The yearly data have been published showing the number of releases for each of the commercial movie studios and the gross receipts for those studios thus far. The regression line equation is y′=+93.181+7.28x. The correlation coefficient is =r=0.871 . Compute the standard error of the estimate rounded to at least two decimal places, if appropriate. Assume α=0.05. No. of releases, x 361 12 35 10 306 22 21 270
Gross receipts, y (million $) 3844 154 334 241 1371 1064 125 1962

The standard error of the estimate should be calculated.

At a pizza shop 70% of the customers order a pizza 25% of the customers order a salad and 15% of the customers order both a pizza and a salad if s customer is chosen at random what is the probability that he or she orders either a pizza or a salad

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
