It is assumed that the toys belonging to category 1 will last for more than 50 hours with probability 0.4, while the corresponding probabilities for toys belonging to categories 2, 3, and 4 are 0.5, 0.8, and 0.2 respectively. Suppose that 30% of the toys are in category 1, 20% in category 2, 10% in category 3, and 40% in category 4. Sarah went to the toy manufacturing company and randomly picked one toy. If the toy did not last for more than 50 hours, what is the probability that she picked the toy from category 4 (assuming the toy was in use until the battery life got over)? Enter the answer upto 3 decimal accuracy. |

The value of (sin 7x + sin 5x) /(cos 7x + cos 5x) + (sin 9x + sin 3x) / (cos 9x + cos 3x) is |
|
Answer» Answer: LHS = [(sin7x + SIN5X) + (sin9x + sin3x)] [(COS7X + cos5x) + (cos9x + cos3x)] use the FORMULA, sinC + sinD = 2sin(C+D)/2.cos(C-D)/2 COSC + cosB = 2cos(C+D)/2.cos(C-D)/2 = {2sin6x.cosx +2sin6x.cos3x}/ {2cos6x.cosx + 2cos6x.cos3x} - 2sin(x(cosx + cos3x)/ 2cos6x(cosx+cos3x) = sin6x/cos6x = tan6x = RHS hence proved if found helpful mark it as brainiliest and FOLLOW plz |
