Answer: C. The measures of variation reveal nothing about the pattern over time.
Step-by-step explanation:
Given the following :
10 17 10 16 11 3 8 5 4 4 17 5 8 17
Range of hurricane data = 16
The standard deviation of sample data = 5.5 hurricanes
The variance of the sample data is 30.3 hurricane^2.
The measures of variation described above only shows the spread of the hurricane such as the range, that is the highest and lowest recorded.
The variance explains how spread out the data is and the standard deviation explains how values of a data differs from the mean value. The data fails to give time related information or pattern.
Answer:
x=
80-27
Step-by-step explanation:
there is needed atleast 80 tickets and you've given 27 so you would need a minimum of 53 tickets to make the inequilaty true
Answer:
1. 6pi or 18.84cm
2. 20pi or 62.8cm
3. 13pi or 40.82cm
4. 9.5pi or 29.83cm
5. You calculate the circumference of a circle with the expression 2pi(r). r stands for the radius. You can also use pi(d), or pi x diameter.
7. You would use 2pi(r) to find the circumference of a circle when given the value of the circle's radius.
8. You would use pi(d) to find the circumference of a circle when given the value of the circle's diameter.
Answer:
giyi
Step-by-step explanation:
8/15 = 56/105
This may be solved using proportion.
a/b = c/d
ad = bc where cross products are equal.
a = 8
b = f
c = 56
d = 105
ad = bc
8*105 = f*56
840 = 56f
840/56 = 56f/56
f = 15
56 ÷ 7 = 8
105 ÷ 7 = 15
