36x - 3y = 3 reduce to 12x - y = 3 or y = 12x -3 There are an infinite number of solutions pick any x you feel like, then evaluate the corresponding y e.g. x = 1 y = 12(1)-3 = 12-3 = 9 x = -3.56 y = 12(-3.56) -3 = -45.72 etc. To have the instruction: "Determine X and Y&qu...
The probabilities are correct your total should be the total of the probabilities. 5/10 + 3/10+2/10 = 10/10 = 1 If the total is supposed to be the total of prob's don't say 10 , it is 10/10 or 1
" ... as shown " ????
Ok, Xian, I will answer no more until you show me some work of your own, or give some indication where your problems lie.
find the circumference of the wheel. Find the circumference of the circuit, multiply it by 12 , then divide by the circumference of the wheel change everything to metres. Since you are in the metric system, this is very easy to do.
D1/D2 = 5/9 D1 = √(5^2 + 8^2) = √89 so √89/D2 = 5/9 5D2 = 9√89 D2 = 9√89/5 notice that the diagonal increased by a factor of 9/5 or the same as the increase in the sides.
the three circles can cut each other in 6 different points (think of a typical Venn diagram) A line can cut a circle in 2 point so each line can cut all the circles in 6 points so total = 6 + 6 + 6 = 18 BUT, let's not forget that the two lines can also intersect so the tot...
asking for a teacher's opinion
I would never want to presume that I could accurately evaluate a student totally objectively even in a subject like Mathematics. We conducted a workshop in our Math Department once, where we each marked the same paper each marker given the same "marking scheme" . Mar...
call them b , for "big" and s for "small" so you have 6 b's and 2 s's prob = (6/8)(5/7)(4/6) = 120/336 = 5/14
prob all three defective = (.04)^3 = .000064 My question to you: What would it be if he had not returned the clocks after checking them?
