I thought population standard deviation would be use?

Are you sure chemistry is not important for mechanical engineering?

Just apply the definition of conditional probability P(A|B) = P(A n B)/P(B) This definition can be rewritten as P(A|B) = P(A and B) /P(B) due to relationship between logic and set theory.

a) i)1.01^12 -1 ii) find n such that 1.01^n = 2 b t = 1 => (1.01)C = C*e^k Solve for k i) use the value k calculated to compute e^12k - 1 ii) find t such that e^kt = 2

I meant more in the context IT. But yeah I'll will take your word for it.

Just to add. The skill set you need to develop will depend on the job you are going for. So learning MATLAB may not necessarily be useful.

To add sin(pi-x) = sin(x) for all real numbers, x. You can see this graphically: sin(pi -x) = -sin(x-pi) since sin is odd. So sin(pi-x) is shifted pi units and then flipped across the x-axis.

The method used is interesting. You should get full marks. I will just add the gradient formula is given by (y1 - y2 ) / (x1 - x2) = m => m(x1 - x2) = y1 - y2 #Multiply by (x1-x2) #Just small note there are some minor issues but steps 3-5 are correct y - y = m(x - x) y - 6 = -1/2(x -...

For pictures 3 and 4 make sure to review related angles. make sure to remember the unit circle definitions of trigonometric functions. sin theta = y cos theta = x tan theta = y/x How can you use these definitions to answers questions 3/4 The answers given in picture 4 c/d is incorrect...

No prior knowledge of 4 unit is needed. Just go through the recommended/required textbook for the math subjects and the tutorials and it not too hard to get HD. If I am not mistaken the recommended text is stewart calculus(for first semester math) for the engineering core. So during the...

I think he is referring case of k = -2 which I missed. To shift a graph k units to the left the transformation is f(x+k) where k is positive.

k = 1 you want to shift the curve 1 unit to the right. The graph P(x-k) is shifted k units to the right. So k = 1. ii) P(x) = (x+1)(x-2)^2 So just expand (x+1)(x-2)^2.

Do I find the cos inverse of -1/2 - which is in 2nd quadrant ? Yes do exactly that. The process is the same. => cos^-1(-1/2) = 120 degrees = 2pi/3. Remember the range of cos^-1(x) is [0 , pi] and domain [-1, 1] So the general solution for cos(x) = -1/2 is x = 2*n*pi +/- 2pi/3...

Area of non-right angle triangle is 1/2(a*b)sin(theta) when triangle is in form SAS. If triangle is in form SSS or SAS use the cosine rule to find an angle or side. If triangle is in the form SSA or AAS use the sine rule. If you know basic algebraic manipulation you should be good for...

q4. There will be an intersection along the x-axis at x=a, b, c. The behaviour will depend on the powers. Suppose n is even, then the graph will touch the x-axis at x=a. If n is not even then the graph will cut the x-axis. This assumes a != b or a !=c. Similar things can be said about m, p...

@Farhanthestudent005 If you know what the the theorem are for arc length and area of sector in radians, you solve be able to solve the question.

Have you tried stackoverflow. If you need a tutorial you could try Youtube. If you want something perhaps more advanced then you culd try Udemy. THrough the link you may be able visual basic courses that you can enroll in for free. https://idownloadcoupon.com/

Think of function when a function is reused to calculate the value of it argument your dealing with recursive function e.g. Let say we have function call fibonacii(n) where n is the nth term. The output of fibonacii(n) is the nth term of the fibonacii sequence. fibonacii( nth_term) =...

I was thinking of |x+4| < 2/ (x+3) for some reason. Thank you
