easiest way: since the two lines are parallel, they will differ only in the constant. so let the new line by x + 4y = k but (7,9) lies on it so 7 + 4(9) = k k = 43 for an equation of x + 4y = 43 change to y = mx + b form 4y = -x + 43 y = (1/4)x + 43/4

Trig
Circumference = 2(pi)12.96 = 81.43 so 18/56 = x/81.43 x= 18(81.43)/56 26.17 sec for 1 rotation of the wheel so the angular velocity = 2pi/26.17 or .24 radians/second

Math
Let N be the number of 1 mark questions. 43/N = 96/100 N = 100*43/96 = 44.79 Since N has to be an integer, so we need to round 44.79 to the nearest integer. In addition, as a check, divide 43 by N to make sure we get back 96%.

Just did the exam for this course last week. So there are 86 people out of 100 who are universal recipients, while the other 14 aren't. (I think that's what your data is telling me.) We can use the binomial probability formula: P(X=r)=nCr(p^r)((p-1)^(n-r)) So since we ...

(low price + median price + high price)/3 = 14544.43 (the mean price). Therefore, lp + median + hp = 3*14,544.43 = 43,633.29. Subtract the median and lp + hp = 43,633.29 - 14833.02 = 28,800.27. That divided by 2 = 14400.135. So add 1/2 the range to this and subtract 1/2 the ...

OK there is quite good routine way to do these.... C H O 48.65% 8.11% 43.24% if we had 100 g 48.65g 8.11g 43.24g so number of moles of each is 48.65/12 8.11/1 43.24/16 4.05 8.11 2.70 divide by smallest 1.5 3.0 1 or 3 6 2 so the empirical formula is C3H6O2
