Answer:
The standard error of the mean for this sample is 9.033
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.
In this problem, we have that:
So
The standard error of the mean for this sample is 9.033
Since the shape is a parallelogram and the formula to finding a parallelogram is base times height .the picture shows that the height is 11 and the width is 3. all you have to do is 3 times 11 = 33. I know the length is 11 cuz a parallelogram is just a rectangle but you have to rearrange it . So it makes sense that the length is 11
Answer:
x=3.6
Step-by-step explanation:
parentese first so add 34+20= 54
5x54=36
-54=-54
5x= -18
5x/5x -18/5x
x= 3.6
Step-by-step explanation:
she swims at least 45 min's a day
(5,0) and (8,4)
it’s the only one when graphed that the line (from left to right) goes up,
