Answer:
The probability is 0.0397.
Step-by-step explanation:
There are 9 students in a class: 5 boys and 4 girls.
The teacher picks a group of 4 at random.
So, the probability that everyone in the group is a boy is given by :
Or 
Hence, the probability is 0.0397.
Answer: 2
Step-by-step explanation:
3/5 of 30 = 18(AL)
2/6 of 30 = 10 (ML)
18+10 = 28 (AL+ ML)
the remainder
30-28 = 2 (CL)
Answer:
75 square units
Step-by-step explanation:
(x+10)x=3x^2
x^2+10x=3x^2
10x=2x^2
5x=x^2
x=5
Plugging in 5 into either of the initial equations yields the answer.
To avoid distortion of extreme
values, a good indicator would be the
B. median.
