Answer: The required probability is 9.09%.
Step-by-step explanation: Given that a jar contains 6 blue, 4 red, and 2 green marbles.
We are to find the probability that three blue marbles are drawn with out replacement.
Total number of marbles = 6 + 4 + 2 = 12.
After drawing one blue marble, we are left with total 11 marbles. And after drawing the second blue marble, we are left with total 10 marbles.
Therefore, the probability of drawing three blue marbles without replacement is given by
Thus, the required probability is 9.09%.
Answer:
420
Step-by-step explanation:
Assuming this is the problem:
At a school, 147 students play at least one sport. This is 35% of the students at the school. How many students are at the school?
147/35 = x/100
35x=147*100
35x=14,700
x=420
36 + 18 = 54
(1) 18/54 = 1/3 = 33%
43 + 24 = 67
(2) 24/67 = 36%
I hope these are right
Answer:
C. 3
Step-by-step explanation:
Given expression is:
We know that the rules of exponents are used to solve these kind of questions.
When there is exponent on exponent like in this question 1/7 has an exponent of 7 , the exponents are multiplied.
So,
The 7's will be cancelled out and remaining power will be 1
Hence, option C is correct ..
Answer:
It's D.
Step-by-step explanation:
The shorter period loan has the same total interest for the same loan amount, so it has the higher effective interest rate: 80/12 is higher than 89/14.
