Factorise the following completely 6x(squared) + 11xy + 5y(squared)

Step-by-step explanation:

Factor the following:

The coefficient of x² is 6 and the coefficient of y² is 5. The product of 6 and 5 is 30. The factors of 30 which sum to 11 are 5 and 6.

So,

Factor (x + y) from 6x(x + y) + 5y(x + y):

It's a trick question, if you read it carefully it says 5% of the students who received As on their final projects also received As on their final exams. And the question is Find the probability that a student chosen at random received an A on both the final exam and the final project. Its the same thing, so its 5% of students
