3n^2+7n-6n-14+4n^2+6n= 7n^2+7n-14
Hope that helps and best of wishes!
Answer:
And replacing we got:
Step-by-step explanation:
Let X the random variable of interest "number of craked eggs", 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 find the probability:
And replacing we got:
Yes. Take for example a square and an ellipsis with the same perimeter. The family of ellipses with the same perimeter can have any area between that of a circle to zero (if it is extremely “thin” i.e. if its eccentricity is large). The circle has the maximum area of any other shape with the same perimeter, so the square has the same area of one of the intermediate ellipses.
So,
There are 7 cherry gumballs and 6 grape gumballs.
The total gumballs is 13.
Therefore, the ratio of grape gumballs to total gumballs is 6:13.
