Answer:
The probability is 52/83
Step-by-step explanation:
In this question, we are tasked with calculating the probability of having a student who is a sophomore or a student that wears glasses.
To do this, what we do is to first calculate the probability of having a student that is a sophomore, then calculate the probability of having a student wearing glasses. Now, considering the linking word or between the two cases, wherever we have or in probability, we are to add.
Firstly , let’s calculate the number of students we have = 6 + 13 + 5 + 27 + 9 + 23 = 83 students
The total number of sophomores we have is 5 + 27 = 32
Thus, the probability of having a sophomore is 32/83
The second case is that if a student that wears glasses. The total number of student wearing glasses is 6 + 5 + 9 = 20 students
The probability of finding a student wearing glasses is thus 20/83
Now, the probability of finding a student who wears glass or is a sophomore is 20/83 + 32/83 = 52/83
The segments above the bisector are proportional to the corresponding segments below.
(4x +1)/5 = 15/3
4x +1 = 25
x = (25 -1)/4 = 6
The value of x is 6.
Answer:
14 years
Step-by-step explanation:
To find the answer, you have to use the formula to calculate the time period:
t=(1/r)*(A/P-1), where:
t= time period
r= rate of interest=5%
A= accrued amount=$8,500
P= principal amount=$5,000
Now, you can replace the values in the formula:
t=(1/0.05)*(8,500/5,000-1)
t=20*0.7
t=14
According to this, the answer is that the money has been 14 years in the account.
