Is this a right triangle?
16 inches, 30 inches, and 34 inches
O NO
O YES

Yes

Step-by-step explanation:

To be able to make a right triangle, it needs to follow the Pythagorean theorem

Thus, 16^2+30^2=34^2 needs to be true

256+900=1156

and sqrt1156=34

so yes

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
