Identify the surface area of the composite figure. Anwers:
S = 576 m2
S = 464 m2
S = 704 m2
S = 512 m2

512 m^2

Step-by-step explanation:

surface area of the pyramid without the base=8×12×1/2×4=192

surface area of the square without one side=8×8×5=320

total surface area=192+320=512

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
