Since both 4 and 6 are divisible by 2, it becomes 2/3<span />
Answer:
3
Step-by-step explanation:
because 3x3= 9 and 4x3=12 and 5x3=15
Answer:
8 classes
Step-by-step explanation:
Given
![Least = 2403](https://tex.z-dn.net/?f=Least%20%3D%202403)
![Highest = 11998](https://tex.z-dn.net/?f=Highest%20%3D%2011998)
![n = 225](https://tex.z-dn.net/?f=n%20%3D%20225)
Required
The number of class
To calculate the number of class, the following must be true
![2^k > n](https://tex.z-dn.net/?f=2%5Ek%20%3E%20n)
Where k is the number of classes
So, we have:
![2^k > 225](https://tex.z-dn.net/?f=2%5Ek%20%3E%20225)
Take logarithm of both sides
![\log(2^k) > \log(225)](https://tex.z-dn.net/?f=%5Clog%282%5Ek%29%20%3E%20%5Clog%28225%29)
Apply law of logarithm
![k\log(2) > \log(225)](https://tex.z-dn.net/?f=k%5Clog%282%29%20%3E%20%5Clog%28225%29)
Divide both sides by log(2)
![k > \frac{\log(225)}{\log(2)}](https://tex.z-dn.net/?f=k%20%3E%20%5Cfrac%7B%5Clog%28225%29%7D%7B%5Clog%282%29%7D)
![k > 7.8](https://tex.z-dn.net/?f=k%20%3E%207.8)
Round up to get the least number of classes
![k = 8](https://tex.z-dn.net/?f=k%20%3D%208)
Answer:
2 min
Step-by-step explanation:
she runs 5 miles in 52 min
her goal is 6 miles
so if 5 miles is completed in 50 min then 1 mile = 10 min
and 6 mile = 60 min
