Can 27,34,43 be a right triangle

No

Step-by-step explanation:

The way to answer this is to apply the Pythagorean Theorem.

Is 27^2 + 34^2 = 43^2?  If yes, this could be a right triangle.  If no, it could not.

729 + 1156 = 1849 ??  No.  Thus, these three side lengths do not satisfy the Pythagorean Theorrem, and therefore could not make a right triangle.

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

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
