Round your answer to the nearest thousandth. 43.946 0.596 0.035 0.981 (1 point) 46. The table shows the temperature (in degrees) for eight consecutive days as well as the (1 point) respective number of ice cream cones an ice cream shop sold on each of these days. Temperature 68 77 83 85 89 94 96 99 Number of Cones 403 447 457 465 489 503 543 576 About how many ice cream cones would you expect the shop to sell if the temperature one day is 106 degrees? Find a line of best t for this data and use it to make your prediction. 579 cones 585 cones 602 cones 617 cones 47. You use a line of best t for a set of data to make a prediction about an unknown value. The (1 point) correlation coefcient for your data set is 0.984. How condent can you be that your predicted value will be reasonably close to the actual value? I can't be condent at all; this is about as close to a random guess as you can get. I can be a little condent; it might be close, or it might be way off. I can be very condent; it will be close, but it probably won't be exact. I can be certain that my predicted value will match the actual value exactly
