F=p(1+rt)
6200=5000(1+6r) divided both sides by 5000
1.24=1+6r
1.24-1=6r
6r=0.24
R=0.04*100=4%
Is it this problem if it is i can help you if not please provide a questions and the data.
First you want to isolate the variable, do this by adding 18 to both sides. You're left with 12r = 13r + 36, then subtract 13r to get the variables alone. You're then left with -1r = 36, multiply by -1 to remove the negative. The final result would be (1) r = 36.
Answer:
The number of ways in which students were chosen is 45 ways .
Step-by-step explanation:
Given as :
The number of students in a class = x = 10
The number of students chosen by teacher to go to library = y = 2
Let The number of ways in which students were chosen = n ways
<u>Now, According to question</u>
So, number of ways in which students were chosen = 
Or, n ways = 
Or, n = 
Or, n = 
Or, n = 
Or, n = 
Or, n = 5 × 9
i.e n = 45
So, The number of ways in which students were chosen = n = 45 ways
Hence,The number of ways in which students were chosen is 45 ways . Answer
