Write 14_3 as a mixed number

if you mean like 14/3. you would divide 14 by 3 which would give you 4 times which would equal 12 so you would have two left over that couldn't be divided by 4 and you have to keep the three so the answer would be 4 2/3. with 4 being the big number and 2/3 being the other half of the mixed fraction

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
