Systems<span> of </span>linear equations<span> can only </span>have<span> 0, 1, or an infinite number of </span>solutions<span>. These </span>two<span> lines cannot intersect twice. The correct answer is that the </span>system<span> has one </span>solution<span>.</span>
So in event A the probability will be 12/20, which is 3/5. In event B the probability will be 11/19. Multiplying these probabilities we get the probability of both occuring, which is (11*3)/(5*19)=33/95
Area of the field should be 9*10 = 90 square feet.
a bag of grass seeds cover 15 square feet.
so if you need to know how many bags should be used, then,
Total area of field/ area covered by 1 bag of grass seeds.
= 90/15 = 6 bags
he needs to use 6 bags of grass seeds to cover the whole field.
I don't think there are any 'hidden' questions, though you can consider the 2nd part of the question I guess. (how many bags of seed will Paul...)
