Answer:
The sampling distribution of the sample mean for samples of size 49 is approximately normally distributed with mean of 100 and standard deviation of 3.
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.
Population
Mean 100, standard deviation 21.
The sampling distribution of the sample mean for samples of size 49
By the Central Limit Theorem
Mean 100
Standard deviation
The sampling distribution of the sample mean for samples of size 49 is approximately normally distributed with mean of 100 and standard deviation of 3.
Answer:
= -√6
Step-by-step explanation:
1) collect like terms by subtracting coefficients:
3√6 - 4√6
(3-4)√6
2) calculate (3-4):
(3-4)√6
-1√6
3) the coefficient of -1 does not have to be written, but the negative sign remains:
-1√6
-√6
so therefore:
-√6 is your answer
Answer:
0 is the y intercept
Step-by-step explanation:
because the equation will turn into y=6x+0
but the equation will just be written as y=6x and the formula is y=mx+b and i b cant be seen at all in the end that means b(y intercept) will be 0
If brainiest is earned its greatly Appreciated
Answer:
Well the m = 2/2
The b = 0
and the final equation is y = 2/2x + 0
or y = 1x + 0
Step-by-step explanation:
The answer will be -12 and -2. Hope you get it!
