Actual time in seconds recorded when statistics students participated in an experiment t test their ability to determine when one minute 60 seconds has passed are shown below. Find the mean median mode of the listed numbers. 55 51 70 64 68 60 49?49

Step-by-step explanation:

mean add upp all the numbers and divide by how many they are

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
