I actually just learned this. I think this is the right answer.
Answer:
n * r ^2
Step-by-step explanation:
Answer: The number of times a yellow cube will be drawn is 390 times.
Step-by-step explanation: Like the last question with the blue cubes, set up a ratio.
Since it is still 240 times drawn and we need to figure out how many times a yellow cube will be drawn from 1200 times, the top number only changes.
78/240 = x/1200
Multiply 78 and 1200, which is 93,600.
Divide that by 93,600, which is 390.
The answer is B because r is negative and less than the critical value.
3t+12-4t-6=-4
-t=-4+6-12
-t=-10
t=10
That's your answer.
