 = 52
Add similar elements:
9x+4*2y= 52
Multiply the numbers 4*2:
4*2= 8
9x+8y= 52
Subtract 8y from both sides:
9x+8y-8y= 52- 8y
Simplify:
9x= 52- 8y
Divide both sides by 9:
9x/9= 52/9 - 8y/9
Simplify:
x=
