Assume that the random variable X is normally distributed, with mean mu equals 100 and standard deviation sigma equals 20. Comp ute the probability P(Xgreater than116). 0.2119 0.7881 0.2420 0.1977
1 answer:
Answer: 0.2119
Step-by-step explanation:
We assume that the random variable X is normally distributed.
Given : Population mean :
Standard deviation :
Z-score :
Then, z-score corresponds to 116
By using the standard normal distribution table for z , we have
Hence, the required probability = 0.2119

Answer:
One Real number solution
Step-by-step explanation:
check the discriminant
12^2 - 4*4*9
b^2 - 4ac
...
144 - 16*9 = 0
one double root
To round it to the nearest unit it would be 38. To round it to the nearest ten it would be 40.
