The class mark of a particular class in a continuous frequency distribution is25 and class size is 10. Find the class interval |
|
Answer» Answer: Let LOWER Limit be L ∴ Upper Limit =L+10 [ SINCE, Class Width =10] Now, we know that ClassMark=(LowerLimit+UpperLimit)÷2 ∴ (L+L+10)÷2=25 [Class MARK 25 given] ⇒ 2L+10=50 ⇒ 2L=40 ⇒ L=20 ∴ Lower Limit of the class =20 Upper Limit of the class =20+10=30 The required class is 20−30 |

Answer» Answer: √9π Step-by-step explanation: 13. No, because the probability of the particle existing in a narrow (infinitesimally small) interval at the discontinuity is undefined. 15. No. For an infinite square well, the spacing between energy LEVELS increases with the quantum number n. The smallest energy measured corresponds to the transition from n = 2 to 1, which is three times the ground state energy. The largest energy measured corresponds to a transition from n=∞ to 1, which is infinity. (NOTE: Even PARTICLES with extremely LARGE energies remain BOUND to an infinite square well—they can never “escape”) |

Answer» Answer :-
Step-by-step explanation:To Find :-
Given to solve :
Solution: By SIMPLIFYING both sides, By EVALUATING the like TERMS step-by-step on L.H.S, By evaluating the like terms step-by-step on R.H.S, By transposing -15 to R.H.S and evaluating By transposing -2y to L.H.S and evaluating, Hence, The required number is -3. ____________________________________ Now, Verification
We have,
By putting the value of y on L.H.S and R.H.S seperately,
By putting the value of y,
By putting the value of y, Now, we have,
∴ L.H.S = R.H.S Hence, Verified! |

3. Diagonals AC and BD of a trapezium ABCDwith AB II DC intersect each other at thepoint O. Using a similarity criterion for two triangles, show thatOA/OC = OB /OD |
|
Answer» Answer: In △DOC and △BOA, AB || CD, thus alternate interior ANGLES will be equal, ∠CDO = ∠ABO Similarly, ∠DCO = ∠BAO Also, for the two triangles △DOC and △BOA, vertically OPPOSITE angles will be equal; ∠DOC = ∠BOA Hence, by AAA similarity criterion, △DOC ~ △BOA Thus, the corresponding SIDES are proportional. DO/BO = OC/OA OA/OC = OB/OD Hence, proved. |
