During an experiment, you weigh the mass of a piece of wood as 200 grams. you burn it so that the smoke released can turn a small turbine above the burning wood. afterwards, you weigh the mass of the ashes as 90 grams. why has your experiment not broken the law of conservation of mass?

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
