From AA3+2=AAA, it follows that 3+2 equals A, so A must be 5.
Given CC6+6=CBB, since 6+6 equals 12, the final digit has to be 2, making B=2. Additionally, adding 6 to 6 increases the tens digit by one, meaning B is one more than C, so C=1 (since 2-1=1). Therefore, ABC equals 521.

Is it possible to form a square whose area is 18 by connecting four lattice points? Explain.
babunello [11817]
Observe the squares... 13 is attainable owing to it being expressible as the sum of two squares (integers) 9 + 4.. utilize (0,3) and (2,0)... derive the square roots and assign them to different coordinate axes... for a more straightforward value. However, no such representation exists for 15... There is a representation available for 18... 18 = 3^2 + 3^2... try (0,3), (3,0), (3,6), (6,3).

The random variable KK has a geometric distribution with mean 16. Which of the following is closest to the standard deviation of
Inessa [12570]

Answer:

E 240

Step-by-step explanation:

Mean of the geometric distribution = (1- p) / p

16 = (1 - p) / p

16p = 1 - p;  17p = 1; thus, p = 1/17 = 0.058  

Standard Deviation = (1 - p) / p^2

= (1 - 0.058) / (0.058)^2

0.942 / 0.003364

= 280, which is closest to 240
