First, multiply 20 x 25 to find the amount of chairs per section:
20 x 25 = 500
Now, multiply 500 x 4 to find the total amount of chairs for 4 sections:
500 x 4 = 2000
Hope this helps!! :)
Answer:
12.25%.
explanation :
I add 8.25% and 4 since you are trying to find the interest of his account earn after 4 years. 8.25 + 4= 12.25. Yea so that is how I get my answer.
All the probabilities are given for the three different scenarios in men and women: people who smoke, people who develop lung cancer, and people who develop lung cancer who are also smokers. Then, these are even classified in terms of gender.
But the final question only has to do with men who are smokers that develop lung cancer. So, I think all the other data are only there for the purpose of red herring. The answer is already there, but you just have to find it among the others. First, you ignore all the probabilities involving women because we only want the men. Then, you find the probability of men that have lung cancer being smokers. The answer is 90%.
1/8 * 32 = 4mph that is the correct answer
Answer: 120 students
Explanation:
Let x be the number of scopes
Let a be the number of student at school
1x = 5 students
But 5x = a
1x = 4 students
But the principal needs 6 additional scope so that all the students can use it.
=> (x + 6) = 4 students
=> 4(x + 6) = a
Thus,
5x = 4(x + 6)
5x = 4x + 24
5x - 4x = 24
x = 24
So, there are 24 scopes.
Plug x in both equation and compare:
5x = a
5(24) = a
120 = a
4(x + 6) = a
4(24 + 6) = a
4(30) = a
120 = a
Therefore, the students at the school are 120
