50% because when you take out the first marble witch is probably blue since there are more blue you would have 2 blue and 2 green so the chance would be 50%
Answer: 0.1
Step-by-step explanation: you only need to add zero to the first value,
for example if you have 1/10, you add zero, getting the next equation
10/10 if you add a zero to value you can add a zero to the result getting the following result
10/10=0. in this point both values are divisible
and 10 between 10 is equal to 1
as you finish add zeros you can add a point and after the 1 getting this result
1/10 = 0.1
Answer:
i will say 15 and -7
Step-by-step explanation:
15+-7=8 and 15--7=22
15+-7 so take the negative and take out that mush of the big number
15-7=8
15--7= the subtracting beside a negative makes it changes to positive and addition so 15+7=22
Answer:
The answer to your question is below
Step-by-step explanation:
2.
Just find the prime factors of 128 and simplify


3.-
Get the square roots and simplify
3i + 4i
7i
4.- None of the choices is equal to one, because the exponents are pair.
5.- 1/3x² + 10 = 7
1/3x² = 7 - 10
1/3x² = -3
x² = -3(3)
x² = -9
x = ±3i
Answer:
If the committee must consist at least one student, the probability is 99.96%
Step-by-step explanation:
Given;
number of teachers = 5
number of students = 20
Total number of committee members = 25
Possible outcome of all the members in the 4 committee = 25C₄ ways
= 12650
If the committee must consist at least one student, then the possible outcome;
= Total possible outcome - committee with no student
= 25C₄ ways - 5C₄ ways (all committee members are teachers)
= 12650 - 5
= 12645
The probability that the committee will consist at least one student;
= 12645 / 12650
= 0.9996
= 99.96%
Therefore, if the committee must consist at least one student, the probability is 99.96%
