WILL GIVE BRAINLEST 18. Find the inverse of {(4, -1), (3, -2), (6, 9), (8, 5)}.
F. {(8, 5), (6, 9), (3, -2), (4, -1)}

H. {(-1, 4), (-2, 3), (9, 6), (5, 8)}

G. {(-4, 1), (-3, 2), (-6, -9), (-8, -5)}

J. {(-1, -2), (9, 5), (4, 3), (6, 8)} 19.

H. { (-1, 4), (-2, 3), (9, 6), (5, 8)}

Step-by-step explanation:

I. Given (-1, 4) , when -1 is x.value and 4 is y.value

  In this case x is also Domain and y is also Range

  Inverse value means switch x to y or y to x

So inverse of (-1,4) is (4,-1)

Hope that help :)

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
