Answer:
18 because it all the kids can fit in all the vans
Answer:
Range = 29
Variance= (X₁- U) ² / N= 973/10 = 97.3
Standard Deviation= √variance= √97.3= 9.864
Step-by-step explanation:
Range = Difference between the highest and lowest value = 97-68= 29
Variance
X₁ X₁-U (X₁- U) ²
80 0 zero
68 -12 144
71 -9 81
72 -8 64
95 15 225
89 9 81
97 17 289
72 -8 64
75 -5 25
81 1 1
∑ 800 ZERO 973
u= ∑X₁ /10=800/10=80
Variance= (X₁- U) ² / N= 973/10 = 97.3
Standard Deviation= √variance= √97.3= 9.864
(b) The important feature of the data is not revealed through the different measures of variation is that the variability of two or more than two sets of data cannot be compared unless a relative measure of dispersion is used .
The length of rectangle is 15 feet and width is 7 feet.
Step-by-step explanation:
Given,
Width of rectangle = w
Length of rectangle = 2w+1
Perimeter = 44 feet
Perimeter = 2(Length+Width)

Dividing both sides by 6

The width of rectangle is 7 feet.
Length of rectangle = 2(7)+1 = 14+1 = 15 feet
The length of rectangle is 15 feet and width is 7 feet.
