Answer:
no
Step-by-step explanation:
because triangle abc and triangle acer have unequal ratio of side lengths
Okay so multiples of 3 on a 10 sided die is 3,6,and 9 so 3/10 times
if your rolling it 250 times you cross multiply with x so the equation would be 3/10= x/250
do 3x250 which is 750
750//10 is 75
x=75 so its your answer:)
Answer:
And we know that each time that we win we recieve $1 and each time we loss we need to pay $1, so then the expected value would be given by:
And the variance is defined as:
Step-by-step explanation:
For this case we know that we can win if we select 2 balls of the same color, so we can find the probability of win like this:
So then the probability of no win would be given by the complement:
We can define the random variable X who represent the amount of money that we can win.
And we can use the definition of expected value given by:
And we know that each time that we win we recieve $1 and each time we loss we need to pay $1, so then the expected value would be given by:
We can calculate the second monet like this:
And the variance is defined as:
Answer:
5
Step-by-step explanation:
it's a reversed function you just need to reverse the values
Bbbbbbbbbbbbbbbbbbbbb is the answer
