the entire student body of 225 students took a test. these test scores have a mean of 75 , a standard deviation have a mean of 75 and a standard deviation of 10, and are slighlty positively skewed. if you randomly chose 25 of these test scores and calculated the mean over and over again, what could be the mean, standard deviation and skew of this distribution

1. what expression would be the same as 6x+x+0 2. find the prime factorization of 60 3. write the expression for 6 + x in words.

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)
