Answer: It is a continuous random variable.
The amount of rain is a continuous random variable because it can take on all of the numbers on a number line.
For example, the actual amount of rain in April could be 1 inch. Or 1.4 inches. Or 1.45 inches. Or 1.452020980234 inches. There are an infinite possibilities for the amount of rainfall.
The answer is 60 because 10 x 2 is 20 and 5 x 8 is 40 and add those together to get 60
The answer is B, 30 x 5 The answer is reasonable. Ryder is correct. It reasonable because if 25 x 5 is 125, then 30 x 5 won't be too much to be unreasonable. 30 x 5 is 150, therefore it is only 25 windows higher, so it is reasonable. Hope this helps! :)
This is the sum of cubes which factors to:
(x+2)(x^2-2x+4)
-4x=-20. divide -4 by both sides. x=-4/-20.
The answer is x=5
