Answer:
a) =4.63 md=4.55 mo= 1.9 b) Sample Standard Deviation≈ 2.58 Coefficient of Variation=55.72% Sample Range=6.9
Step-by-step explanation:
a)
<u>Mean</u>
For the <u>Median</u>, we have to order the entries. So, ordering it goes:
1.9 1.9 2.3 3.9 5.2 5.7 7.3 8.8
Since we have even entries
mode
The mode for this data 1.9 1.9 2.3 3.9 5.2 5.7 7.3 8.8 is 1.9
b)
<u>Sample Standard Deviation</u>
Here it is the formula to calculate it:
<u>Coefficient of Variation</u>
CV is the quocient between sample Standard deviation over Mean and it is used to make comparisons.
<u>Range</u>
The difference between the highest and the lowest value of this sample
8.8-1.9=6.9
Answer: Length = x² - 6x - 16
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as. Area = length × width
Length = Area/width
The area of a rectangle is represented by the function
x³ - 2x² - 40x - 64. The width of the rectangle is x + 4. Therefore,
Length = (x³ - 2x² - 40x - 64)/(x + 4)
We would apply the method of long division. The steps are shown in the attached photo. From the photo,
Length = x² - 6x - 16
