Sal recorded the cost of his monthly home heating bill and the corresponding average monthly temperature for the past 15 months. He displayed the information in a scatter plot and used a graphing calculator program to find the least squares regression line to fit the data. Sal wants to use the least squares regression line to predict the cost of his heating bill when the average monthly temperature is 40°F. Which statement is true?

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

i think it is 18
