What is the length of shortest path that begins at the point (-1,1) , touches the x axis and then ends at point on the parabola $(x-y)^2 =2(x+y-4)$ . I put $x=x-y$ $y=x+y-4$ then the starting point would be $(-4,-2)$ . can I proceed by this methos of changing the coordinates After that I g...

$\mathbb{P}(\text{the signal transmitted was green | B received a green signal}) = \frac{\mathbb{P}(\text{the signal transmitted was green }\cap\text{ B received a green signal})}{\mathbb{P}(\text{B received a green singal })}$ Here, $\mathbb{P}(\text{the signal transmitted was green }\cap\text{...

Signal which can be green or red with probability 4/5 and 1/5 respectively, is received by station A and then transmitted to station B. The probability of each station receiving the signal correctly 3/4. If the Signal received at station B is green, then the probability that the ongmal signal was...

I assumed the functions to be 5x,2x and 3x respectively. Solving through this, I got option (C) as the answer. However, the answer is given as (B,C,D). Please help

How there can be two centres? the centre would be the centroind of tetrahedron. and volume between two planes should be infinite as first octant is infinte

i assume the functions as 5x,2x and 3x respectively . Solving through this I got option c as answer . but the answer is given as BCD
