This works good with the factors because you work step by step, making an equation like this one
First you must convert the denominator to an equal number by finding a same multiple, in this case it is 12. So the factions convert to 3/12 and 8/12. Now add the two, resulting in 11/12. So the answer is 11/12
Answer:
It is going to be bell-shaped(normally distributed), with mean
and standard deviation
.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, a large sample size can be approximated to a normal distribution with mean
and standard deviation
.
What can we say about the shape of the distribution of the sample mean time?
It is going to be bell-shaped(normally distributed), with mean
and standard deviation
.
Answer:

Step-by-step explanation:
the quadratic formula is:

a= -2, b = -1 and c =-3
Putting values in the formula
