Answer:
Your answer is
x-int: (3 , 0) , (-3/2 , 0)
y-int: (0 , -9)
Step-by-step explanation:
G divides each median in the ratio of 2 to 1 (the longer side goes from G to the angle)
triangle AMN is similar to triangle ABC (why?)
AMN is a scaled version of ABC (by a factor of ⅔)
its area should be scaled by (⅔)^2
Answer:

And we can use the probability mass function and we got:
Then the probability that all three have a smart phone is 0.091
Step-by-step explanation:
Let X the random variable of interest "number of students with smartphone", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:

And we can use the probability mass function and we got:
Then the probability that all three have a smart phone is 0.091
Your answer is 3/16 I think this is accurate for the problem
