Which equation represents the area of δabc?
a) a = 1/2 bc(sin a)
b) a = 1/2 ba(sin a)
c) a = 1/2 ac(sin a)
d) a = 1/2 hc(sin a)

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

answer: 12   they all have at least 28 days
