By the Central Limit Theorem, the best point estimate for the mean GPA for all residents of the local apartment complex is 1.7.
The Central Limit Theorem established 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:
The sample of 112 residents has a mean GPA of 1.7.
By the Central Limit Theorem, the best point estimate for the mean GPA for all residents of the local apartment complex is 1.7.

Answer:
D, E and F
calculating the volume of regular bodies like prims works by multiplication alone.
you need some addition for surface area and for more complicated bodies that when the volume can't be calculated in one step
Answer:
48cm^2
Step-by-step explanation:
You first find the area (l * w) of the first rectangle on the top.
4 * 2 is 8
Then you find the area of the rectangle on the bottom.
5 * 8 is 40
Finally you add the area's together.
48
14 degrees. It equals half the intercepted arc.
