For questions 6 and 7: One characteristic of roller coasters that contributes to the maximum speed of the ride is the track's maximum height. Computer output for a regression of maximum speed (in miles/hours) on maximum height (in feet) for vine roller coasters that opened recently around the world is shown.

step-by-step explanation:

i need the options

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
