Total students: 80
We know that:
-business has 14 students
-education has 6 students
-undecided has x students
We need to find out x! So we can add 14 and 6 up and subtract it by 80 to figure out the amount of undecided students there are.
80-(14+6)=60
To find out the percentage, we divide the number of undecided students by the number of total students, and multiply it by 100.
60/80=30/40=0.75=0.75*100=75%
75% of the class is undecided for a major
Answer:
Step-by-step explanation:
Given
6 rolls of a die;
Required
Determine the possible sequence of rolls
From the question, we understand that there were three possible outcomes when the die was rolled;
The outcomes are either of the following faces: 1, 2 and 3
Total Number of rolls = 6
Possible number of outcomes = 3
The possible sequence of rolls is then calculated by dividing the factorial of the above parameters as follows;
Hence, there are 120 possible sequence.
Answer:
25 more boxes is needed
Step-by-step explanation:
12000 batteries require 50 boxes. Let's find the unit rate.
That is, how many batteries are in each box??
That's 12,000/50!
12,000/50 = 240 batteries per box
Now, to find how many boxes we would need for 18,000 batteries, we will have to divide the total (18000) by 240(number of batteries per box). That is:
18,000/240 = 75 boxes
We would need 75 boxes to pack 18,000 batteries.
We want "how many MORE boxes needed", so we will the excess:
75 - 50 = 25 more boxes is needed
