Direction vector =(1−(−2),−2−(−3),4−(−4))=(3,1,8). Vector form using point (−2,−3,−4): r=(−2i^−3j^−4k^)+λ(3i^+j^+8k^).
Using simple average of relatives method, the price index for 2011, taking 2001 as base year, was found to be 127. If Σp0=263, then x and y from the following data are :
| Commodities | A | B | C | D | E | F |
|---|---|---|---|---|---|---|
| Prices (in Rs.) in 2001 | 80 | 70 | x | 20 | 18 | 25 |
| Prices (in Rs.) in 2011 | 100 | 87.50 | 61 | 22 | y | 32.50 |

If the total cost and total revenue of a company that produces and sells $x$ units of a particular product are $C(x) = 5x + 350$ and $R(x) = 50x - x^2$ respectively, then which of the following is/are the breakeven values: (A) $x = 10$ (B) $x = 25$ (C) $x = 45$ (D) $x = 30$ Choose the correct answer from the options given below:
The supply function of a commodity is P = $x^3+2x+18$. When 4 units of commodity are sold , then producer surplus is:
The demand function P for maximising a profit monopolist is given by P=274-x², while the marginal cost is 4+3x for x units of commodity. The consumer surplus is
If $y = e^{\frac{1}{2}\log(1+ \tan^2 x)}$, then $\frac{d^2y}{dx^2}$ is equal to:
If the random variable X follows the Poisson distribution such that P[X = k] = P[X = k+1], then the mean value of X is:
