Ok, so here:
Remember for basic probability, you have to do: Probability=Events/Possible outcomes. For multiple events, you have to multiply all together.
The probability the first guy that shows up will be 8/14, because out of the 14 people, 8 of them are men. This however isn't your answer, note the question says "Separately"
The probability the second person that comes in is a dude is 7/13, because you have the first guy already in, and only 13 left.
The third person to come in being a dude has a probability of 6/12
The fourth person to come in being a dude has a probability of 5/11
When you have multiple events, the way to solve probability is to find the chances of each as a fraction, then multiply them together.
8/14 * 7/13 * 6/12 * 5/11=1680/24024
1680/24024=168/168 (168 goes into both)
Your final answer is 10/143
~Hope this helps!
Answer:
Alignment Heuristic parameters.
Step-by-step explanation:
The students' cognitive maps shows them in a straight row because the students have used "Alignment Heuristic" parameters.
Answer:
16
Step-by-step explanation:
Divide 64 by 8 to get 8. this is 1/8 of the books.
3/8 were non fiction, or 24
1/4 (2/8) were picture books, or 16
5/8 were non fiction or picture books, so ’the rest‘ of the chapter books is 3/8.
3/8 were chapter books, or 24.
add the amount of picture books and chapter books since they are the fictional texts.
16+24=40
subtract the amount of non fictional books from the amount of fictional books to get the sum.
40-24=16
The area of a circle:
A = πr²
dA/dr = 2πr
We are given dA/dt, using the chain rule
dr/dt = dA/dt x dr/dA
dr/dt = 1 x 1/2πr
When circumference = 2 cm:
2 = 2πr
r = 1/π; putting this value of r
dr/dt = 1/2π(1/π)
dr/dt = 1/2 cm/s
The radius is increasing at a rate of 1/2 cm/s.
