Determine the length of the missing side of the right triangle

3√3

Step-by-step explanation:

You can use Pythagorean Theorem

a^2+b^2=c^2

a^2+(3)^2=(6)^2

a^2=√(36-9)=√27=3√3 or around 5.196

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
