What dose scaling mean? Whats the defiition?

Step-by-step explanation: Scaling (For geometry), a linear transformation that enlarges or diminishes objects. Scale invariance, a feature of objects or laws that do not change if scales of length, energy, or other variables are multiplied by a common factor. Scaling law, a law that describes the scale invariance found in many natural phenomena.

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
