E, Q, & W are collinear with W between Q & E. If QE = -17x + 647, EW = 7x + 11, and
WQ = 11x + 6, find x & EW.

The center of a circle represent by the equation (x+9)^2+(y-6)^2=10^2 (-9,6), (-6,9), (6,-9) ,(9,-6)

Can someone me with this problem i don't understand i need

The weight of full–grown tomatoes at a farm is modeled by a normal distribution with a standard deviation of 18.4 grams. the 95 percent confidence interval for the mean weight of the tomatoes is calculated using a sample of 100 tomatoes. what is the margin of error (half the width of the confidence interval)?
