What is the approximate value of 0 , if tan 0 = 7/9 ? , 38° 52° 74° 16° 63°

              if tanθ (7/9) tells us nothing.
Maybe you mean tanθ = (7/9) ???

If so, θ = tan⁻¹(7/9) = 37.874983651 ≈

38 hope I helped

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
