Solution: We have to find the Frequency and Relative frequency of the given data:
Frequency is the number of times a number occurs.
Relative Frequency is the number of times a number occurs divided by the total number of items.
Therefore, the frequency and relative frequency are calculated as below:
Number Frequency Relative Frequency
20 1 
21 4 
22 2 
23 4
24 3 
25 2 
26 3 
27 5 
28 3 
29 4 
Total 31
Ok so what you need to do is first find the area of the circle using π r^2. So π12^2 or π144= 452.389342117 This is the area of the whole circle. To find the area of the sector you have to multiply the total area by 172/360 or 0.47777777777 This will get you 216.141574567 round as necessary but your answer is <span>216.141574567units^2</span>
Answer:
the perfect squares between 120 and 300 are the squares of numbers from 11 to 17. Clearly, these are 7 in number.
Step-by-step explanation:
Answer:
5.9km
Step-by-step explanation:
this would b solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
1.2² + 5.8² = c²
1.44 + 33.64 = c²
35.08 = c²
c = 5.9 km
60 ÷ 15 = 4
4÷4=1
so your answer is 1 mile.
