What is the area of the composite figure?
(6pi + 10) m2
(10pi+ 10 m2
(12pi+ 10) m2
(16pi+ 10) m2

the first one

Step-by-step explanation: find the area of half of the small circle and half of the big circle. Then subtract them. Then add that answer to the area of the rectangle

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
