Aset of data containing the heights of ten students, in centimeters, of some students is shown below. {160, 169, 170, 179, 180, 189, 190, 199, 200, 209} this set of data is represented by the following histogram:

Ibelieve it's a. 2.2 - x = -10.85 (plz tell me if it's right : ) )

The answer is 30 minutes to an hour

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
