Arianna and Hannah are conducting an experiment to test the difference threshold for sense of touch on the forehead. For trial 1, Hannah closes her eyes while Arianna gently touches 2 paperclip points 3 millimeters (mm) apart on Hannah's forehead. Then Hannah reports whether she could feel 1 or 2 points. For each of the next trials, Arianna and Hannah repeat this process, each time with the points 2 more mm apart. Hannah reports feeling 1 point until the points are 15mm apart, when she begins reporting that she feels 2 points. Which inequality best represents the trial numbers in which Hannah feels 2 points? a. t > 6
b. t < 6
c. t ⥠7
d. t ⤠7

t > 7

Step-by-step explanation:

2 paperclip points = 3 mm apart

After each trial, points are 2mm more apart ;

That is

Trial 1 : 3mm

Trial 2 : 5 mm

Trial 3 : 7 mm

Trial 4 : 9 mm

Trial 5 : 11 mm

Trial 6 : 13 mm

Trial 7 : 15 mm

Trial 8 : 17 mm...

Hannah reports feeling 1 point until the point are 15m apart which is equal to 7th trial

Hence, she starred reporting feeling 2 points after the 7 th trial

t > 7

Hence, the inequality

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
