In terms of probability related to a distribution of sample means, why is it that is it more likely for you to obtain a sample mean that is close to the population mean rather than very far away from it?
O Sample means pile up around the population mean
O Distribution of sample means are very skewed
The sample mean is usually an outlier
Sample means pile up far away from the population mean

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
