X³ - 12x² + 35x
x(x² - 12x + 35)
x(x-5)(x-7)
im am pretty sure it is b.sometimes because an equation can have more then one answer
Answer:
c
Step-by-step explanation:
what ever it is you do the same on the other side
Answer:
The mean of the sampling distribution of x is 0.5 and the standard deviation is 0.083.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For the population, we have that:
Mean = 0.5
Standard deviaiton = 0.289
Sample of 12
By the Central Limit Theorem
Mean = 0.5
Standard deviation 
The mean of the sampling distribution of x is 0.5 and the standard deviation is 0.083.
240 because 2000x0.04=80 X3= 240
