Answer:
Step-by-step explanation:
Assuming this problem :"Only 30% of the students in a certain liberal arts college are males.
If two students from this college are selected at random, what is the probability that they are both males?"
Previous concepts
An independent event is an "event that has no connection to another event's chances of happening ". For this case we can assume that if one person is male and if we select another one the probability that this one would be male or female is totally indepedent from the first selection.
When we have two independent events let's say A and B and we want to find the probability that both events occurs at the same time we can use the following formula:
Solution to the problem
We can define some notation:
first person selected is a male
second person selected is male
On this case we want the probability that both would be males. And we can express this like this on math terms:
For this case we can assume that the two events are independent. And in order to find the probability for two events independents events we just need to multiply the probabilities of each one like this:
Answer:
3+3 am I right... I think I am
Answer:
B should have been the winner. Since B received the majority of the votes, he should be the winner, not A, and it doesnt matter how close was the election or how cmany votes A got in reality. If B had more votes for 1st place, then it should be the winner, not A. I am assuming that there were electoral fraud and someone intentionally didnt count valid votes from B.
Answer:
11.9 mm
Step-by-step explanation:
We can find d by applying the cosine rules.
d² = 21² + 27² - 2(21)(27) cos (25)
d² = 441 + 729 - 1027.75
d² = 142.25
d = √142.25
d = 11.9 mm (nearest tenth)
Answer:
30 is the cost of clothes Kyle bought.
Step-by-step explanation:
Given: Kyle spend 1/5 of his money on clothing.
Remaining money is 120.
Lets assume the total money Kyle had be "x".
∴ Money spent on clothes = 
Now, putting up value in the equation to find the total amount of money.
We know, money remaining is 120
Taking LCD subtract the fraction.
⇒ 
⇒ 
⇒
Multiplying 5 both side
⇒
dividing 4 on both side.
∴
∴ x= 150
Kyle has total 150 money to spend.
Kyle spent 
of his total money on clothing.
⇒ cost of clothes kyle bought= 
Hence, Kyle spent 30, which was the cost of clothes kyle bought.
