The temperature at a point (x, y) is T(x, y), measured in degrees Celsius. A bug crawls so that its position after t seconds is
given by x = 5 + t , y = 4 + 1 4 t, where x and y are measured in centimeters. The temperature function satisfies Tx(3, 5) = 1 and Ty(3, 5) = 1. How fast is the temperature rising on the bug's path after 4 seconds? (Round your answer to two decimal places.)

Answer:
0.368
Step-by-step explanation:
Number of red marbles= 3
Number of blue marbles= 4
Number of green marbles= 7
Total number of marbles= 3+4+7= 14
Let the first ball is taken out to be red
P(R)=
than again a second ball is drawn, number of balls left= 14-1=13
Number of red= 2
P(R)=
Total probability=+
Total probability= 0.368
Hence, the correct answer is 0.368
