Assume that the random variable X is normally distributed, with mean mu equals 100 and standard deviation sigma equals 20. Comp

TEA [102]

Answer: 0.2119

Step-by-step explanation:

We assume that the random variable X is normally distributed.

Given : Population mean : $\mu=100$

Standard deviation : $\sigma=20$

Z-score : $z=\dfrac{x-\mu}{\sigma}$

Then, z-score corresponds to 116

$z=\dfrac{116-100}{20}=0.8$

By using the standard normal distribution table for z , we have

$P(x>116)=P(z>0.8)=1-P(z\leq0.8)$

$=1-0.7881446\approx0.2119$

Hence, the required probability = 0.2119

If you had a rubik's cube with 10 little squares on each side, and peeled off the outer layer, how many little cubes would you e

Pachacha [2.7K]

There is 6 sides in a cube, multiplying we get the number of squares:
6*10 = 60 little squares.
Peeling off one layer means subtracting 10 squares from the above numbers like this:
60 - 10 = 50.

Answer: we end up with 50 littles squares.
