Deborah used blocks to model the following situation. How can Deborah use her model to find the number of speedboats the dealer sells if it sells 12 fishing boats? A boat dealer sells 4 fishing boats for every 3 speedboats it sells. The model can be used like a bar diagram. Since the dealer sold 12 fishing boats, each block represents _ fishing boats or speedboats. The dealer sells _ speed boats.

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.

Solve each quadratic equation by factoring and using the zero product property. [tex]x^2+6x+8=0[/tex]

There are three bags: a (contains 2 white and 4 red balls), b (8 white, 4 red) and c (1 white 3 red). you select one ball at random from each bag, observe that exactly two are white, but forget which ball came from which bag. what is the probability that you selected a white ball from bag a?
